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 the α- and β- glucose anomers upon its dissolution in the solvent water. This process is usually seen in the chemistry of carbohydrates.
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 rotating the polarized light’s plane in the direction anticlockwise. L isomers are one of the 2 isomers formed by the configurational stereochemistry of the carbohydrates.
is the bottom image the correct enantiomer of the top image?
Enantiomers:
If the stereoisomers have a non-superimposable mirror image of each other, the isomerism known as the enantiomerism. The enantiomers are the same physical and the same chemical properties in an achiral medium. The only difference is that these two compounds rotate the plane-polarized light to the same extent but the angle of the rotation is different.
We can identify if the two compounds are enantiomers or not by noting the RS nomenclature of the compound. The RS nomenclature of these two pairs is given below:
If the RS nomenclature of each chiral carbon is just the opposite of one compound from the other compound then we can say that those pairs will be enantiomers of each other.
