Definition: The word "acetaldehydrase" is a specific enzyme found in the liver that catalyzes the conversion of acetyl-CoA (an amino acid) to乙酰辅酶 A (甘油三酯, also known as triglycerides). This process occurs during the production of fatty acids from fat-soluble nutrients and is an important biochemical pathway in the body. The enzyme activity of acetaldehydrase increases with age due to a reduction in the synthesis capacity of other enzymes that catalyze this process. In young individuals, it has been shown to be absent or reduced during certain conditions, such as malnutrition or liver failure, indicating potential dysfunction in this particular pathway. Acetaldehydrase also plays a crucial role in fatty acid metabolism and energy production. It is involved in the synthesis of beta-oxidation products like acetyl-CoA, which are essential for the breakdown of fats into fatty acids and ketones. In addition, it helps to regenerate fatty acids from glycerol using an enzyme called carboxyase. Overall, the activity of acetaldehydrase plays a crucial role in regulating cholesterol metabolism and energy production within the body and is known as "the liver's main source of triglycerides" (a type of fat).
