D-CALCIUM PANTOTHENATE
Introduce briefly Calcium pantothenate is a kind of B vitamin and one of the essential nutrients for the normal growth of organisms. Calcium pantothenate exists in three forms because it has chiral carbon atoms: D L-body (hybrate), D-body (right-body) and L-body (left body). Only D-calcium pantothenate has biological activity, with a white or slightly yellow needle-shaped crystal or powder in appearance, and a melting point of 195~196 ℃ (decomposition), Soluble in water, methanol, glycer... -
INOSITOL
Introduce briefly Inositol, also known as cyclohexanol, hexahydroxycyclohexane, cyclohexylitol, meat muscle sugar, and non-spin inositol, belongs to one of the B vitamins. Due to the different orientation of the relative ring plane of the hydroxyl group, there are a total of 9 isomers, of which 7 are non-spins and 2 are spins (levorot and dextros). It exists in all biological tissues in the form of free or combined in nature. It is a common component in animal and plant cells. It can be ... -
BIOTIN
Introduce briefly Biotin is eight forms of water-soluble vitamins, also known as vitamin B7. It is a coenzyme or coenzyme used in many metabolic reactions in the body. Biotin participates in lipid and protein metabolism, helping to convert food into glucose, which can be used by the human body as energy. It is also important for maintaining the skin, hair and mucous membranes. Chemical properties Colourless to white crystalline or crystalline powder. Melting point 230-232℃. Soluble ... -
Vitamin A
Introduce briefly Vitamin A includes vitamins A1 and A2. Vitamins A1 and A2 are similar in structure) Retinol can be synthesised from plant-derived beta-carotene. Under the catalysis of β-carotene-15, 15′-peroxide (bioxygenase) in the body, β-carotene can be converted into two molecules of retinaldehyde (ratinal), and retinaldehyde in reductase It is reduced to retinol under the action of. Therefore, beta-carotene is also known as vitamin A. Chemical properties Vitamin A is a ... -
VITAMIN B1
Introduction Vitamin B1, also known as “thiamine” and “thiamine”, is one of the B vitamins. It can promote normal glucose metabolism and is a necessary substance to maintain the normal function of nerve conduction, heart and gastrointestinal tract. It combines with adenosine triphosphate to form vitamin B1 pyrophosphate (thiamine diphosphate, that is, coenzyme), which is a necessary coenzyme for carbohydrates to replace Chemicalbook. Chemical properties Vitam... -
VITAMIN B2
Introduction Vitamin B2 is also known as riboflavin It is a water-soluble vitamin that the human body cannot synthesise by itself and must be supplied by food. It is indispensable for maintaining the normal physiological function and metabolism of the human body. Vitamin B2 participates in the normal growth of cells, promotes wound healing, strengthens nails and hair, and is also an important component of coenzymes. It participates in the synthesis and metabolism of carbon Chemicalbook w... -
VITAMIN B6
Introduction Vitamin B6 is rapidly converted into pyridoxaldehyde phosphate in the human body. This compound plays an important role in amino acid metabolism and is a coenzyme of decarboxylase, transaminase, canine urease, deaminase and desulphurisation hydrase. It is also a coenzyme necessary for carbohydrate and fat metabolism, the activity of the central nervous system and the production of red eggs. Chemical properties The chemical properties are relatively stable and more stabl... -
CYANOCOBALAMIN (VITAMIN B12)
Shape and Properties This product is a crimson crystal or crystalline powder, odourless, tasteless and has strong moisture-inducing properties. Slightly soluble in water or ethanol, insoluble in chloroform or ether. Heat-resistant, but it can be ineffective when exposed to oxidising or reducing substances, heavy metal salts and strong acids and strong alkalis. Chemical Structure Vitamin B12 is an equioctaphedral compound containing cobalt ions. Its central structure is a flat corrin... -
ASCORBIC ACID
Introduction Vitamin C, also known as L-ascorbic acid, is a high-level Essential nutrients for long animals and a few other organisms. Ascorbic acid can be produced by metabolism in most organisms, but humans are the most obvious exceptions. The most widely known thing is that lack of vitamin C in Chemicalbook can cause scurvy. The pharmacokidic group of vitamin C is ascorbic acid ion. In the body, vitamin C is an antioxidant because it can protect the body from the threat of oxidising a... -
VITAMIN D3
Introduction Vitamin D3, also known as cholesterol, is a kind of vitamin D, which has been proven It is the real active form of vitamin D in the body. At present, there are at least 10 known types of vitamin D, but the most important are vitamin D2 and vitamin ChemicalbookD3 . Cholecalciferol, also known as vitamin D3, is the most important form of vitamin D, which mainly regulates the metabolism of calcium and phosphorus in the body. Vitamin D3 is converted from 7-dehydrogenated cholest... -
VITAMIN E
Introduction Vitamin E, also known as tocopherol, is an antioxidant and nutritional agent with excellent performance. At the same time, it has the characteristics of high biological activity and safe eating. It is widely used in medicine, health care products, food, cosmetics and other fields. Physicochemical properties Vitamin E is A slightly yellow to yellow or yellow-green clarified viscous liquid, almost odourless, and the colour gradually darkens when exposed to light. The natu... -
NICOTINAMIDE
Introduction Niacinamide, also known as nicotinamide, vitamin B3 or vitamin PP, is a water-soluble vitamin and belongs to B vitamins. The niacinamide part in these two coenzyme structures in the human body has the properties of adding Chemicalbook hydrogen and dehydrogenation, which plays a role in biological oxidation. Hydrogen transmission can promote tissue respiration, biological oxidation process and metabolism, which is of great significance for maintaining the integrity of normal ...
