Question

Peptide bond is present in
a. Carbohydrates
b. Proteins
c. Lipids
d. Nucleic acids

Answer 1

Answer is (b) Peptide is a protein.

A peptide bond is a covalent type chemical bond which links two consecutive acid monomers along a  protein long chain.

Peptide bond requires energy for existence , which, in living systems for its formation and existence.

It is extracted from ATP. 

The chains containing Polypeptides and proteins of amino acids held together by peptide bonds.

Living organisms release enzymes to form polypeptides, and ribosomes also needs to generate protein.

Peptides are synthesized by specific enzymes.
