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.
Show a chiral carbon, optically active, and meso giving rise to diastereomers.
Interpretation-
To show a compound which have a chiral carbon , optically active and which give a meso giving diastereomers .
Introduction-
- Chiral carbon- A chiral carbon is a carbon center which have four different type of atoms or groups at that carbon center .
- Optically active compound - Compound which have optical rotation and do not shows plane of symmetry , center of symmetry and axis of symmetry called optically active compound . Generally chiral center having compound called optical active compound but it's not a mandatory condition.
- Meso compound- Meso compound is a non-optically active member of a set of stereoisomers, at least two of which are optically active.
- Diastereomers- Compound which have non - identical or non mirror image stereoisomers.
