BIOCHEMISTRY: LS2101 Dr. Partha P. Datta IISER Kolkata 1 AMINO ACIDS, PEPTIDES, AND PROTEINS chiral center 2 enantiomers absolute configuration 3 4 5 Amino Acids Can Be Classified by R Group 6 7 8 9 Amino Acids Can Act as Acids and Bases Proton Donor Proton Acceptor 10 Substances having this dual nature are amphoteric and are often called ampholytes 11 Amino Acids Have Characteristic Titration Curves Titration Curves Predict the Electric Charge of Amino Acids The characteristic pH at which the net electric charge is zero is called the isoelectric point or isoelectric pH, designated pI. For glycine, which has no ionizable group in its side chain, the isoelectric point is simply the arithmetic mean of the two pKa values: 12 Peptides 13 14 15 16 17 18 19 20 21 22 23 24
