Lipase 77 was shown to hydrolyze p-Nitrophenyl esters of butyrate and triglycerides.

Lipase from *Candida antarctica* is an enzyme-based biocatalyst, which is derived from the yeast *Candida antarctica*. This enzyme operates via a catalytic mechanism that involves the hydrolysis of ester bonds in lipid substrates, thereby facilitating the breakdown of fats into glycerol and free fatty acids. Its catalytic efficiency and stability in various conditions make it highly versatile for industrial applications.

Aspartic acid proteinase is a type of proteolytic enzyme, which originates from various biological sources including humans, fungi, and plants. It is characterized by its action via two critical aspartic acid residues in the active site, which facilitate the hydrolysis of peptide bonds in proteins. This enzyme operates optimally in acidic environments, making it crucial in processes like digestion and protein processing within cellular compartments such as lysosomes.
