Discuss the function of lipoprotein lipase and hormone sensitive lipase. Make a table.
Understand the Problem
The question is asking for a discussion about the functions of two specific enzymes: lipoprotein lipase and hormone-sensitive lipase. It also requests that the information be organized in a table format. This indicates a request for a comparative analysis of the two lipases and their roles in lipid metabolism.
Answer
LPL hydrolyzes circulating triglycerides, facilitating tissue uptake. HSL mobilizes stored fats within adipose tissues.
Lipoprotein lipase (LPL) functions to hydrolyze triglycerides into free fatty acids and glycerol for tissue uptake, primarily affecting circulating triglyceride-rich lipoproteins. Hormone-sensitive lipase (HSL) hydrolyzes stored triacylglycerol, diacylglycerol, and cholesterol esters in adipose tissues, mobilizing fatty acids during fasting or stress.
Answer for screen readers
Lipoprotein lipase (LPL) functions to hydrolyze triglycerides into free fatty acids and glycerol for tissue uptake, primarily affecting circulating triglyceride-rich lipoproteins. Hormone-sensitive lipase (HSL) hydrolyzes stored triacylglycerol, diacylglycerol, and cholesterol esters in adipose tissues, mobilizing fatty acids during fasting or stress.
More Information
LPL and HSL serve critical roles in lipid metabolism, managing the levels of fatty acids used by different tissues. LPL is often found in the circulatory system interacting with lipoproteins, whereas HSL functions more intracellularly within fat storage cells.
Tips
Confusing LPL and HSL functions in triglyceride metabolism is common. Remember, LPL works on circulating particles, while HSL targets stored fats.
