Inositol is a white fine crystal or crystalline powder.Inositol is odorless and sweet.Melting point of 224-227 ℃.Relative density of inositol was 1.752, 1.542(dihydrate).Inositol is stable in air and stable to heat, strong acids and bases.Inositol solution was neutral to litmus.No optical rotation.The main use in medicine for the preparation of a variety of vitamin pills and a variety of nutritional amino acids-vitamin infusion products.In addition, in medicine can also be used for the treatment of cirrhosis, hepatitis, fatty liver, vascular sclerosis, high blood cholesterol, diabetes, tetrachloride poisoning and other diseases as well as for the synthesis of nicotinic acid inositol ester, maitong and other drugs;At the same time, it can also be directly used as medicine, such as inositol tablets, liver alcohol, shugan tablets.Inositol can also prevent skin aging and hair loss, promote the growth of various bacteria and yeast, as a food additive.Inositol is also a good feed additive. The addition of a certain amount of inositol in the feed of prawns and salmon can not only improve the growth rate, but also avoid the most common deficiency of inositol in fish.Also called meso-ino-sitol (meso-ino-sitol).It was first found in muscles and has since been widely found in microorganisms and animals.Almost all living things contain inositol in its free or bound state.The form of hexaphosphoinositol in the nucleated red blood cells of plants and birds is in the form of hexaphosphate.In addition, free inositol, a component of phosphatidylinositol, is mainly found in muscles, heart, lungs and liver.Myoinositol is an essential nutrient source for birds and mammals. The lack of myositol, for example, can cause hair loss in mice and abnormal peripheral eye symptoms in rats.Large amount of inositol could be metabolized in rats, but the amount of excretion in urine was not much.Sharks seem to be able to turn inositol into a store of energy.
