The structure and hydrogen bond of tert‐butoxycarbonyl‐D, L‐isoleucyl‐glycyl methyl ester

The structure and hydrogen bond of tert‐butoxycarbonyl‐D, L‐isoleucyl‐glycyl methyl ester The crystal structure of tert‐butoxycarbonyl‐D, L‐isoleucyl‐glycyl methyl ester was determined by the X‐ray method. The space group is P21 with a = 9.115(3), b= 12.075(4), c = 16.258(5) Å, β = 89.84(3) and Z = 4. It was observed that in the peptides which contain IleGly fragment the carbonyl group of Gly residue has less tendency to form hydrogen bond than that of Ile residue. This tendency was supported by the atomic net charges calculated with the quantum mechanics program CNDO/2. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Chinese Journal of Chemistry Wiley

Abstract

The crystal structure of tert‐butoxycarbonyl‐D, L‐isoleucyl‐glycyl methyl ester was determined by the X‐ray method. The space group is P21 with a = 9.115(3), b= 12.075(4), c = 16.258(5) Å, β = 89.84(3) and Z = 4. It was observed that in the peptides which contain IleGly fragment the carbonyl group of Gly residue has less tendency to form hydrogen bond than that of Ile residue. This tendency was supported by the atomic net charges calculated with the quantum mechanics program CNDO/2.
