Description and Uses
Agar is a complex water-soluble polysaccharide composed of gelatin agarose (agarose, also known as agarin) and gelatin free agar pectin (agaropectin, agaric ester) two parts. Agarose is a disaccharide composed of two galactose. Agar can be hydrolyzed by acid to obtain agar disaccharide, agar tetrasaccharide and other oligosaccharides; Oligosaccharides such as neoqiongdisaccharide and neoqiongtetrasaccharide were obtained by enzymatic hydrolysis. Neutral neoqiongdisaccharide with low molecular weight has good hygroscopic and whitening effects.
Neoagarobiose has both a moisturizing effect on skin and a whitening effect on melanoma cells. RagaA11 is an endo-type beta-agarase hydrolysing not only agarose, but also neoagarotetraose, to yield neoagarobiose as the final main product[1].
