Lipase is an enzyme produced in the pancreas, mouth, and stomach that breaks down fats in food. It breaks down triglycerides into fatty acids and glycerol by catalyzing the hydrolysis of ester bonds in triglycerides. Lipases are present in pancreatic secretions and participate in fat digestion and metabolism, playing an essential role in lipid transport and individual functions in several tissues. The document describes how to retrieve the amino acid sequence of lipase from the NCBI database and use software tools Protoparam and Swiss Model to analyze the sequence and generate a 3D model of the lipase protein structure.
