Explanation The D-glucose molecule contains six carbons and among these six carbons, four carbons are chiral centres. The carbons-2, 3, 4, 5 are chiral carbons as they are bonded to four different groups. The carbons-1 and 6 are non-chiral centres. In D-glucose, the C-2 contains four different groups such as –CHO , –OH , -H and the C-3

Carbohydrates

Carbohydrates are the organic compounds that are obtained in foods and living matters in the shape of sugars, cellulose, and starch. The general formula of carbohydrates is Cn(H2O)2. The ratio of H and O present in carbohydrates is identical to water.

Starch

Starch is a polysaccharide carbohydrate that belongs to the category of polysaccharide carbohydrates.

Mutarotation

The rotation of a particular structure of the chiral compound because of the epimerization is called mutarotation. It is the repercussion of the ring chain tautomerism. In terms of glucose, this can be defined as the modification in the equilibrium of th…

L Sugar

A chemical compound that is represented with a molecular formula C6H12O6 is called L-(-) sugar. At the carbon’s 5th position, the hydroxyl group is placed to the compound’s left and therefore the sugar is represented as L(-)-sugar. It is capable of rotat…
