What is a peptide bond?
A peptide bond is a chemical bond that forms between the amino group (NH2) of one amino acid and the carboxyl group (COOH) of another amino acid during the process of protein synthesis. Peptide bonds are covalent bonds, which means that they involve the sharing of electrons between atoms. The formation of a peptide bond occurs through a dehydration or condensation reaction, which involves the removal of a water molecule (H2O). Here's how it happens: Two amino acids are positio

What is cellulose in biology?
Cellulose is a polymer made up of glucose molecules.Carbon, hydrogen and oxygen atoms are found in the cellulose polymer.It is a polysaccharide found abundantly in nature. Chiefly found in the cell wall of the plant cell. Cellulose provides turgidity to the plant cell and helps in maintaining the shape of the plant intact.The primary cell wall of the plant has cellulose. It is biodegradable in nature and does not have any taste. Cellulase is the enzyme used by the organism to digest t

Which part of a lipid molecule is hydrophilic in nature?
The polar head (or phosphate group) of a phospholipid molecule is hydrophilic (water-loving). It contains charged or polar functional groups that interact favorably with aqueous environments, while the fatty acid tails are hydrophobic (water-repelling).
