Phospholipases D belong to the family of esterases and act on phosphatidylcholine in the plasma membrane to release phosphatidic acid (PA) and choline. Phospholipases D can be used as versatile tools in hydrolysis and transphosphatidylation reactions for industrial, chemical and food applications. The Phospholipase D Kit contains 4 enzymes with a broad pH range for transphosphatidylation activity.

Lipases belong to the family of esterases and naturally act on triglycerides at lipid-water interfaces. Lipases/esterases can be used as versatile tools in hydrolytic reactions, esterifications and transesterification reactions in industrial and food applications. The Lipase kit contains 25 lipases with different pH and temperature optima and substrate specificity properties.

Neuron-specific enolase human (ENO2, Enolase 2, Neural enolase, Gamma-enolase, Phosphopyruvate hydratase, 2-phospho-D-glycerate hydro-lyase; EC 4.2.1.11) is the enzyme that is catalyzes the following reaction:  2-phospho-D-glycerate ⇌ phosphoenolpyruvate + H2O  One unit of enolase will convert 1.0 μmole of 2-phosphoglycerate to phosphoenolpyruvate per min.

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.
