Intestinal microflora

The importance of the microflora of the human digestive system. List of functions of microflora, without which human health is impossible:

1. Stimulation of immune activity;
2. Antagonistic action against foreign bacteria due to synthesis colicins, alcohols, hydrogen peroxide, lactic and other acids, fatty acids;
3. Increased assimilation of Fe, Ca, vitamin D (due to the creation of an acidic environment);
4. The destruction of the excess of digestive secretions - enterokinase and phosphatase;
5. Participation in metabolism:

• convert choline into tetramethylamine; bilirubin - in urobilin;
• decompose proteins to indole, skatole and phenol - resulting in improved
  peristalsis;
• synthesize 9 vitamins - pyridoxine, riboflavin, nicotinic and
  pantothenic acid, cyanocobalamin (B12), vitamin K. Biotin, folic acid
  acid and thiamine provide the body with almost 100%;
• synthesize essential amino acids and vitamins, promote education
  leukocytes;
  cause activation of thyroid function (affect gas exchange) and
  increased renewal of cells of the intestinal mucosa;
• fix nitrogen of air and promote protein synthesis;
• synthesize or convert cholesterol into components (sterbilin,
  coprosterol, desoxycholic and lithocholic acids), depending on the need
  organism;
• affect the absorption of water from the intestine - increase absorption.

  Weight of microflora is 2.5 - 3 kg.
