Lactose is a disaccharide found in animal milk. It consists of a molecule of D-galactose and a molecule of D-glucose bonded by beta-1-4 glycosidic linkage.. A carbohydrate (/ ˌ k ɑːr b oʊ ˈ h aɪ d r eɪ t /) is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen–oxygen atom ratio of 2:1 (as in water) and thus with the empirical formula C m ...
Carbohydrate conformation refers to the overall three-dimensional structure adopted by a carbohydrate molecule as a result of the through-bond and through-space physical forces it experiences arising from its molecular structure.
Therefore, the molecular structure of a simple monosaccharide can be written as H(CHOH) n (C=O)(CHOH) m H, where n + 1 + m = x; so that its elemental formula is C x H 2x O x. By convention, the carbon atoms are numbered from 1 to x along the backbone, starting from the end that is closest to the C=O group. Monosaccharides are the simplest units ...
Whereas molecular weight (molar mass) for D-glucose monohydrate is 198.17 g/mol, [48] [49] that for anhydrous D-glucose is 180.16 g/mol [50] [51] [52] The density of these two forms of glucose is also different. [specify] In terms of chemical structure, glucose is a monosaccharide, that is, a simple sugar.

They are long-chain polymeric carbohydrates composed of monosaccharide units bound together by glycosidic linkages. This carbohydrate can react with water using amylase enzymes as catalyst, which produces constituent sugars (monosaccharides or oligosaccharides). They range in structure from linear to highly branched.
