1932 American scientist King first isolated vitamin C (ascorbic acid)
April 4, 1932 American biochemist Charles Glen King first isolated vitamin C. This vitamin is very important for the life of the human body. It plays a major role in the formation of collagen, which is necessary for the growth and restoration of cells of tissue, gums, blood vessels, bones and teeth, and promotes the assimilation of iron by the body.
The existence of such substances as vitamins, scientists guessed long before the discovery of King. As early as 1880, the Russian biologist Nikolai Lunin from Tartu University conducted a series of experiments on mice in this direction and in his thesis concluded that there is some unknown substance necessary for life in small quantities. At that time Lunin's conclusion was skeptically accepted by the scientific community.
In 1927, Hungarian biochemist Albert Sainte-Gyouri singled out a substance which, as King subsequently proved, was necessary for the body to prevent scurvy. After five years of painstaking research, King extracted from lemon juice this substance, later called vitamin C.
The structural formula of this vitamin was quickly identified, and in 1933 the scientists Howard and Reinstein synthesized it. Vitamin C or ascorbic acid is a colorless, transparent, water-soluble vitamin found in citrus fruits, some berries and green vegetables. Most organisms synthesize it from glucose, but a person can not do this and must get it with food.
For a person, vitamin C is very important. It helps to heal wounds, reduce cholesterol, protect against infections, prevent the appearance of blood clots. The need for vitamin C increases with illness, stress, exposure to toxic effects. Vitamin is involved in the development of vital chemicals, helps to cleanse the body of poisons. Also, scientists came to the conclusion that the lack of vitamin C speeds up the aging of the body.
