Answer 1

Collagen is a protein made of three identical polypeptides composed primarily of α helix structure. The α helix is an example of a (3) secondary structure stabilized by hydrogen bonds.

Collagen is a protein found in the human body in bones, tissues, skin, etc. It is very essential for the body as it increases the muscle mass, prevents the bone loss, relieves joint pain, and improves skin health. The most important properties of collagen are its rigidity and resistance to stretching.

Hydrogen bonds are the non-covalent bonds that are a most important part of various chemical structures. These are one of the strongest bonds. The hydrogen atom (electropositive) of one molecule is attached to the electronegative atom of the other molecule that could be fluorine, oxygen or nitrogen.
