Galactitol

Galactitol, Pharmaceutical Secondary Standard; Certified Reference Material

C6H14O6 (182.079)


Galactitol or dulcitol is a sugar alcohol that is a metabolic breakdown product of galactose. Galactose is derived from lactose in food (such as dairy products). When lactose is broken down by the enzyme lactase it produces glucose and galactose. Galactitol has a slightly sweet taste. It is produced from galactose in a reaction catalyzed by aldose reductase. When present in sufficiently high levels, galactitol can act as a metabotoxin, a neurotoxin, and a hepatotoxin. A neurotoxin is a compound that disrupts or attacks neural cells and neural tissue. A hepatotoxin as a compound that disrupts or attacks liver tissue or liver cells. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of galactitol are associated with at least two inborn errors of metabolism, including galactosemia and galactosemia type II. Galactosemia is a rare genetic metabolic disorder that affects an individuals ability to metabolize the sugar galactose properly. Excess lactose consumption in individuals with galactose intolerance or galactosemia activates aldose reductase to produce galactitol, thus depleting NADPH and leading to lowered glutathione reductase activity. As a result, hydrogen peroxide or other free radicals accumulate causing serious oxidative damage to various cells and tissues. In individuals with galactosemia, the enzymes needed for the further metabolism of galactose (galactose-1-phosphate uridyltransferase) are severely diminished or missing entirely, leading to toxic levels of galactose 1-phosphate, galactitol, and galactonate. High levels of galactitol in infants are specifically associated with hepatomegaly (an enlarged liver), cirrhosis, renal failure, cataracts, vomiting, seizure, hypoglycemia, lethargy, brain damage, and ovarian failure. Galactitol is an optically inactive hexitol having meso-configuration. It has a role as a metabolite, a human metabolite, an Escherichia coli metabolite and a mouse metabolite. Galactitol is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Galactitol is a natural product found in Elaeodendron croceum, Salacia chinensis, and other organisms with data available. Galactitol is a naturally occurring product of plants obtained following reduction of galactose. It appears as a white crystalline powder with a slight sweet taste. It may form in excess in the lens of the eye in galactosemias a deficiency of galactokinase. A naturally occurring product of plants obtained following reduction of GALACTOSE.

C30H50O (426.3861)


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].
