D-arabinitol C화학적 특성, 용도, 생산
개요
D-arabinitol is a characteristic metabolic product of candida species. While candida ssp. produces exclusively D-arabinitol, L-arabinitol is developed by the body’s own metabolism. D-arabinitol serum levels increase if candida yeasts proliferate within the organism and cause invasive Candidiasis. Both D-arabinitol and L-arabinitol are present in normal urine, and can easily be measured by gas chromatography of urine samples collected on filter paper.화학적 성질
white to off-white fine crystalline powder출처
D-Arabinitol (lyxitol) is found in lichens; in a variety of fungi; in the urediospores of wheat stem rust; in the dried herbiage of the Peruvian shrub, pichi, along with D-mannitol, dulcitol, and perseitol; and in the avocado. It is formed by fermentation of glucose and in 40% yields using blackstrap molasses. D-Arabinitol is formed by catalytic hydrogenation of D-arabinose in the presence of Raney nickel and from the γ-lactones of D-arabinonic and D-lyxonic acids by reduction with sodium borohydride.용도
D-Arabitol, a rare sugar alcohol, is a substrate used to identify, differentiate and characterize enzyme such as the gluconobacter oxydans dehydrogenase(s), Gox2181, hyperthermophilic D-arabitol dehydrogenase from Thermotoga maritime and NAD-dependent D-arabitoldehydrogenase from acetic acid bacterium, Acetobacter suboxydans.Purification Methods
This pentol, which occurs in lichens and fungi, is purified by recrystallisation from 90% EtOH or MeOH. [Ashina & Yamagita Chem Ber 67 801 1934, derivarives: Nakagawa et al.
