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...

High molecular weight proteins are separated both in denatured and active configuration states. In this chapter an arbitrary distinction is made between the low molecular weight peptides (<20,000 Da) and the high molecular weight proteins. Both the kinetic and chemical behavior of the polypeptides ...
Chains of amino acids linked in this manner are thus called polypeptides or, more simply, proteins. Sign in to download full-size image Figure 2. The 20 common amino acids. Three- and one-letter abbreviations and the composition of the ‘R’ side chain group are shown. Asterisks indicate ...
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 ...
Almost twenty years ago Sutherland (1952) reviewed the subject of infrared analysis of the structure of amino acids, polypeptides, and proteins. Gore (1954), Jones and Sandorfy (1956), Bellamy (1958), and Rao (1963) have more recently reviewed work on amino acids and related substances. ...
