According to the paper, F486 is a phenylalanine residue (i.e., an amino acid that is part of a chain that forms a protein) on SARS-CoV-2. It has an important interaction with ACE2 (best seen in Fig. 1(C) and Fig. 2(A)). Looking at this phenylalanine and the green residues surrounding it, which statement best describes the interaction that could be occurring? a) It forms a hydrogen bond with Y83. b) It forms a dipole-dipole interaction with M82. c) It forms London dispersion forces with surrounding residues. d) It encounters repulsions from surrounding residues.
Aspartame (Nutrasweet®) is a remarkably sweet-tasting dipeptide ester. Complete hydrolysis of aspartame gives phenylalanine, aspartic acid, and methanol. Mild incubation with carboxypeptidase has no effect on aspartame. Treatment ofaspartame with phenyl isothiocyanate, followed by mild hydrolysis, gives the phenylthiohydantoin of aspartic acid.Propose a structure for aspartame.
Brucine is a poisonous alkaloid obtained from Strychnos nux vomica, a tree that grows in India, Sri Lanka, and northern Australia. Write out a resolution scheme, which shows how a racemic mixture of phenylalanine can be resolved using brucine.
Bradykinin is a linear nonapeptide released by blood plasma globulin in response to a wasp sting. It is a very potent pain-causing agent. Its constituent amino acids are 2R, G, 2F, 3P, S. The sue of 2,4-dinitrofluorobenzene and carboxypeptidase shows that both terminal residues are arginine. Partial hydrolysis of bradykinin gives the following di- and tripeptides: FS + PGF +PP + SPF + FR + RP
