Unknowns Prac.
The aim of the above practical is to identify the unknown micro and macro nutrients that reside in three unknown solutions using a series of biochemical tests.
Introduction
Micronutrients, as opposed to macronutrients (protein, carbohydrates and fat), are made up of vitamins and minerals which are required in small doses to ensure normal metabolism, growth and physical well‐being.
• Vitamins – Which are essential organic nutrients, most of which are not made in the body, or only in insufficient quantities, and are mainly acquired through food. When a person’s intake is deficient, vitamin deficiency disorders are the consequence. However vitamins are only present and required in minute quantities, compared to macronutrients, they are as crucial to health and need to be considered when determining nutrition security.

By eating a healthy balanced diet which includes plenty of nuts, green leafy vegetables and whole grains. Eating plenty of colourful fruits and vegetables, like red grapes, yellow bananas, cherries and carrots. Ensuring a person eats a balanced diet should be sufficient enough to acquiring an adequate amount of micronutrients.
Macronutrients are environmental substances used for energy, growth, and bodily functions by organisms. Depending on the nutrients the substances needed will either be in a small amount or a large amount. Nutrients needed in large amounts are called macronutrients.
The three macro-nutrients required by humans are: carbohydrates (sugars), proteins, and lipids (fats). Each macronutrient provides energy in the form of calories.
Carbohydrates
Carbohydrates are consumed in greater quantities of all the macronutrients. Currently, the National Health Service (NHS) recommends that adults get 45-65% of their daily calorific intake from carbohydrates. Carbohydrates are an important part of everybody 's diet for many
In the year 2010, the documentary Fat, Sick, and Nearly Dead was released. In the film, Australian native Joe Cross has realized that his health is worsening very fast. So Cross finally decides that he will turn his life around by taking an extreme diet that will deprive him of macronutrients for 60 days. Macronutrients are nutrients found in foods other than fruits and vegetables. Micronutrients are those nutrients found in fruits and vegetables. Micronutrients provide minerals such as Vitamin A, Iodine, Iron, Folate, and Zinc. While the body does not need these in large amounts, they are essential to the body because they help develop disease prevention and promote well-being. Micronutrients are important to include
Nutrition in humans is a product that require to supply the human body to function, nutrients also helps to prevent any disease in human organs.
Macronutrients and micronutrients are both very important for the human body. Macronutrients are the nutrients that the body needs in larger amounts, while micronutrients are not required in large amounts but a steady supply is necessary for proper functioning in the body system. Macronutrients give energy to our bodies that we need to grow properly and metabolize our food as well as function in other ways. Macronutrients consist of carbohydrates, proteins and fats. Micronutrients are the different types of vitamins and minerals needed by the
Each of the three major macronutrients — proteins, fats and carb — has important and distinct roles in the body when it comes to weight management, hormonal balance, immunity, development and so on. Here are some of the most important reasons why we need each macronutrient:
When one hears the three words: vitamins, nutrients, and minerals, they think of one thing-being healthy and noticing what your intake is daily. Nutrition is all about vitamins and nutrients. Firstly, vitamins are an organic compound required by the body in small amounts of metabolism, to protect health, and for proper growth of children. Vitamins also assist in the formation of hormones, blood cells, nervous systems chemicals, and genetic material. There are 13 well-identified vitamins. Some examples of the 13 well-identified vitamins are: A, D, E, and K-fat contained foods, B, C-consumed immediately. A well known and commonly used in commercials for orange juice vitamin is vitamin C. Vitamin C or ascorbic acid is important in the synthesis and maintenance of connective tissues. The lack of vitamin C will result in a sickness called scurvy. Scurvy harms the gums, mucous membranes, and the skin. Another well-known vitamin and is also used to commercial to give more information about this beverage is the vitamin in milk. The vitamin in milk is vitamin D. If you do not drink milk and obtain this vitamin, your bones and teeth will become soft and weak. Lacking one or more of the 13 well-identified vitamins will cause sickness and weakness to your body. Secondly, nutrients are how the body assimilates certain compounds. Nutrients are classified in 5 major groups: proteins, carbohydrates, fats, vitamins, and minerals. One of the five nutrients is carbohydrate. The carbohydrate group principally consists of sugar, starch, dextrin, cellulose, and glycogen. In more basic terms, carbohydrates are sugars needed by human and other living organisms. Some types of foods that contain carbohydrates would be candies, ice cream, fruit juice, soda, chocolate bars etc. Lastly, vitamins are connected to minerals. Minerals are also a very important part of a healthy person. There are 11 major groups of minerals. They are: calcium, chromium, copper, iodine, iron, magnesium, manganese, phosphorous, potassium, selenium, and zinc. All these terms look very familiar if one has taken chemistry. These are the elements of our world. One of the more common minerals that most people have heard of is calcium. Calcium also helps with the structure and strength of teeth and bones. Vitamins and minerals work together to help humans maintain a healthy body. For example, vitamin D works with calcium to help for and maintain the strength of teeth and bones.
Nutrition experts in the United States and Canada have a list of standards with four list values. These list values are called the Dietary Reference Intakes. The DRI committee sets these values for vitamins, minerals, calories, and nutrients. These nutrients include fat, carbohydrates, protein, fiber, and water. These list values measure the nutrient intakes of healthy people, and its major goal is to help prevent chronic diseases.
