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
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
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
enzyme is responsible for its catalytic activities. Therefore, enzymes are proteins made of amino acids. This essay further points out the features of enzymes that accounts for why, they are made of proteins, not other macromolecules. Macromolecules are large molecules formed by polymerization of smaller molecules. The four classes of macromolecules are Carbohydrates, lipids, proteins and nucleic acid. Carbohydrates are made of carbon, hydrogen and, and Oxygen, the simplest form of carbohydrates
the arrangements, functions and interactions of biological macromolecules, such as proteins, nucleic acids, carbohydrates and lipids, which make up the structure of cells and carry out many of the functions related with life. The chemistry of the cell also rests on on the reactions of smaller molecules and ions. These can be inorganic, for instance water and metal ions, or organic, for example the amino acids which are used to manufacture proteins. The instruments by which cells harness energy from
Thiosulphate and Nitric Acid Planning Aim The aim of this investigation is to find out and observe how the temperature affects the rate of reaction. I am going to investigate the rate at which the solutions of nitric acid (HNO³) and sodium thiosulphate (Na²S²O³) turn cloudy (when mixed together), when the temperature is changed. Variables In this investigation I will only have one variable: § The temperature of both solutions (sodium thiosulphate and Nitric acid), so that I will
Liquid Liquid Extraction We were asked to extract benzoic acid from a kerosene-benzoic acid mixture. This was to be done using the stirred liquid-liquid extraction column in the senior laboratory. Fresh water was used as the continuous phase in the extraction. We were asked to measure the benzoic acid concentrations of the feed, raffinate, and extract streams. These measurements were to be made at several different steady-states. The number of theoretical stages and the height of the theoretical

The acidity or alkalinity level is dictated by the pH, potential of hydrogen, scale. Soil pH or soil reaction is an implication of the acidity or alkalinity of soil and is measured in pH units. Soil pH is characterized as the negative logarithm of the hydrogen particle fixation. As the measure of hydrogen particles in the soil builds the soil pH diminishes along these lines getting to be more acidic. From pH 7 to 0 the soil is progressively more acidic and from pH 7 to 14 the soil is progressively
