Ácido alfa lipoico CAS 1077-28-7

Product name: Alpha Lipoic Acid Molecular Formula: C8H14O2S2 Molecular Weight: 206.33 CAS No.: 1077-28-7 Description RS-alpha lipoic acid – also referred to simply as alpha lipoic acid, ALA or thioctic acid – is a fatty acid with powerful antioxidant properties. It is found in meat and fresh green leafy vegetables. RS-alpha lipoic acid is the racemic form of ALA. It is not as bioavailable as R-alpha lipoic acid, the stereoisomer of ALA. R-ALA is more expensive than RS-ALA because it is more bioactive and costs more to produce. Application Alpha Lipoic Acid is a unique anti-free radical substance, commonly known as a broad antioxidant. It is a vitamin-like substance produced in the body. Unlike other antioxidants with special effects produced in the body, Alpha Lipoic Acid is neither strictly fat-soluble nor water-soluble. This makes it possible to promote the activity of other antioxidants in the body and is also a widespread substitute when antioxidants are insufficient. For example, if the content of vitamin C and vitamin E stored in the body is low, Alpha Lipoic Acid can be temporarily supplemented. Because Alpha Lipoic Acid can pass through the blood-brain barrier, it can help reverse the adverse reactions caused by stroke. Alpha Lipoic Acid also helps maintain normal blood sugar levels and prevent serious complications of diabetes. As a coenzyme, Alpha Lipoic Acid plays a role in two key oxidative decarboxylation reactions, namely, in the pyruvate dehydrogenase complex and the α-ketoglutarate dehydrogenase complex, it catalyzes the production and transfer of acyl groups. Alpha Lipoic Acid has antioxidant properties, and has extremely high health care functions and medical value (such as anti-fatty liver and lowering plasma cholesterol). In addition, the sulfhydryl group of lipoic acid is easy to undergo redox reactions, so it can protect the sulfhydryl enzyme from the poison of heavy metal ions. Alpha Lipoic Acid is widely distributed in nature, especially in liver and yeast cells. Alpha lipoic acid often coexists with vitamin B1 in food.
