The formation of cholesterol in the human body mainly involves biosynthesis and food intake.
1. Biosynthesis: The biosynthesis in the body is mainly made of glucose as raw material, glucose undergoes aerobic oxidation to form acetyl COA, acetyl COA under the action of acetyl acetyl COA sulfurylase, acetyl acetyl COA under the action of HMGCOA synthetase to form HMGCOA, and HMGCOA under the action of HMGCOA reductase to form cholesterol finally.
2. Food intake: Cream, animal offal, eggs and other substances contain a lot of cholesterol, intake of these foods can accumulate a certain amount of cholesterol in the body.
If a large amount of cholesterol accumulates in the body, it will easily cause atherosclerosis, fatty liver and other diseases. Therefore, avoid excessive intake of food containing sugar and cholesterol.
