This image has the same problems as its labeled version, namely the amine group in the glycine that should be a hydroxyl group and the upper cysteine that should be a methionine, that I mentioned on the talk page of its labeled version. — Preceding unsigned comment was added by 50.235.102.246 (talk) 16:37, 19 March 2018 (UTC)
- Neither of those issues is an error. The C-terminal end is correctly drawn as glycinamide, a modification of glycine. Also, there is no reason that every peptide must have a methionine at the N-terminus. In oxytocin, the N-terminal amino acid is cysteine. Ed (Edgar181) 22:44, 19 March 2018 (UTC)
