2, sugar and protein in food, if intake exceeds consumption, will also be converted into fatty acids, further synthesis of fat, stored in the form of fat. How to consume: Fat cells release fat (triglycerides) very slowly even during exercise. In the process of dissociation, exercise or the lack of energy in the body will stimulate the secretion of a lipolytic enzyme, which will react with hormones to decompose fat and produce three fatty acid molecules and one glycerol. This process is called lipolysis. Glycerol produced is water-soluble and will dissolve in blood. In the process of fat hydrolysis stimulated by exercise, the most important hormones are adrenocortical hormone and paraadrenocortical hormone. Exercise can increase the concentration of fatty acids in the blood. During long-term moderate-intensity exercise, the fatty acid oxidation rate is 10 times that of normal exercise, and the fat synthesis rate also slows down. So doing more aerobic exercise can reduce fat content. Most of the fat ingested by human body is emulsified into small particles by bile. Lipases secreted by pancreas and small intestine hydrolyze fatty acids in fat into free fatty acids and monoglycerides (occasionally completely hydrolyzed into glycerol and fatty acids). Hydrolyzed small molecules, such as glycerol, short and medium chain fatty acids, are absorbed into the blood by the small intestine. After monoglycerides and long-chain fatty acids are absorbed, triglycerides are first synthesized in small intestinal cells, and form chylomicrons with phospholipids, cholesterol and protein, which enter the blood circulation from the lymphatic system. Note: Liver cells can synthesize fat, but they cannot store fat. After synthesis, it should be combined with apolipoprotein and cholesterol. To form very low density lipoprotein, which will be transported to extrahepatic tissues for storage or utilization. If the triglycerides synthesized by the liver cannot be transported in time, fatty liver will be formed.
