Question

Which of the following statements is FALSE? A)Both -helices and -sheets have R groups that are oriented away from the core of the structure. B)Both -helices and -sheets are stabilized by hydrogen bonds between groups in the polypeptide backbone. C)Both -helices and -sheets have conformations that minimize steric strain in the polypeptide backbone. D)Both -helices and -sheets form only from adjacent (sequential) amino acid residues in the polypeptide.

Answer 1

A)Both -helices and -sheets have R groups that are oriented away from the core of the structure.

True, they both have R.groups

B)Both -helices and -sheets are stabilized by hydrogen bonds between groups in the polypeptide backbone.

This is true, H-bonds add stabilizaiton

C)Both -helices and -sheets have conformations that minimize steric strain in the polypeptide backbone.

true, they make the polyupeptide steric

D)Both -helices and -sheets form only from adjacent (sequential) amino acid residues in the polypeptide.

false, only helices
