3. Structure And Chemistry
• Elucidated by Paul Karrer (N.P-1937).
• Derivatives of chromane (tocol) ring with
isoprenoid side chain.
• About 08 tocopherols have been identified.
• Named as – α,β,γ,δ
(On the basis of the number & position of the methyl group on the
chromane ring)
7. Dietary vitamin E is absorbed
in the duodenum along with lipids.
It is transported to the liver
through chylomicron.
Stored in Liver and adipose tissue

• Depress leucocyte oxidative bactericidal activity.
OTHER FUNCTIONS OF VITAMIN E
12. • Stabilize reactions or situations that typically
produce free radicals
• Required for Proper Hair Growth (Beauty Vitamin
along with BIOTIN)
• Preserves & maintains germinal epithelium of
gonads.
