A major stabilizing factor in the triple helix is a ____ structure such that ____ residues from the three strands stack along the center of the triple helix.
A) linear, glu
B) linear, gly
C) staggered, lys
D) staggered, gly
E) stacked, pro

Question

Quizplus · Accepted Answer

The major stabilizing factor in the triple helix is a staggered structure, where glycine (Gly) residues from the three strands stack along the center of the triple helix. Glycine is the smallest amino acid and its small side chain allows it to pack tightly in the center of the triple helix. The other options (A, B, C, and E) are incorrect because they either describe the wrong type of structure or the wrong type of residue involved in the stabilization.
