Arabinose-Gold Monte Health

넳 넲

L- arabinose, also known as gum aldose, is a valeraldehyde glucose.In nature, l-arabinose rarely exists in the form of monosaccharide, but it is usually combined with other monosaccharides and exists in the form of heterosaccharide in gel, hemi-fibrin, pectinic acid, bacterial polysaccharide and some glycosides. It is highly stable to heat and acid.
