Vanadium oxychloride is also called vanadium oxychloride and vanadium oxychloride. Chemical formula VOCl2, molecular weight 137.85, green, hygroscopic crystal. The relative density is 2.88 13( 13/4℃). Decomposition in water, soluble in dilute nitric acid. Used to make vanadium salts.

Vanadium is in a similar position to essential trace elements such as iron and magnesium in the periodic table of elements, and may have similar biochemical functions.

Heyliger et al. first observed that vanadate can reduce the blood sugar level of diabetic rats, suggesting that vanadate has insulin-like effect. The insulin-like effect of vanadium in vivo is related to insulin receptor and some subsequent links. Vanadate can increase the phosphorus content and tyrosine kinase activity of insulin receptor.

Fantus et al. found that vanadium ion Chemicalbook can activate tyrosine kinase in a dose-dependent manner. Vanadium can keep tyrosine kinase phosphorylated by inhibiting tyrosine dephosphorylation, thus producing insulin-like effect.

Animal experiments have confirmed that the hypoglycemic effect of vanadium ion depends on the existence of endogenous insulin. The effects of vanadium salt on glucose metabolism include: promoting glucose transport into cells; Promote oxidative phosphorylation of glucose; Enhance the sensitivity of tissues to insulin; Promote glycogen synthesis and inhibit gluconeogenesis.

Vanadium salt not only affects sugar metabolism, but also plays an important role in lipid metabolism. Many studies have shown that vanadium can inhibit the synthesis of endogenous cholesterol and accelerate its decomposition. The adverse effects of vanadium deficiency on cardiovascular system are related to the occurrence of diabetic macrovascular complications.
