Also known as biotin, is the necessary material of the synthesis of vitamin C, is an indispensable material for fat and protein metabolism. According to biotin supplier, human need about 100 to 300 micrograms daily.
Raw eggs have a avidin can combine with biotin, combined with biotin can not be absorbed by the digestive tract; causing animal biotin deficiency, appears to loss of appetite, glossitis, dander, dermatitis, hair removal and so on. However, there are not see cases of human biotin deficiency, may be due to the addition to the food source, intestinal bacteria can also synthesize biotin. Biotin is a coenzyme for a variety of enzymes in the human body, involved in the body's metabolism of fatty acids and carbohydrates; promote protein synthesis; also involved in vitamin B12, folate (folic acid food), pantothenic acid metabolism; to promote urea synthesis and excretion.
Constitute a photosensitive substance, vitamin H, in vivo oxidation generated cis-retinal and retinoic aldehyde. There are two photosensitive cells within the human retina, wherein the rod cells to low light sensitive, and related to the dark vision, because the rod cells containing a rhodopsin substance of the photosensitive substance, which is composed of visually egg cells cis retinaldehyde. Lack of vitamin H when not enough supplementary cis-retinal rod cells can not synthesize enough rhodopsin cells, and thus cause night blindness.
Vitamin H is a necessary material maintaining the body's epithelial integrity. Vitamin H deficiency, can cause mucosal and epidermal keratinization, hyperplasia and drying, to produce dry eye disease, severe corneal keratinization thickening, inflammation, or even perforation leading to blindness. Sebaceous glands and sweat glands, skin dryness, occurs when the keratotic follicular papules and hair loss. As a result of the digestive tract, respiratory tract and urinary tract epithelial cells in tissue is not sound, easy to infection.
Enhance immune response and resistance, vitamin H can enhance the body's immune response. And infection resistance, stable normal tissue lysosomal membrane, maintain humoral immunity, cellular immunity and effects a series of cytokine secretion. Large dosage can promote thymic hyperplasia, as immune enhancement agent combination, can enhance immunity. Vitamin H (biotin ) is a maintenance of human natural growth and normal function of the human body must be water soluble vitamin; metabolism of fat and protein are indispensable material, but also maintain the normal growth, development and health of necessary nutrients, prevent hair loss, but also the prevention of modern common juvenile white hair. It also plays an important role for the maintenance of healthy skin, can be used as cosmetics material.
Vitamin H for glycogen gluconeogenesis, the role of fatty acid synthesis and some amino acids, is a key regulatory element, and can help the generation of energy for certain protein synthesis to rise to promote action; at the same time can help cell growth, making fatty acid, metabolism of carbohydrates, fat and protein, and the contribute to the vitamin B group use; also can maintain the hair and skin health need adequate vitamin H ( biotin ); for some men, it can help prevent hair loss; vitamin H ( biotin ) also promote the sweat, neural tissue and bone health, ease muscle pain, the relief of eczema, skin inflammation. Vitamin H ( biotin ) can also help improve the body's immune function. If the body lack of vitamin H, can cause hair loss, depression, skin diseases such as eczema, dermatitis, fat metabolism disorder.

The application of tungsten in various industries
Steel Industry Most of tungsten applied in the production of special steels. The widely used high-speed steel was containing 9-24% of tungsten, 3.8-4.6% of chromium, 1-5% of vanadium, 4-7% of cobalt, 0.7-1.5% of carbon.Magic effects of coconut oil
According to records, coconut oil can be regarded as the nobility of skin care plant extracts. It was rich in exotic tension of tropical plants, which can enhance the contractile force of the pores, perfectly beautify and nourish the skin.Exploring the Potentials of Nano-Aluminum Powder
Nano-aluminum powder, a material with remarkable properties due to its minuscule particle size, is revolutionizing various industries with its high reactivity and large specific surface area. Unlike its bulk counterpart, nano-aluminum powder begins to oxidize at a lower temperature of 550°C, compared to the 950°C oxidation point of ordinary aluminum. This lower ignition energy and full combustion without apparent cohesion make it a superior choice for applications requiring high energy and efficiency. The unique characteristics of nano-aluminum powder, such as faster burning rates and greater heat release, are largely influenced by its synthesis method, which determines its particle size, surface area, and shape.
