Digestive Enzyme

Digestive enzyme is a general term for enzymes involved in digestion. The role of general digestive enzymes is hydrolysis; some are secreted in the digestive gland, and some involved in the intracellular digestion. Among extracellular digestive enzymes, some are secreted in forms of inactivating enzymes such as pepsinogen, trypsin, procarboxypeptidase and be reactivated.

What is Enzyme

Enzyme, also known as ferment, is a protein with a catalytic function in the organism. The salient features of the enzyme are highly catalytic function and specificity, and its activity can be adjusted, and it is closely related to different forms of energy transformation. Up to now, the known enzymes have reached nearly 2000. Digestive enzyme is one of them, which can promote digestion mainly secreted by the digestive gland and digestive system. And digestive enzymes can be roughly divided into protease, amylase, lipase and cellulase, and so on according to the different objects.

The action principle of digestive enzymes

The digestive function of the human body depends on the mechanical digestion of gastrointestinal motility and the chemical digestion of digestive enzymes. Digestive juice contains abundant digestive enzymes, which can promote the hydrolysis of sugar, fat and protein in food. Large molecules turn into small molecules in order to be absorbed by the human body. Glucose, glycerol, glycerol ester, amino acid and so on are soluble small molecular substances, which can be absorbed by the small intestine. In the clinical, the deficiency of digestive enzyme will cause a wide range of dyspepsia symptoms group, such as flatulence, stomach full swelling, nausea, abdominal pain, diarrhea, anorexia, affecting the digestion and absorption of nutrients, resulting in hyperlipidemia, fatty diarrhea, fat soluble vitamin deficiency, endocrine disorders and other.

The major pathogenesis of the lack of digestive enzymes are: chronic pancreatitis, gallstones, liver cirrhosis, liver dysfunction, pancreatic cancer, chronic gastrointestinal disease, pancreatectomy, excisions of stomach and gall bladder, side reaction of radiotherapy or chemotherapy, senile digestion hypothyroidism, long-term drinking. The formation mechanism of the symptoms of indigestion is extremely complicated, and the hyposecretion of digestive enzyme or functional decline is a considerable reason for the production of digestive symptoms.
