BICH 410 Lecture Notes - Lecture 6: Optical Rotation, Stereocenter, Dipeptide
Document Summary
Two amino acids with more than one stereocenter = ile & thr *** Fischer convention help with determining the chirality and name of certain amino acids. Cystein sul de group is reactive in order to form a disul de bond (sh - sh) Unusual amino acids can be important components of proteins and peptides or play a metabolic role. Within proteins, there are speci c modi cations that these amino acids go under. Amino acids and their derivatives sometimes function in non protein roles in cells. Two amino acids condense to form a dipeptide releasing water (condensation reaction) Polypeptides have multiple ionizable groups which affect their overall structure and chemical properties. *proteins can shift their pka within their structure. Figure out which groups are contributing to the overall pka of the entire compound pi is based on the charge of. Monomeric - proteins composed of one polypeptide chain. Both function properly even though put in different lengths.
