Acid Lipase A is an important enzyme involved in lipid metabolism and the breakdown of fats in the body. Synonyms for Acid Lipase A include LIPA, LAL, and lysosomal acid lipase. This enzyme plays a crucial role in breaking down triglycerides and cholesterol esters that are stored in lipid droplets within cells. Mutations in the gene encoding Acid Lipase A can lead to a rare genetic disorder known as lysosomal acid lipase deficiency (LAL-D), which results in the accumulation of lipids and subsequent organ damage. Acid Lipase A and its synonyms are vital in maintaining optimal lipid balance in the body and any dysregulation can have severe consequences.