The Barfoed’s test for monosaccharides is used to differentiate between monosaccharides, disaccharides, and polysaccharides. Because of the acidity of the solution, only monosaccharides are able to reduce the copper ions. The solution will go from a sky blue to a red precipitate when there is a positive reaction for a monosaccharide. ("BIO 1510 Laboratory Manual,"
“If we could give every individual the right amount of nourishment and exercise not too little not too much, we would have food the safest way of health” (Barasi.E.M, 2003). This essay is going to discuss on the important of six essential nutrients in human body. According to PosnerB.M (1998), he define essential nutrients as a nutrients that the body cannot synthesize on its own-or not to an adequate amount and must be provided by the died. Oxford dictionary (2009), also define essential nutrients as are those nutrients that are required by the body and cannot be synthesise in the adequate amount to meet requirement, so must be provided by the diet. Essential nutrients are those found to be essential to human life and optimal function, Williams.M. H (2006).There are six main type of nutrients used to maintain body health. They are carbohydrates, protein, fat, vitamins, minerals and water. They must be in balance for the body to function properly.
The human body requires small amounts of nutrients in microgram or milligram quantities in our diet because it cannot synthesize the necessary amounts on its own. These nutrients are considered micronutrients. Micronutrients are a combination of water, vitamins, and minerals. Vitamins are organic compounds that do not provide energy, but are essential to the body in helping “aid in metabolism, as well as the growth, development and maintenance of body tissues” (Byrd-Bredbenner, Moe and Beshgetoor 402). Vitamins are broken down into two groups, water-soluble and fat-soluble. The water-soluble vitamins are the B-vitamins, and vitamin C. The fat-soluble vitamins are A, D, E, and K. Minerals are needed in even smaller amounts, however these inorganic substances are necessary for “cell metabolism, nerve impulse transmission and growth and development” (Byrd-Bredbenner, Moe and Beshgetoor 485). Minerals can be categorized into major or trace minerals. The major minerals include Sodium, Potassium, Chloride, Calcium, Phosphorus, Magnesium, and Sulfur. Trace minerals are Iron, Zinc, Copper, Manganese, Iodine, Selenium, Chromium, Fluoride, Molybdenum and Ultratrace minerals.
The main reason we eat is to nourish our bodies so we can convert it to the energy we need on a daily basis. Macronutrients and micronutrients are an essential to get us through our day however, our diet may lack either or. You can improve your nutritional health by eating a variety of foods from the food pyramid. For example eating a variety of fruits, whole grains, vegetables, dairy products, legumes and lentils. Food sources that are rich in Vitamin A are eggs, beef liver, fish, cheese, dark green often leafy vegetables (broccoli, spinach, kale), orange and yellow vegetables and fruits (carrots, cantaloupe, squash, apricots, sweet potatoes, papaya, pumpkin, mangoes) and bell peppers (red). Adding on, these foods may be high in saturated fat as well as cholesterol. In my opinion, this is the best way to fulfill the daily requirement of vitamins recommended for your age group and sex. A balanced diet of including something from every food group will be beneficial towards your health. Furthermore, dietary supplements are not necessary unless you’re deficient of this Vitamin
Vitamins are essential aids in many body processes, converting food the energy, building and maintaining cells, and other functions.
The macronutrients a person consumes are what the body needs to function properly. They are the nutrients from protein, fats and carbohydrates that make up a person's daily nutrition. The amount of macronutrients and ratio of one to the other is what people alter to achieve a certain result. For example, lowering carbs and fats while amping up on protein is what body builders do to gain more muscle. Runners will lower protein while increasing carbs to give themselves a rush for a big races.
The most important nutrient categories are starches, minerals, sugars, and electrolytes. Starches and minerals fit into the area of complex carbohydrates. Complex carbohydrates are polysaccharides (many sugars bonded together). Because of the multiple bonds, polysaccharides are able to store energy for later use. Simple sugars make up the other group of carbohydrates. The bonding structures of simple sugars are much less advanced that than those of complex carbohydrates. This allows for the burning of simple sugars in an athlete's body. Electrolytes are a category of their own because they are helpful to an athlete all of the time, whether energy storage or energy burning is needed.
6 types of nutrition Did you know that nutrition breaks into 6 groups? They are water, vitamins, fats, proteins, carbs, and minerals. Everyone should be eating these in order to keep themselves healthy. All 6 of them do different things for your body.
Plant nutrition is area of plant biology that is of the utmost importance for the proliferation of plants. Without proper nutrition, plants would simply cease to exist unless drastic alterations were made. There are certain elements that are required for the plant to grow and reproduce; these elements are known as essential elements. There are three requirements of an essential element: the element must be required for the completion of the plant’s life cycle, the element must not be replaceable by another element in whole, and finally the element must be direction involved in the metabolism of the plant. Chemical compounds that are involved in proper nutrition have been designated as nutrients, and further classified as macronutrients and micronutrients. Macronutrients are needed for growth, metabolism, and many other functions, but are designated as “macro” because they are required in larger amounts. Macronutrients include carbohydrates, proteins, and fat molecules. Micronutrients have a much wider function that depends on the exact micronutrient. Micronutrients are designated as so because they are needed in much smaller amounts when compared to macronutrients. Examples of micronutrients include vitamins and minerals.
