Question: Antibiotic resistance is a growing problem. The antibiotic Vancomycin binds via hydrogen bonding to D-ala-D-ala which is part of an intermediate in Bacterial cell wall

Antibiotic resistance is a growing problem. The antibiotic Vancomycin binds via hydrogen bonding to D-ala-D-ala which is part of an intermediate in Bacterial cell wall Biosynthesis. Please indicate all possible hydrogen bond acceptor and donor sites on D-Ala-D-Ala below (Note that D-Ala is just the enantiomer of the naturally occurring amino acid L-Ala.) . H HON OH . Bacteria have gain resistance to vancomycin, e.g.vancomycin resistant enteroccoci (VRE), by changing D-Ala-D-Ala to D-Ala-D-Lac where D-lac is D-lactate. Please indicate all possible hydrogen bond acceptor and donor sites on D-Ala-D-Lac below CH HEN OH o CH3
