Vitamin C is one of the varieties ascorbic acid and plays an important redox role in the body. Without its participation, the full functioning of the immune system is impossible.
The body becomes defenseless against infectious agents. The processes of metabolism, blood clotting and tissue regeneration are disrupted. It makes it difficult to absorb other vitamins.

special instructions
Wikipedia states that vitamin C (L-ascorbic acid) is related to glucose organic compound. Its benefits for the human body are enormous - the vitamin functions as a coenzyme of the metabolic processes, antioxidant and reducing agent.
According to the International Pharmacopoeia, the substance appears as a crystalline powder, almost white or white with a sour taste. Easily soluble in water, soluble in ethanol (approximately 750 g/l) TS, practically insoluble in other organic solvents, the powder is practically insoluble. Belongs to the category of antiscorbutic drugs.
Vitamin C in solution it quickly collapses when exposed to air; Even in a light-protected place, it gradually collapses in a humid atmosphere. The rate of destruction increases with increasing temperature.
Ascorbic acid is present in all tissues of higher plants and animals. Man, unlike most animals, in the process of evolution due to mutation, lost the ability to independently synthesize vitamin C , and receives it exclusively from food.
OKPD code for ascorbic acid ( vitamin C ) - 24.41.51.180. For Food Industry the substance is obtained in accordance with GOST 4815-76.
Quantitative determination of a substance
Methods quantification A.k. based on its pronounced restorative properties.
The simplest, objective and accurate method is the determination method based on the ability of A.K. reduce ferric ions into ferrous ions.
The amount of Fe2+ ions formed is equimolar to the amount of A.c. in the analyzed sample (the minimum amount of A.C. in the sample is 10 nmol) and is determined by the color reaction with potassium iron sulfide.
What is ascorbic acid needed for?
The substance participates in the processes of biotransformation of other , education , as well as education and exchange And norepinephrine in the medulla adrenal glands , supplies hydrogen for the formation of nuclear DNA, reduces the body’s need for B vitamins , increases the body’s immunobiological resistance, affects activity leukocytes ; improving the absorption of Fe, thereby enhancing the synthesis hemoglobin and maturation red blood cells , neutralizes toxins released by pathogenic microflora, accelerates wound healing and postoperative sutures and healing of fractures.
Ascorbic acid in urine is important indicator health of the body. Small amount vitamin C in urine may indicate disturbances in the functioning of internal organs or the development tumor process.
