- For each of the following, name an amino acid in which the R group contains it: a hydroxyl group, a sulfur atom, a second chiral carbon atom, an amino group, an amide group, an acid group, an aromatic ring, and a branched side chain.A pentapeptide has a titration curve that shows five inflection points for five equivalents of hydroxide added. How many residues have ionizable groups within their side chains (R-groups) based on this information?Draw the condensed structural formula for a monounsaturated omega-3 fatty acid with 12 carbon atoms
- The pKa of the side-chain imidazole group of histidine is 6.0. What is the ratio of uncharged to charged side chains at a pH of 7.4?Draw the structure of the omega-6 fatty acid 16:1.Olestra has been used in certain snack foods as an alternative to fats and oils. Its structure consists of a sucrose molecule in which all free hydroxyl groups have formed esters with oleic acid (an 18-carbon monounsaturated fatty acid). Olestra molecules have no caloric value because they are exceptionally large and cannot be digested. Draw the structure of olestra. Use R-COOH as an abbreviation for oleic acid.
- How many chiral carbons are present in this amino acid (aqueous form)? (Identify the following amino acid (at pH = 7.0): (COO-)–CH(NH3+)–CH2–CH2–CH2–CH2–(NH3+)) zero chiral carbons one chiral carbon two chiral carbons three chiral carbons four chiral carbonsWhich of the following define the stereochemistry of alanine (as per the structure shown)?
