Macrolipase formation
WebThis type includes the macroenzymes formed by serum enzyme (or more frequently particular isoenzyme) linking with specific immunoglobulins, mostly IgG and IgA class, and less frequently IgM class. The reason for the formation of the enzyme-immunoglobulin complexes remains unknown. WebLipase (E.C.3.1.1.3) belongs to the hydrolases and is also known as fat splitting, glycerol ester hydrolase or triacylglycerol acylhydrolase. Lipase catalyzes the hydrolysis of …
