Collagen is the most abundant protein in animal world.

Ligases are the enzymes catalysing the linking together of two compounds, e.g., enzymes which catalyse the joining of C - O, C - S, C - N, P - O, etc. bonds.

When the inhibitor closely resembles the substrate in its molecular structure and inhibits the activity of the enzyme, it is known as a competitive inhibitor.

Lactose is a disaccharide which is made up of galactose and glucose.
