Structure, properties and classification of amino acids

Some key-words are:
What is the structure ?
What is the role of Proteins?

  1. The function of a protein is intrinsically dependent on its structure.
  2. Since its structure is maintained by combinations of chemical interactions which are individually weak and flexible, the environment in which a protein finds itself can affect its structure.
  3. Heat and pH affect protein structure.
  4. The cell uses factors such as phosphorylation or ligand-binding to affect the structure, and therefore the function, of many proteins
Amino Acid
  1. The first discovered Amino Acid was asparagine, in 1806.
  2. The last, threonine, 1938.
  3. All the amino acids have trivial or common names, in some cases derived from the source from which they were first isolated.
  4. Asparagine was first found in asparagus,
  5. Glutamate in wheat gluten;
  6. Tyrosine was first isolated from cheese (its name is derived from the Greek tyros, “cheese”); and glycine (Greek glykos, “sweet”) was so named because of its sweet taste.
Essential Amino acids: They are not synthesized by the body and must be supplied from the diet. These are; Isoleucine, Leucine, Lysine, Methionine, Phenylanine, Threonine, Tryptophan, Valine, Arginine*, and Histidine*
