Vitamin B5

Description:

Vitamin B5, also known as pantothenic acid, is a water-soluble vitamin with the chemical formula C9H17NO5, and is named "pantothenic acid" because it is widely found in plants and animals. Since all foods contain vitamin B5, there is almost no deficiency problem. 

Vitamin B5 can be used as hair color auxiliaries in the food industry, and adding 0.01~0.022g per kilogram of meat can make the meat color good. Also used in bread, pastry, dairy products as food fortifier. In the feed industry as a vitamin additive, added to poultry, pigs, young ruminants, fish and other feed. In cosmetics, it plays a role in protecting and improving rough skin. 

Application：

Vitamin B5 has the chemical formula C9H17NO5 and is optically active, with only type D ([α]=+37.5°) being biologically active. Racemic vitamin B5 has hygroscopicity and electrostatic absorption. Pure free vitamin B5 is a yellowish viscous oil, acidic, soluble in water and ethanol, but insoluble in benzene and chloroform. Vitamin B5 is unstable under conditions of acid, alkali, light and heat. 

Vitamin B5 is present in almost all living cells and can be synthesized by enzymatic reactions in the cells of prokaryotes, fungi, molds and plants. Organisms can also transport vitamin B5 into cells via Na+ -dependent multivitamin transporters (SMVT, also known as pantothenic permease). 

Feature

Vitamin B5 is converted into Coenzyme A (CoA) or acyl carrier protein (ACP) in the body to participate in fatty acid metabolism. CoA is a cofactor for more than 70 enzymes in living organisms (about 4% of the total enzyme volume), and bacteria also need CoA to build their cell walls. In metabolism, CoA mainly plays the function of acyl carrier, participating in sugar, fat, protein and energy metabolism, and can also affect protein localization, stability and activity by modifying proteins. CoA provides 90% of the energy of living organisms. 

Vitamin B5 is essential for fatty acid anabolic steroids; It can also participate in the synthesis of steroids purpurin, melatonin and heme. It is also an intermediate necessary for metabolism such as citric acid cycle, choline acetylation, and synthesis of antibodies in the body. Therefore, vitamin B5 can act on normal epithelial organs such as nerves, adrenal glands, digestive tract and skin in the body to improve the animal's resistance to pathogens. Vitamin B5 may also increase glutathione biosynthesis to slow cell apoptosis and damage. Experiments have shown that vitamin B5 has a good protective effect on cells and rats that have been damaged by lipid peroxidation. Pantothenyl mercaptoethylamine can lower cholesterol and triglyceride concentrations. Vitamin B5 and its derivatives can also reduce the toxic side effects caused by antibiotics and other drugs, and participate in the absorption and utilization of a variety of nutrients.
