Denaturing proteins
Discovered in 1838, proteins are recognized as a large number of superior organic compounds that make up living organisms and are essential for their functioning. In other words proteins are the building blocks of life. They do many tasks for the human body and other organisms, that could not be done individually. These macromolecules could function as structural proteins and form structures such as keratin in hair, teeth, bones, muscles, collagen in connective tissues, horns in animals and even silk in spider webs. Just like they can structure they can also function as storage proteins, transport proteins, defensive proteins and enzymes. Storage proteins provide long term storage such as casein in milk as well as it can be a last-ditch source of energy during a starvation period for the body after carbohydrates and fats are used up. Transport proteins regulate particular activities in the body like sending and receiving signals between cells, while another could be oxygen-carrying hemoglobin in red blood cells. Defensive proteins provide protection against foreign substances that enter the bodies of organisms and antibodies protect from disease and protect the body from harmful microorganisms. Enzymes regulate the rate of chemical reactions in cells and control metabolism. there is many different types of proteins so they are required for almost every essential function in organisms. A protein is composed of the elements carbon, hydrogen, oxygen, nitrogen and sometimes phosphate and sulfur. Since proteins have a function they also have a complex structure. When proteins are formed, the biomolecule goes through four levels of structure, primary, secondary, tertiary and quaternary. The primary structure is where the unique sequence of amino acids that was brought in from the nucleus to the ribosome, are bonded by peptide bonds creating a polypeptide chain. A polypeptide is the polymer that is composed of the monomers amino acids. There is a

    A Macromolecule is a molecule with a very large number of atoms .The word macromolecule is usually used for describing polymers. Molecules that are made up of smaller molecules are called monomers, there are also Organic Molecules composed of carbon atoms .The functions of the Four big Macromolecules: First, Carbohydrates, carbohydrates is the function of being used for energy production during cellular respiration. Second , Lipids, lipids are used for four things; insulation and long-term energy storage, being a primary component of cell membranes, hormonal functioning, and help control the fluidity of cell membranes, Also lipids or fats are composed of fatty acids . Third, Nucleic Acid, the functions of nucleic acid is storing genetic material, transferring genetic information called DNA and RNA to ribosomes for protein synthesis, that carries Amino acids into place and Polypeptide keeps the chain of amino acids together ,also DNA is composed of nucleotides ,and holds ribosomal subunits together, Deoxyribose replaces hydroxyl in groups . Four, Protein, The functions of proteins are structural support in things such as hair and nails, protection against germs, and bodily movements. Carbohydrates are…

    A). The chemical composition and structure of proteins seems quite confusing at first but one it is broken down into levels it is much more understandable. Amino acids are the basic building blocks of proteins and they contain amino, carboxyl and R groups. These R groups that are in the amino acids are what determine the properties of the specific amino acids. For structure, there are 4 levels. The first one being the primary level. These are made up of sequences of amino acids and these amino acids are linked together by peptide bonds. The next level is called secondary. This level is a formation of amino acid chains folded together by a helix formation or a pleated sheet. The bonds between…

    Proteins are complex molecules that each has a very unique shape, structure and function. The shape of the proteins is held up by a chain of subunits called amino acids that are connected by peptide bonds. Protein structures are formed by four levels of folding. The primary structure is the linear sequence of amino acids. The secondary structure describes the folding of alpha helixes and beta pleated sheets. The tertiary structure represents the overall shape of the protein and the quaternary structure only occurs in a protein consisting of more than one amino acid chain. When the shape, the structure or the function of proteins is incorrect, it is likely because of some type of change in the sequence of the amino acids or whether a certain amino acid required is present.…

    Proteins are made up of groups of twenty different amino acids. In the average adult, twelve of those acids are made in the body, and the other eight we have to ingest through our food. Those eight are called the essential amino acids. Amino acids cannot be stored in the body, so we need to eat foods regularly that contain the essential amino acids. We get most of our high quality proteins from meat and dairy products (Trefil & Hazen, 2013).…
