Amino acids They are the constituents of proteins, have an amino group of (-NH2) and a carboxyl group (-COOH) bonded to the same asymmetrical carbon, known as the alpha carbon. 20 amino acids are commonly found in proteins, each identified by the variable side chain [R group] bonded to the alpha carbon. Glycine: simpliest amino acid [H as R group] and alanine has a methyl (-CH3) group. They have a neutral pH and are mainly dipolar ions. –COOH donates a proton [-COO`]

Unformatted text preview: and NH2 accepts a proton [-NH3`] Amino acids classified as having nonpolar side chains tend to have hydrophobic properties; polar has hydrophilic properties. Essential amino acids are those an animal cannot synthesize in amounts sufficient to meet its needs and must obtain from the diet. Different essential amino acids for diff animals....
