| Hazard Information | Back Directory | [Description]
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. | [Chemical Properties]
white to off-white fine crystalline powder | [Occurrence]
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. | [Uses]
It can be employed as a sugar in the production of xylitol via biotransformation process. It 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. | [Definition]
ChEBI: D-arabinitol is the D-enantiomer of arabinitol. It is an enantiomer of a L-arabinitol. It is a metabolite found in the aging mouse brain. | [Biotechnological Applications]
D-arabinitol detection
Another approach to the diagnosis of invasive candidosis involves the detection in serum or urine of a metabolite, D-arabinitol, which is produced by most of the medically important Candida species with the exception of C. krusei and perhaps C. glabrata. Various methods have been developed to measure D-arabinitol concentrations in human serum and urine, including enzymatic-fluorometric and enzymatic-colorimetric procedures. Because increased levels of arabinitol are also found in human body fluids when renal function is impaired, the results are reported as the D-arabinitol- creatinine ratio. Although several large studies have demonstrated that patients with candidaemia have ele- vated serum D-arabinitol- creatinine ratios, this approach has still to achieve widespread clinical use. | [storage]
Store at -20°C | [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.
