According to Kaplan the answer is glycine b/c it has the least steric hinderance. The Kaplan book states that only proline is an α-helix breaker. HOWEVER, according to Khan Academy and google, BOTH glycine and proline are α-helix breakers and glycine is often not found in α-helices because it's too flexible.

Hydrogen bonds form between N-H group of one amino residue with C=O group of another amino acid, which is placed in 4 residues earlier. Beta Pleated Sheet: Hydrogen bonds are formed in between the neighboring N-H and C=O groups of adjacent peptide chains. Unlike the α-helix, which features intramolecular hydrogen bonds over 13 atoms in a right- or left-handed, helix contingent on l - or d-amino acid stereochemistry, respectively (Figure 2), the regular alternation of d - and l-amino acids, possessing primary amines, in a linear peptide leads typically to a helical, conformation, in which two anti-parallel helices form a cylindrical, shape When proline is found in an α helix, the helix will have a slight bend due to the lack of the hydrogen bond.

A predictive rule for protein folding is presented that involves two recurrent glycine-based motifs that cap the carboxyl termini of alpha helices. In proteins, helices that terminated in glycine residues were found predominantly in one of these two motifs. These glycine structures had a characteristic pattern of polar and apolar residues. Visual inspection of known helical sequences was A predictive rule for protein folding is presented that involves two recurrent glycine-based motifs that cap the carboxyl termini of alpha helices.

Glycine and alanine can combine together with the elimination of a molecule of exact pattern of them is different in an alpha-helix and a beta-pleated sheet.

There is, however, considerable controversy about the relative values for alanine and glycine. We find from experiments on mutants of barnase that the relative effect of Ala versus Gly on helix stability depends crucially on the position in the helix (whether they are Answer to The amino acid glycine can be found inBeta sheets.Right handed alpha helix.Right handed and left handed alpha helix.Righ Interestingly, glycine, like proline is not usually found in an alpha helix, but for the opposite reason.

The α-helix is a common protein secondary structure unit. In an ideal α-helix, a network of hydrogen bonds forms between each amide backbone carboxyl oxygen and the i + 4 amino hydrogen, such that one turn occurs every 3.6 residues. These helices can assemble into CCs, which are characterized by the supercoiling of the helices around each other (often likened to the strands of a rope).

This is an introductory question so I’m giving an introductory answer; if you’d like more details just ask. An alpha helix is essentially a perfect spiral. Every piece in the spiral has to form a peptide bond and twist at the proper angle. Furthermore, glycine alters H-bond occupancies and triggers a redistribution of α-helical and 310-helical H-bonds. These effects facilitate local helix bending at the glycine site and change the collective dynamics of the helix.
