Question

What is the difference in hydrogen bonding between an $\alpha$ helix and a $\beta$-pleated sheet?

Short answer

In the a-helix structure the hydrogen bond is formed between the oxygen atom of the carbonyl group $(\mathrm{C}=\mathrm{O})$and the hydrogen of the amine group $(\mathrm{N}-\mathrm{H})$in the next turn of the helical chain.

In $\beta$-plated sheet the hydrogen bond is formed between the oxygen atom of the carbonyl group $(C=O)$and the hydrogen of the amine group$(N-H)$in the parallel section of polypeptide chain.

Step-by-step solution

Introduction 

Amino acids have amine$\left(-{\mathrm{NH}}_2\right)$and carboxylic acid $(-\mathrm{COOH})$ functional groups. The a-carbon is covalently bonded to both functional groups.

Explanation 

Amino acids comprise an amine$\left(-{\mathrm{NH}}_2\right)$and carboxylic acid $(-\mathrm{COOH})$ functional organization. Both the useful agencies are covalently bonded to the $\alpha -$-carbon. Amino acids are the constructing blocks for all proteins.

A dipeptide identityentification fashioned while amino acids go through a response wherein an amide bond is fashioned among the amine organization of 1 amino acid and to the carboxylic organization of different amino acids and that joins the 2 amino acids.

Proteins are macromolecules made from repeating subunits called amino acids, which decide form and characteristics of protein.
