Question

What is meant by peptide linkage and biocatalysts?

Answer 1

(i) A peptide linkage is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water $\left(H_{2}O\right)$. This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids.

(ii) Biocatalyst can be defined as the natural substances that initiates or modifies the chemical reaction rates in living systems. The natural substances can be one or more enzymes or cells. An enzyme is simply a protein catalyst.
