What role does bile play in food digestion?

Bile promotes food digestion.

The gallbladder is the main organ that stores bile, which plays an important role in the digestion of food, the decomposition of fats, and the absorption of nutrients. In addition, the gallbladder also has a good control and regulation effect on the secretion of bile. Whenever a meal is eaten, the gallbladder will continuously secrete bile into the gastrointestinal tract to promote food digestion and facilitate the absorption of nutrients.

Bile acids can combine with fatty acids to form water-soluble complexes to facilitate the absorption of fatty acids. In addition, bile is also important for promoting the absorption of fat-soluble vitamins (vitamins A, D, E, K). Bile neutralizes some of the stomach acid in the duodenum, and it is also a humoral factor that promotes the secretion of bile itself.

Without bile, the stomach would not dare to digest.

It is secreted into the stomach to balance stomach acid and help digest grains.

Hehe, this one is very simple. Hand hit you well.

Bile is mainly used to digest fats, and if you eat a lot of fatty meat, then bile is used to break down fats.

Therefore, those with gallbladder problems, such as cholecystitis, cannot eat meat.

Bile has on fats.

Emulsifying. Disperse the fat into smaller particles or.

Droplet. Therefore, adding bile to raise laughing residue shakes well, and mixing oil and bile is more noisy and even, and adding water can not be mixed evenly.

Bile is a bitter, colored liquid juice that is constantly produced by liver cells. Hepatic bile is weakly alkaline (pH 7 4) and gallbladder bile is weakly acidic (pH 6 8) due to bicarbonate absorption. In addition to water, bile also has bile pigments, bile salts, cholesterol, lecithin, fatty acids, inorganic salts and other components.

There are no digestive enzymes in bile, but bile plays an important role in the decoarization and absorption of fats. The bile salts in bile are sodium or potassium salts that are combined with glycine or taurine by bile acids secreted by the liver. The role of bile is mainly that of bile salts.

1) Bile salts can activate pancreatic lipase, which accelerates the catalytic lipolysis of the latter.

2) Bile salts, cholesterol and phosphatidylcholine (lecithin) in bile can be used as oral emulsifiers to emulsify fat into fine particles, increase the area of pancreatic lipase, and increase its decomposition of fat.

3) Bile salts and fat decomposition products such as free fatty acids, monoacylglycerol (monoglyceride) and other products will form water-soluble complexes, which promote the absorption of fats.

4) By promoting the absorption of fat, it indirectly helps the absorption of fat-soluble vitamins (vitamins A, D, E, K).

5) It is the main way for cholesterol and bile pigment metabolites to be excreted from the body.

The main components of bile are bile salts, cholesterol, bile pigments, lecithin and a variety of inorganic salts. The main digestive component of bile is bile salts. Bile salts, cholesterol and lecithin can reduce the surface tension of fat, so that fat emulsification into many microdroplets, in order to increase the area of pancreatic lipase, which is conducive to the digestion of fat; Bile salts can also be combined with fatty acids, monoglycerides, etc., to form water-soluble complexes, promote the absorption of fat digestion products, and can promote the absorption of fat-soluble vitamins (vitamins A, D, E, K).

Although bile does not contain digestive enzymes, it is important for the digestion and absorption of fats.
