Use | Uses arabinose (arabinose) arabinose, also known as pectose, is often combined with other monosaccharides and exists in plant pulp, colloid, hemicellulose, pectic acid, pine cypress tree heartwood, bacterial polysaccharide, and some glycosides in the form of heteropolysaccharides. There are eight isomers of arabinose, such as β-D-arabinose, β-L-arabinose, etc. There are mainly two kinds of arabinose industrial products: D-arabinose can be obtained by degrading D-glucose, which is relatively rare in nature and mainly appears in some bacterial polysaccharides. Natural L-arabinose can be obtained from D-xylose by enzymatic isomerization of uridine diphosphate derivatives, and can also be extracted from arabinose in corn husk hemicellulose. |
