CHEM160 Module 3-4 Amino acids, Peptides, Proteins, and Enzyme Kinetics
Amino Acids • Building blocks of proteins. • Naturally occurring amino acids have an amino group (NH2) bonded to the α-carbon of a carboxy group (COOH), and so they are called a-amino acids. • The 20 standard amino acids differ in the structures of their side chains (R groups) Voet - Fundamentals of Biochemistry [5e].p.81; Smith - Organic Chemistry [5e].p.1153 R-group = side chain
General Features of the a-Amino acids • All L-amino acid except from glycine and cysteine have the S configuration. Smith - Organic Chemistry [5e].p1153
