Question

an alpha helix is a structural feature of
a. sucrose
b. polypeptides \
c. nucleotide
d. starch

Answer 1

Answer:

Correct Option is :

(b). Polypeptides

Explanation:

In secondary structure of Proteins, a polypeptide chain exists in two forms :

1). Alpha helix

2). Beta pleated sheet.

Answer 2

Answer:

An alpha helix is a structural feature of polypeptides i.e.option(b).

Explanation:

• The polypeptides of amino acids are proteins.
• Because of the varied ways that amino acids are arranged, proteins have unique structures.
• Covalent connections in a linear series of amino acids bound by peptide bonds make up the protein's fundamental structure.
• Alpha helix is a form of secondary folding of a protein.
• The -NH group of each amino acid residue makes a hydrogen bond with the -CO- of a neighboring turn of the helix, forming one of the most frequent routes for a polypeptide chain to form all potential hydrogen bonds.

So, an alpha helix is a structural feature of polypeptides i.e.option(b).
