Synthesis of palmitate — Fat Palmitic acid is one of the most prevalent fatty acids occurring in the oils and fats of animals; it also occurs naturally in palm oil. It is generated through the addition of an acetyl group to multiple malonyl groups connected by single bonds between carbons. This structure forms a saturated acid—a major component of solid glycerides.

Pancreatic lipase is a critical enzyme responsible for the digestion of dietary fats in the small intestine.12

Its primary role involves the hydrolysis of triglycerides, which are composed of three fatty acid chains attached to a glycerol framework. Pancreatic lipase acts on these molecules by splitting off two of the three fatty acid chains, resulting in the formation of a monoglyceride and free fatty acids.2

Because bile salts can inhibit this activity, the pancreatic enzyme colipase is required to bind to bile salts, thereby allowing lipase to access and break down the triglycerides. The resulting products—monoglycerides and fatty acids—are then incorporated into micelles, which are essential for transporting these fat components across the "unstirred" fluid layer to the intestinal mucosa for absorption. Through this process, pancreatic lipase facilitates the conversion of insoluble dietary fats into forms that can be absorbed and utilized by the body.21
