- most readily detected - estimated by means of mannose phenylhydrazone (which is insoluble in water) - yiels formation of crystals or precipitate fastest among sugars Manose is the only monosaccharide whose osazone (Phenylhydrazone) is insoluble in water. It is the first sugar that will change its color and form mannose crystals. This property is used to distinguish mannose from other sugars
Monosaccharides are the simplest sugars: - Glucose - Fructose - Galactose - Xylose - Ribose
Glucose, fructose, and galactose make up disaccharides.
Sugars that are monomers are called monosaccharides, which are singe (simple) sugars like glucose, fructose, and galactose. However, lactose is a disaccharide (double sugar) composed of galactose and glucose bonded together.
A music acid is an aldaric acid obtained by nitric acid oxidation of galactose. A music acid test helps distinguish galactose and lactose from other reducing sugars.
Guar gum is a polysacharide (a long chain made of sugars) made of the sugars galactose and mannose. <a>http://sci-toys.com/ingredients/guar_gum.html</a> Galactose is C6G12O6 Mannose is C6H12O6 Guar gum is thus C12H24O12
Lactose and glactose
No. Epimers are sugars that differ in the configuration around one carbon atom. D-Mannose and D-Galactose differ in two carbons (C-2 and C-4). yes. D-glucose and D-mannose are epimers (difference at C-2), D-glucose and D-galactose are epimers (difference at C-4), but D-mannose and D-galactose are not epimer(difference at C-2 and C-4).

Chemically, guar gum is a polysaccharide composed of the sugars galactose and mannose. Guar gum is an extract of the guar bean.The molecular structure reveals that GUAR GUM is a straight chain galactomannan with galactose on every other mannose unit. Beta 1-4 Glycosidic linkages couple the mannose units and the galactose side chains are linked through alpha 1-6. The mannose to galactose ratio has been estimated at 1.8 : 1 to 2: 1.The molecular weight of Guar has reported as 1-2 x 10 6. Further studies indicate that Guar Gum is a rigid rod like polymer because of the beta linkage between the monomer units. Guar hydroxylsare in the CIS position. The CIS position is important since adjacent hydroxyl groups reinforce each other in hydrogen bonding reactions.ThanksBhujabal Yuvraj BabruwanEmail id- yuvi.orgahchem@yahoo.comContact No- +0 99043 52133
