Question
Define the following terms in relation to proteins:
- Peptide linkage.
- Denaturation.
✓
Answer
- Peptide linkage: Peptide linkage is an amide $\ce{(-CO-NH-)}$ bond formed between $–\text{COOH}$ and $–\ce{NH_2}$ group in protein formation.
- Denaturation: When a protein in its native form, is subjected to physical change like change in temperature or chemical change like change in $\ce{pH},$ protein loses its biological activity. This is called denaturation of protein.
