Question

describe what do you understand by primary structure and secondary structure of proteins​

Answer 1

Answer:

1. Proteins structures are made by condensation of amino acids forming peptide bonds. The sequence of amino acids in a protein is called its primary structure. The secondary structure is determined by the dihedral angles of the peptide bonds, the tertiary structure by the folding of proteins chains in space

Answer 2

Answer:

Primary structure : The sequence in which amino acids are arranged in a polypeptide chain of a protein is called its primary structure.

Secondary structure : The confirmation which the polypeptide chain of a protein molecule required due to the secondary bonding such as hydrogen bonding between the carbonyl and amino group is called the secondary structure of protein.

The $\alpha -helix$ and $\beta -pleated$ sheet structures are the common examples secondary structure of proteins.
