Pure gastric juice is a colorless liquid, sometimes slightly opalescent, with lumps of mucus.It contains hydrochloric acid, enzymes, minerals, gastrin hormone mucus traces of organic compounds. Gastric juice is acidic.
major component of gastric juice, which is produced by the parietal cells of fundic glands of the stomach, - hydrochloric acid.
It maintains a certain level of acidity in the stomach and prevents the penetration of pathogens into the body and prepares the food to the efficient hydrolysis.Hydrochloric acid has a constant and unwavering concentration - 160 mg / dL.
Digestion begins in the mouth.Enzymes saliva - maltase and amylase - are involved in the breakdown of polysaccharides.Bolus into the stomach where gastric using approximately 30-40% digestible carbohydrates, by exposure hydrochloric acid alka
bicarbonate gastric juice are used to neutralize the hydrochloric acid at the surface of the gastric mucosa and duodenal ulcers and protect the mucosa from acid.
bicarbonate concentration in the gastric juice - 45 mmol / l.
Mucus Mucus contains bicarbonates and protects the mucous membrane of the hydrochloric acid and pepsin. is produced in the stomach additional surface cells.
main enzyme contained in gastric juice by which splits proteins.Medicine familiar with several isoforms pepsin, each of which participates in the cleavage of a single type of protein.
lipase enzyme, which is in the gastric juice in a small amount.It performs the function of the initial hydrolysis of fat splitting them into fatty acids and glycerol.The lipase is a surface active catalyst as the other enzymes of the gastric juice.
enzyme, which is part of the gastric juice, translates inactive form of vitamin B12, which enters the stomach with food, the active.It is produced by the parietal cells of the gastric glands.
