The Physiological Functions Of Chromium

wallpapers News 2020-12-29
Chromium symbol Cr, silver-white metal, belongs to group VIB in the periodic table. Chromium has an atomic number of 24 and an atomic weight of 51.9961. It is a body-centered cubic crystal. The common valences are +3, +6 and +2. The oxidation number is 10. In 1797, French chemist L.N.Vauquelin discovered a new element in Siberian red lead ore (chrome-lead ore) and reduced it with carbon the following year to obtain metallic chromium. Because chromium can generate beautiful multi-colored compounds, it is named chromium according to the Greek word chroma (color).
 
The physiological functions of chromium mainly include:
 
1. An important component of glucose tolerance factor (GTF) in the body: GTF is an active compound composed of trivalent chromium, niacin, glutamic acid, glycine and sulfur-containing amino acids, which can enhance the biological effects of insulin , Can accelerate the utilization of glucose in the body by activating glucose phosphate mutase, and promote the conversion of glucose into fat.

 
2. Affect lipid metabolism: Chromium can inhibit cholesterol biosynthesis, reduce serum total cholesterol and triacylglycerol content and increase high-density lipoprotein cholesterol content. The elderly are prone to diabetes and atherosclerosis when they are deficient in chromium.
 
3. Promote protein metabolism and growth and development: Chromium has a high content in nucleoprotein. Studies have found that it can promote the synthesis of RNA. Chromium also affects the transport of amino acids in the body. When the intake of chromium is insufficient, growth retardation may occur in experimental animals.
Normal healthy adults lose about 1 microgram of chromium in urine every day.
 
Brewer's yeast, waste molasses, cheese, eggs, liver, apple peel, banana, beef, flour, chicken, and potatoes are the main sources of chromium.
 
To be precise, the physiological function of chromium is to cooperate with other substances that control metabolism, such as hormones, insulin, various enzymes, and cellular genetic materials (DNA and RNA).
