A2 Amino Acid Stereochemistry

The amino acids are all chiral with the exception of glycine whose side chain is H As with lipids biochemists use the L and D nomenclature All naturally occurring proteins from all living organisms consist of L amino acids The absolute stereochemistry is related to L-glyceraldehyde as was the case for triacylglycerides and phospholipids

Nonbiological amino acid

amino acid any of a class of organic compounds containing the amino (NH 2) and the carboxyl (COOH) groups occurring naturally in plant and animal tissues and forming the chief constituents of protein Twenty amino acids are necessary for protein synthesis Eleven (the nonessential amino acids) can be synthesized by the human body and thus are not specifically required in the diet: alanine

Amino Acid Analysis

Amino acid analysis is used to determine the amino acid content of amino acid– peptide‐ and protein‐containing samples With minor exceptions proteins are long linear polymers of amino acids connected to each other via peptide bonds The first step of amino acid analysis involves hydrolyzing these peptide bonds

Amino acid size charge hydropathy indices and matrices

22 03 2006Amino acid MW varies between 57 (Gly) and 186 (Trp) or between 1 and 130 if only the weight of the residue is counted (-56 for the peptide backbone) This gives an average R weight ~61 5 or ~123 for average residue pairs The deviation of a given amino acid pair from this average residue weight (RW) is calculated using the equation

Amino Acids

Amino acids with an amide on the side chain do not produce basic solutions i e asparagine and glutamine Neutral Side Chains: Since an amino acid has both an amine and acid group which have been neutralized in the zwitterion the amino acid is neutral unless there is an extra acid or base on the side chain If neither is present then then the
