declined. NaClO-NH3 is macromolecule compounds with a large inter surface area. It contains abundant functional groups such as hydroxyl (OH), carboxyl (COO), quinone, amino (–NH2), etc, which determines that NaClO-NH3 is a salt of strong base and weak acid, as well the ionization equilibrium and hydrolytic equilibrium would be complicated. When the pH of the NaClO-NH3 solution was acidic, the functional groups such as OH, COO and NH2- would react with H+ to generate the NH3 sediment, resulting in a decrease
RNA, 3 had the nucleic acids from the liver extract supernatant, 4 had water, and 5 had the unknown. 2ml of Dische’s reagent was then added to each test tube. All of the test tubes are then place in boiling water. After 15 minutes in the boiling water, we recorded the color of each of the different test tubes in a table. Orcinol Test. 5 clean test tubes were label from 1-5. 1ml of different solutions were then added to different tubes. Tube 1 had DNA, 2 had RNA, 3 had nucleic acids, 4 had water, and
Nucleic Acids are the sole reason we human beings are different from a banana, from an elephant, or from a chimpanzee. All living things in this world are unique because of the order of 4 bases arranged in different patterns to form DNA. DNA is the blueprint for every organism. The blueprint needed to build us resides in most of our cells. This information is a sequence of four nucleotides arranged in a specific pattern. For example, cows have 80% of a human's DNA. DNA provides the map of the proteins
has a primary and secondary audience that it tries to address their argument. In the article called “A Structure for Deoxyribose Nucleic Acid.”, by Watson, James, and Crick, Francis, the article is a great example of how rhetoric works in a writing piece. One example that the article is rhetorical is it provides a strong argument as to why the Deoxyribose Nucleic Acid structure model created previously by two scientists called Pauling and Corey is inadequate to how the DNA structure appears and
An experiment to determine the amount of urea in a specimen of urine. Introduction. Metabolism produces a number of toxic by-products, particularly the nitrogenous wastes that result from the breakdown of proteins and nucleic acids. Amino (NH2) groups are the result of such metabolic reactions and can be toxic if ammonia (NH3) is formed from them. Ammonia tends to raise the pH of bodily fluids and interfere with membrane transport functions. To avoid this the amino groups are converted into urea
lipids and nucleic acid. I will also describe the functions and why they are important in our bodies. Proteins ======== Proteins are polymers of amino acids that are joined head-to-tail in a long chain that is then folded into a three-dimensional structure unique to each type of protein. The covalent linkage between two adjacent amino acids in a protein (or polypeptide) chain is called a peptide bond. There are twenty amino acids that make up proteins. Each amino acid has a typical
Harold Urey proposed a series of conditions, which, if present on prebiotic Earth, would have been conducive to the origins of life on Earth. Stanley Miller later proved that these conditions were favorable for the synthesis of simple amino acids, which was the beginning of a series of experiments, modeled on this notion of prebiotic Earth, that created other more complex molecules needed to support life. Using the hypothesis set up by Urey and tested by Miller, this paper looks at whether
The definition of macromolecule is- A large complex molecule, such as nucleic acids, proteins, carbohydrates, and lipids, with relatively large molecular weight. In biology, a macromolecule is a term used to contrast a macromolecule (which is smaller in size and in molecular weight). Macromolecules are usually used to refer to large biological polymers, such as nucleic acids and proteins, which are made up of small monomers linked together. Macromolecules are made of ten thousand or more atoms. Macromolecules
three fatty acids and one molecule of glycerol, or alcohol. Waxes are composed of a long fatty acid chain and an alcohol chain. Steroids are made of four carbon rings, and are found in asthma medications and venoms from many poisionous creatures. 13. What are the main elements found in proteins? Proteins are made up from the elements Carbon, Hydrogen, Oxygen, and Nitrogen, or C,H,O,N. 14. The elements form compounds that are the monomers of proteins. These monomers are called amino acids and have
the organic molecules which form living matter. Organic compounds are important for life and they include small monomers, as well as macromolecules, also called polymers. Some organic molecules even include carbohydrates, proteins, lipids, and nucleic acids which are the essentials for life processes. The chemical reactions that build up organic compounds are called Dehydration Synthesis or Condensation Reaction. Dehydration synthesis is a chemical reaction that builds up molecules by losing water
