The electrophoretic mobilities of liposomes prepared from egg phosphatidylcholine (PC) immersed in solutions which contain amino acids, polypeptides or proteins have been studied. Amino acids (lysine — a basic amino acid, or glutamic acid — an acidic amino acid) cause a pH variation which changes...

Chemical Nature of the Amino Acids All peptides and polypeptides are polymers of alpha-amino acids. There are 20 a-amino acids that are relevant to the make-up of mammalian proteins (see below). Several other amino acids are found in the body free or in combined states (i.e. not ...
