Microtubules are a component of the cytoskeleton, found throughout the cytoplasm. These tubular polymers of tubulin can grow as long as 50 micrometres, with an average length of 25 µm, and are highly dynamic. The outer diameter of a microtubule is about 24 nm while the inner diameter is about 12 nm. Microtubules are found in eukaryotic cells and are formed by the polymerization of a dimer of two globular proteins, alpha and beta tubulin. Tubulin is one of several members of a small family of globular proteins. The tubulin superfamily includes five distinct families, the alpha-, beta-, gamma-, delta-, and epsilon-tubulins and a sixth family which is present only in kinetoplastid protozoa. The most common members of the tubulin family are α-tubulin and β-tubulin, the proteins that make up microtubules. Microtubules are very important in a number of cellular processes. They are involved in maintaining the structure of the cell.

    D-chiro-Inositol
    		Inhibitor 98.0%
    D-chiro-Inositol is a stereoisomer of inositol that exhibits activities such as improving glucose metabolism, anti-tumor effects, anti-inflammatory properties, and antioxidant activity. D-chiro-Inositol effectively alleviates cholestasis by enhancing bile acid secretion and reducing oxidative stress. D-chiro-Inositol improves insulin resistance, lowers hyperglycemia and circulating insulin levels, reduces serum androgen levels, and ameliorates some metabolic abnormalities associated with X syndrome by mimicking the action of insulin. Additionally, D-chiro-Inositol can induce a reduction in pro-inflammatory factors (such as Nf-κB) and cytokines (such as TNF-α), thereby exerting anti-inflammatory effects. D-chiro-Inositol may be used in the study of liver cirrhosis, breast cancer, type 2 diabetes, and polycystic ovary syndrome.
