C30H50O (426.386145)


Beta-amryin, also known as B-amryin, is a member of the class of compounds known as triterpenoids. Triterpenoids are terpene molecules containing six isoprene units. Beta-amryin is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Beta-amryin can be found in pigeon pea, which makes beta-amryin a potential biomarker for the consumption of this food product.

Beta-amyrin, also known as amyrin or (3beta)-olean-12-en-3-ol, is a member of the class of compounds known as triterpenoids. Triterpenoids are terpene molecules containing six isoprene units. Thus, beta-amyrin is considered to be an isoprenoid lipid molecule. Beta-amyrin is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Beta-amyrin can be synthesized from oleanane. Beta-amyrin is also a parent compound for other transformation products, including but not limited to, erythrodiol, glycyrrhetaldehyde, and 24-hydroxy-beta-amyrin. Beta-amyrin can be found in a number of food items such as thistle, pepper (c. baccatum), wakame, and endive, which makes beta-amyrin a potential biomarker for the consumption of these food products. The amyrins are three closely related natural chemical compounds of the triterpene class. They are designated α-amyrin (ursane skeleton), β-amyrin (oleanane skeleton) and δ-amyrin. Each is a pentacyclic triterpenol with the chemical formula C30H50O. They are widely distributed in nature and have been isolated from a variety of plant sources such as epicuticular wax. In plant biosynthesis, α-amyrin is the precursor of ursolic acid and β-amyrin is the precursor of oleanolic acid. All three amyrins occur in the surface wax of tomato fruit. α-Amyrin is found in dandelion coffee . β-Amyrin, an ingredient of Celastrus hindsii, blocks amyloid β (Aβ)-induced long-term potentiation (LTP) impairment. β-amyrin is a promising candidate of treatment for AD[1]. β-Amyrin, an ingredient of Celastrus hindsii, blocks amyloid β (Aβ)-induced long-term potentiation (LTP) impairment. β-amyrin is a promising candidate of treatment for AD[1].
