Carbohydrates Classification Interactive Activity

Definition: Carbohydrates are bio molecules which are polyhydroxy aldehydes or ketones made  up of Carbon C, Hydrogen H and Oxygen O in the ratio (1:2:1)

Before attempting this activity, if you want to refresh your memory..Then visit the following posts

• Notes on Carbohydrates  
• Classification of Carbohydrates

Based on functional group. carbohydrates are classified into

• Aldoses: Carbohydrates with aldehyde(-CHO) functional group Eg: Glucose
• Ketoses: Carbohydrates with ketone (=C=O) functional group Eg: Fructose

Based on Rotation (Dextro and Levo)

• Based on stereochemistry of the highest numbered chiral carbon of the Fischer projection.
• If the hydroxyl group of the highest numbered chiral carbon is pointing to the right, the sugar is designated as D (Dextro: Latin for on the right side). 
• If the hydroxyl group is pointing to the left, the sugar is  Levo (Levo: Latin for on the left)
• Most naturally occurring carbohydrates are of the D-configuration.
