✦ Synopsis
Intermediate water structures in a solution of N "-acetyl-N-methylphenylalaninamide[Phe(an~ide~~l were investigated by the energy minimization method. The results show that ninety-eight water molecules hydrate Phe(amideIz and several kinds of cyclic structures are observed. The distribution of water molecules around Phe(amide)z agrees with the results of molecular dynamics and monte carlo studies. The distribution of cyclic structures shows that the six-membered ones are distributed mainly at the outside of the first hydration shell.

Observations on 40 known a-amino acetylated polypeptide chains reveal characteristic properties. Types of residues in the acetylated position are limited, with serine and alanine in about three quarters of all cases. The distribution is different (P < 0.001) from that of N-terminal residues in prote
