Vitamin B2 was originally isolated from whey and named Lacto Flavin.
Riboflavin is widely distributed in nature. It is synthesized by many plants, yeasts, lower fungi, and some bacteria. The gastrointestinal tract of many animals and humans contains bacteria that produce riboflavin, but in small quantities. Losses of Vitamin B2 during the thermal and culinary processing of foodstuffs are insignificant if they are protected from light exposure. The vitamin is well preserved during pasteurization, sterilization and freezing of foodstuffs.
A person should receive Riboflavin regularly through food.
ACTION
The biological role of Riboflavin is determined primarily by its participation:
In the redox reactions of metabolism in the body;
The most important catalyst for cellular respiration processes,
Is involved in carbohydrate, protein and fat metabolism.
Vitamin B2 is part of visual purple, protecting the retina from UV radiation. Riboflavin is involved in providing light and color vision (along with vitamin A), increases dark adaptation and visual acuity. Riboflavin plays an important role in iron metabolism. With its deficiency, the development of hypochromic microcytic anemia is possible.
The need for Riboflavin depends on the total energy consumption, increases with increased physical activity.
SYMPTOMS OF HIPOVITAMINOSIS.
The main reasons for the lack of Riboflavin are:
Insufficient consumption of milk and dairy products
As well as diseases of the gastrointestinal tract and taking medications – Riboflavin antagonists (for example, quinacrine)
The provision of the body with Vitamin B2 is judged by its amount in the urine, as well as in the blood serum.
The most common symptoms of Vitamin B2 deficiency are: Changes in the mucous membranes of the mouth, skin, and eyes. The earliest symptom is damage to the mucous membrane of the lips.
SING OF VITAMIN DEFICIENCY RIBOFLAVIN:
Dryness and bluishness of the lips,
Vertical cracks on the lips (cheilosis)
Cracks and crusts in the corners of the mouth
Dry bright red tongue
Seborrheic dermatitis of the face, ears, neck
Conjunctivitis, blepharitis
With the aggravation of the deficiency, swallowing difficulties, dryness of the mucous membrane of the pharynx and esophagus, dysphagia can be observed. On the part of the organ of vision – violations of light and color sensitivity. Violations of the synthesis of hemoglobin.
Riboflavin deficiency can cause growth retardation in infants. B2 deficiency increases with burns, which is associated with increased protein breakdown.
