COMMENTS
These are the 20 standard human amino acids; humans have hydroxyproline as a 21st amino acid, but only in collagen. - Jonathan Vos Post, Feb 22 2009
The order in which these were discovered is given by Pert, p.65, as N, C, L, G, Y, D, A, V, S, E, F, R, K, H, P, W, hydroxyproline, I, M, T. - Jonathan Vos Post, Apr 30 2013
