About the precipitation method of sugar
First, that color may be pigment, not necessarily monosaccharide, can increase hydrogen peroxide.Second, my precipitate is ethanol, did not try methanol.Third, if you think of single sugar, use your sample to add DNS color to see how the color is.

1. This monosaccharide is soluble in methanol and ethanol, which is more than ethanol according to a similar phase-dissolving principle, so the solubility should be greater in methanol; 2, with the sugar chainExtension, its solubility should be gradually narrowed, but still to see polarity matching; 3, even if it can be soluble in water, it may be some impurities of water soluble, I think it is impossible to be a pure sugar groupDivision, this is afraid that you can't reach; 4, the fourth question is not very knowing, I will also want to smell, I hope everyone will guide.

1. Because the solubility of monosaccharides in water is large, it means that its polarity is relatively strong, the polarity of methanol is larger than the polarity of ethanol, so they should be relatively large in methanol; 2, dicarries and three ponds belong to oligosaccharides, so the effect should be single sugar; 3, I think even if it is a sugar component, it is impossible to reach pure sugar, and the existence of impurities is inevitable. Unless you passMany times separation purification may be achieved, but hundreds of percent is certain; 4, I don't know this.
