Enzymes are named for what they do. For example, the enzyme given off by the stomach, which splits proteins as part of the digestion process, is called gastric proteinase. The “gastric” part of the name refers to the enzyme's origin in the stomach. The “proteinase” denotes that it splits up protein molecules. The common name for this enzyme is pepsin. Similarly, the enzyme produced by the pancreas that breaks down fats (lipids) is called pancreatic lipase. Its common name is steapsin. In general, lipase enzymes cause lipid triglycerides to dissociate and form glycerol and fatty acids.

The hydrolysis of fat is carried out by lipases. Lipases perform an essential role in the digestion, transport, and processing of dietary lipids. Human pancreatic lipases convert triglycerides into monoglycerides and two fatty acids. Lipases are also produced from bacteria and fungus. The application of lipases is wide and they can easily be produced in large quantity; hence it is an industrially very demanding enzyme (Table 14.4).

Inhibition of pancreatic lipase (PL), a major enzyme in fat absorption, is thought to be a promising treatment for obesity. The hydrolysis of triacylglycerides in the gastrointestinal tract is catalyzed by PL. It hydrolyzes 50–70% of total dietary lipids. The in vitro PL inhibitory activity of PE-SNPs was estimated using a colorimetric technique that quantifies p-nitrophenol release (Sajjad et al. 2021). The application of PE-SNPs resulted in the inhibition of 32.5–89.8% of enzyme activity (Table 4), where D-SNPs, DL-SNPs, and R-SNPs showed significant inhibition of pancreatic lipase. Surface functional groups found on PE-SNPs may be responsible for their anti-lipase action, which could lead to the development of new anti-obesity lipase inhibitor treatments.
