2. Carbohydrates
• Definition – Polyhydroxy aldehydes and
ketones
• Polyhydroxy means they have many hydroxy
(-OH) groups

3. Asymmetric Carbon (or Chiral Carbon)
Website : www.tamsmed.com

4. Aldehyde & Keto
• functional groups
Website : www.tamsmed.com

5. If C=O is present at C1, it is aldehyde group
If C=O is present at C2, it is keto group

6. • Functional carbon is
symmetric, but only in
linear configuration
(In cyclic configuration,
functional carbon becomes
assymetric

7. • Molecular formula = C(H2O)n
• Where n = number of total carbons
Website : www.tamsmed.com

8. • Number of total isomers possible for a
compound is given by the formula
• 2^n
• Where n = number of asymmetric carbons
Website : www.tamsmed.com

9. Molecular formula for carbohydrates C(H2O)n
Where n = Number of Total Carbons
Number of total isomers possible for a
compound is given by the formula =2^n
Where n = Number of Asymmetric Carbons
NOTE : Both formulas contain ‘n’ But this n is
different.
