  • Protein - 399 Words
    Introduction: Proteins are necklaces of amino acids – long chains molecules. Proteins are the basis of how biology get this done. As enzymes, they are the driving force behind all the biochemical reactions which make biology work. As structural elements, they are main constituents of our bones, muscles, hair, skin, and blood vessels. As antibodies, they recognize invading elements and allow the immune system to get rid of the unwanted invaders. For these reasons, scientists have sequenced...

  • Denaturation of Proteins - 3000 Words
    “Denaturation of Proteins” Denaturation is a process in which proteins or nucleic acids lose the tertiary structure and secondary structure which is present in their native state, by application of some external stress or compound such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), or heat. If proteins in a living cell are denatured, this results in disruption of cell activity and possibly cell death. Denatured...

  • Denaturation of Proteins - 647 Words
    Denaturation of proteins involves the disruption and possible destruction of both the secondary and tertiary structures. Since denaturation reactions are not strong enough to break the peptide bonds, the primary structure (sequence of amino acids) remains the same after a denaturation process. Denaturation disrupts the normal alpha-helix and beta sheets in a protein and uncoils it into a random shape. Denaturation occurs because the bonding interactions responsible for the secondary structure...

Amino acids are made up from carbon, hydrogen, oxygen, nitrogen and sometimes sulphur. They have a two-carbon bond. One of the carbon's is part of a group called the carboxyl group. A carboxyl group is made up of one carbon (C) and two oxygen (O) atoms. That carboxyl group has a negative charge, since it is a carboxylic acid that has lost its hydrogen (H) atom.

    Protein Essay- Erin Keegan What are proteins? A polypeptide is a chain of monomers joined up to make a polymer. Proteins are organic polypeptides made up of a chain of amino acid residues- they’re residues because they lose a water molecule. The amino acids (monomers) join up by forming peptide bonds. When two amino acids join together, they become a dipeptide. This happens when the carboxyl group of an amino acid and the amino group of another amino acid link up through a condensation reaction...

    Carbohydrates have two major functions in plants and animals: they serve as fuel and building material. Plants store most of their energy in the form of starch. Starch is a polysaccharide (consisting of several conjoined sugars). Synthesizing starch enables the plant to stockpile surplus glucose, and since glucose is a major cellular fuel, starch represents stored energy. The sugar can later be withdrawn by hydrolysis, which breaks the bonds between monomers. Animals, in turn, have enzymes...

    Protein Article Research Proteins are a part of each cell, tissue, and organs (CDC, 2012). We break down and replace proteins; this means that foods that we consume must contain protein in order for us to replace the needed protein. There are quite a few types of proteins that we can find in every day diets. Proteins are made up of amino acids (CDC, 2012), and we know that there are about twenty various amino acids that make up different types of protein. Essential amino acids are vital to...