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
that are covalently bound together. Explanation All forms of life are composed only of biomolecules. For example, humans have skin and hair. The main part of hair is keratin , an agglomeration of proteins which are themselves polymersbuilt from amino acids. Characteristics of Biomolecules: Organic compounds and they have particular shapes and proportions. Chemical properties are determined by functional group and mostly asymmetric. They are composed of small building blocks and have planar structure
carbohydrates, proteins, nucleic acids, and lipids. These 4 classes or groups are essential to the function and structure of a cell along with life itself. These molecules are all organic which means that they all contain carbon, they also might have oxygen, hydrogen, nitrogen, and other elements within the molecules. Macromolecules are formed through dehydration synthesis which starts with single subunits called monomers. These monomers, amino acids, sugars, nucleotides, glycerol, fatty acids, and etc. combine
They are formed through polymerization. Polymerization occurs when smaller molecules (monomers) join together to create larger molecules (polymers). Macromolecules are sorted by their chemical composition into the groups: carbohydrates, lipids, nucleic acids and proteins all of which are essential for living things to. The carbohydrates and lipids are needed for energy. But, carbohydrates are the main source of energy for living things, while, lipids mainly stores the energy. Proteins are used to build
When approaching the topic of hair chemistry, one may think about the question, where does hair come from? Saclike holes called follicles are located all over the human body. At the bottom of these follicles are a cluster of papilla responsible for the growth of hair. As the papilla, otherwise known as hair bulbs reproduce to make new hair cells, the old ones are pushed up towards the surface of the skin causing the hair to grow longer. This may seem like a simple concept to grasp. However, the process
of soda, is sodium bicarbonate. (Baker Bettie, 2013) Sodium bicarbonate has a high pH, that when incorporated with another acid will react quickly. Although carbon dioxide, is created when baking soda is combined with an acid with low pH. Baking soda will make cookies rise during the baking process, once it reacts with an acid. There must be a common acid (examples of acids are: buttermilk, sour cream, citrus juice, vinegar, and cream of tartar) added to the recipe to produce CO2 if the baking soda
As you may know, when you mix baking soda and vinegar there is a big reaction, but have you ever wondered how this reaction happens? Well in order to find out how it happens you will need to know the elements that make up baking soda and vinegar. You will also learn why these elements are where they are on the periodic table and what is released during the baking soda and vinegar reaction. Baking soda is made out of sodium, carbon, and 2 oxygens while vinegar is made up of 4 hydrogens, 3 carbons
Boats and motorized watercraft are great for a fun day on the lake, but how fun are they for the diverse ecosystems living just beneath the hull of your boat? Boat exhaust and small traces of gasoline and oil are emitted into the waters when motorized watercraft are running. Boats have been shown to affect water clarity and can be a source of algal growth in aquatic ecosystems. The toxins emitted from boats can add chemicals to the water. Certain amounts of the fuel that is in motors is discharged
products can be acidic, bases or neutral. It was very interesting to learn that many acids are not dangerous. Some are even found in the food that we eat. Any food that taste sour is acidic. Bases are also found in common household products. They can be very strong and dangerous or weak and safer for use around the house. 2. INVESTIGATIVE QUESTION To prove how much acidic levels are in our household products and foods ACID BASE NEUTRAL Coffee Ammonia Olive Oil Lemon Juice Baking Soda Melted Butter Soda
1. Definition of Acid and Bases: 1.1 Arrhenius definition of acid and base: Arrhenius Acid: The substance or a compound which gives H+ ions in aqueous solution Arrhenius base: Base is a substance or compound that produces OH- ions in aqueous solutions. Chemists have known for some time that the H+ ion doesn’t exist in aqueous solutions as an independent species. The modernized Arrhenius definition of acid is that they are substances that produce H3O+ ions in aqueous solutions. It did not take longer
