Yes, lipase is a protein.
Lipases are a family of enzymes that catalyze the hydrolysis of fats (lipids). Enzymes, by definition, are biological catalysts, and virtually all enzymes are proteins. Lipases have a characteristic tertiary structure composed of two domains: a large N-terminal domain and a smaller C-terminal domain, linked by a hinge region. This structure is typical of proteins.
Lipases play crucial roles in digestion, fat metabolism, and cellular signaling. Their protein structure enables them to bind to specific lipid substrates and perform their catalytic function efficiently.
