Triacylglycerol lipase function
WebJan 19, 2024 · The in-house determination of triacylglycerol lipase activity is based on the hydrolysis of triglycerides in olive oil. The enzymatic activity is determined by the back titration of the released free fatty acids from the olive oil emulsion with hydrochloric acid in an excess of sodium hydroxide (reaction conditions: pH 7.0, 37°C, 10 min).

WebMolecular structure of triglycerides (fats) Triglycerides, or fats, are formed from the combination of glycerol and three fatty acid molecules. Triglycerides are formed through dehydration reactions. Another word for triglyceride is triacylglycerol. Fats can be solid (such as coconut oil) or liquid (such as vegetable oil) at room temperature. The main function of hormone-sensitive lipase is to mobilize stored fats. HSL functions to hydrolyze either a fatty acid from a triacylglycerol molecule, freeing a fatty acid and diglyceride, or a fatty acid from a diacylglycerol molecule, freeing a fatty acid and monoglyceride. This process allows energy metabolism in mammals. Although Hormone-Sensitive Lipase (HSL) is able to catalyze hydrolysis of triglycerides and diglycerides, another enzyme found in adipose tissue, Adi…
