Macromolecules are the four biopolymers nucleic acids, proteins, and carbohydrates, lipids, as well as non-polymeric molecules with large molecular mass such as lipids and macrocycles.Carbohydrates act as quick energy and help with structure support for cells.Proteins may provide structure, serve as enzymes to speed up chemical reactions, and provide some energy.Lipids make up their plasma membrane, provide cushioning and insulation in larger organisms, and help with energy storage.Nucleic Acids carry all the codes for the functioning of the cell, have the ability to make new cells, and to heredity. Carbohydrates, or saccharides, are sugars and starches, which provide energy for humans and animals, and cellulose which make up many plant
Carbohydrates are biomolecules that consist of a chain or ring of carbon atoms attached to hydrogen and oxygen atoms. The simplest formula for carbohydrates is (CH2O)n. Carbohydrates are important to organisms for a variety of reasons. They are used to form the structural components of the cell, aid in energy storage, and serve as intermediary compounds for more complex molecules. Carbohydrates are classified as either monosaccharides, disaccharides, or polysaccharides. Both monosaccharides and disaccharides dissolve easily in water. Carbohydrates are produced in plants through the process of photosynthesis and animals obtain these carbohydrates by eating the plants. ("BIO 1510 Laboratory Manual," 2016)

Starch is more easily digested than cellulose. Grains are easy to digest as they are 60-80% starch. A recent study conducted by Sharon R. Bullimore et al.
Benedict, Biuret, Iodine and brown paper bag tests were conducted in order to identify various macromolecules which might be present in the two unknown substances given. Qualitative data was gathered on the bases of clarity, viscosity, odor, state of matter and most importantly color change. The data gathered was then complied in table two of this lab.
Sugar: A simple carbohydrates that may be any of the simple sugars. The body uses it as a source of energy, but if not used by the body or if too much is eaten it is stored throughout the body as
In biology we are currently learning about the four classes of macromolecules. These four classes go hand in hand in correctly fueling our bodies as we train and gear up for our fall marathon. Specifically, I would like to introduce you to a method of food intake, If It Fits Your Macros. This method is backed in biology as macros stands for macromolecules and divides food intake into: 40% carbohydrates, 40% protein, and 20% fats (lipids). These ratios have been specifically formatted towards endurance athletes, such as ourselves, to efficiently fuel our bodies to promote muscles growth, provide energy during our training, and keep consistent energy levels all day long.
Introduction:Carbohydrates are molecules that contain Carbon, Hydrogen, and Oxygen. The most basic sugar- carbohydrate is the monosaccharide. Carbohydrate molecules are categorized by the number of carbons present in the molecule. Glucose, the most common monosaccharide has six carbons per molecule, which is called a hexose. Carbohydrates also have a 2:1 hydrogen to oxygen ratio. This aids in the condensation and hydrolysis reactions.
Chemistry is vitally important in our understanding physiology. The molecule of my choice for this final exam is Carbohydrates. Carbohydrates are originated as the outcome of photosynthesis, the condensation of carbon dioxide that requires light energy and chlorophyll pigment. Carbohydrates are a huge source of something called metabolic energy, which can be found in plants which help feed our animals. Carbohydrates are found in sugars and starches but they have another purpose which is called cellulose which helps transport the compound ATP. Carbs are called saccharides and if they are considered sugars. The complexity of carbohydrates which are monosaccharides and complex carbs which consist of polysaccharides disaccharides and oligosaccharides. Carbohydrates represent the main source of energy for the human body. All carbs can be broken down into sugars and absorbed into our intestines and blood stream. Your body uses the glucose formed as fuel for energy. Different carbs digest and break down at different rates. When our blood sugar levels increase our pancreas pumps insulin into our blood stream. Simple carbs turn into glucose faster where complex carbs slowly turn into glucose. The foods we eat that contain carbohydrates cause our blood sugar levels to increase, transporter proteins push the glucose into our muscles, liver cells and fat where our bodies store or end up using the glucose. The cells in our bodies can’t directly use the glucose, so it has to be converted into molecules that cells then use as an energy source. One of the most important molecule for energy storing is the adenosine triphosphate known as ATP. When our cells contain oxygen it can then turn glucose into the ATP molecules using some chemical rea...
carbohydrates one of them is starches, and the second one is sugar. Starches are large polymers
Carbohydrates are the most abundant biomolecule on Earth. “Carbohydrates are used as accessible energy to fuel cellular reactions and for structural support inside cell
Macromolecules are small molecules that joined together to form one large molecule within a cell. The four classes of macromolecules are;
Carbohydrates For my health project, I did carbohydrates. They are the bodies energy source. Carbohydrates supply the body with the energy it needs to function. They are found almost exclusively in plant foods, such as fruits, vegetables, peas, and beans.
The two categories of macromolecules that the molecular biologists focus on are: nucleic acids among which most famous of nucleic acids DNA (deoxyribonucleic acids) which is the constituent of genes and proteins that are the active agents of living organism (Walker, 2009).
They include simple sugars and more complex form starch and glycogen (The Open University, 2015c). Their presence is in rich food such as flour, potatoes, rice, pasta and pulses. Carbohydrates are converted into blood sugar through the process of digestion. Glucose is the only energy source sugar in human cells which affect blood sugar level. Glycogen as polysaccharides is derived from plants and stored in the liver and muscle tissue. Starchy food such potatoes are a good source of fibre which as the indigestible component is keeping our bowel active and
There are four major classes of building blocks that are involved in the sythesis and maintance of life. These molecules of life are made up of four large biomolecule classes, Carbohydrates, proteins, lipids, nucleic acids. All four of these biomolecules are considered Organic due to a typical concentration of carbon within the molecules, carbon is broadly known as the “element of life” (Chyba & Phillips, 2002). These so-called organic molecules found as mono micromolecules bond together to form much larger macromolecules commonly found within cells. These Macromolecules are much larger than the original building blocks and are composed of thousadnsd of covalently connected atoms. An example of this relevent to humans and health would be the 25 amino acid hormone Hepcidin which is involved in the regulation of “systemic iron homeostasis”, (Nemeth & Ganz, 2006). Three of these biomolecule classes fall
Explain how the body functions using biomolecules. Biomolecules are an organic molecule in an organism. Polymers are broken down into monomers and grouped into 4 groups, proteins, carbohydrates,lipids, and nucleic acids. All these biomolecules do something for the body and every human being needs these things to survive. Without biomolecules you wouldn’t have energy and yours cells would not function correctly and without your cells working correctly your body would not function correctly. So without biomolecules a lot of things would go wrong in your body. So below I have listed proteins,carbohydrates,lipids, and nucleic acids. I listed their functions and structures and some interesting facts about them.
