Our production of blood collection additives, biological buffers, chromogenic substrates, chemiluminescent substrates, enzyme preparations and antigen antibodies all belong to biochemical reagents. Although we seldom hear about them, in fact, the commonly used vitamins also belong to the category of biochemical reagents. Vitamin is a kind of micro organic substance that human and animal must obtain from food to maintain normal physiological function, and it plays an important role in the process of human growth, metabolism and development. Vitamins are neither involved in the formation of human cells nor provide energy for the human body.
Vitamin A, an unsaturated monohydric alcohol, is a fat soluble vitamin, also known as anti dry eye alcohol. It is known that there are two kinds of A1 and A2. A1 exists in the liver, blood and retina of eyeball, also known as retinol. Natural vitamin A mainly exists in this form. A2 is mainly found in the liver of freshwater fish. The difference between A2 and A1 is only that there is a double bond at 3.4 of β - angelinone ring. In the blood, retinol (R) combines with retinol binding protein (RBP) and plasma prealbumin (PA) to form r-rbp-pa complex and transport it to various tissues.
There are many vitamins B, such as thiamine, riboflavin B2, niacin B3, pantothenic acid B5, pyridoxine B6, folic acid B9, cobalamin B12, inositol b-h.
Vitamin C, ascorbic acid, water-soluble, mostly in fresh vegetables and fruits.
Vitamin D, calciferol, also known as ossifying alcohol, anti rickets vitamin, mainly including vitamin D2, ergocalcitol and vitamin D3, cholecalciferol. This is the only vitamin that the human body can synthesize in small amounts. It mainly exists in cod liver oil, egg yolk, dairy products and yeast.
Vitamin E, tocopherol fat soluble. There are mainly four kinds: α, β, γ, δ. It mainly exists in eggs, liver, fish and vegetable oil.
Vitamin H, i.e. biotin or coenzyme R, is water soluble. Most of them are yeast, liver and grain.
Vitamin K, naphthoquinones, fat soluble. It is a general term for a series of naphthoquinone derivatives, mainly including natural vitamin K1 from plants, vitamin K2 from animals, and synthetic vitamin K3 and vitamin K4. Also known as coagulation vitamins. It mainly exists in spinach, alfalfa, cabbage and liver.
Since 2005, Desheng technology has developed and produced in vitro diagnostic reagents, such as separation gel, heparin, EDTA potassium salt, etc. it has a deep research on new Trinder's reagents, bicine, Tris and luminol, acridine ester and other biobuffers such as chromogenic substrate TOS, Maos, etc., and has a professional advantage in independent research and development and synthesis.
