The stability of the collagen triple helix depends partly on the repetitive sequence of amino acids that comprise the individual alpha helices. Which of the following amino acids most likely faces the center of the collagen triple helix? - AnsGlycine The most stable structure for the collagen triple helix will likely feature the amino acid with the least sterically-hindered functional group facing the center of the helix; as such, glycine, whose functional group is a mere hydrogen ato...
