  Kings International Medical Academy is well-known as a premier FMGE coaching centre with a track record of remarkable results. Our exceptional successes in FMGE are undeniable proof of our superiority. We are privileged to have Dr. V.S. Kumar, a highly regarded faculty member, offer an exciting lecture on Biochemistry at Kings International Medical Academy. Let's discuss the topic of "Classification of Fatty Acids" today.

                Classification of Fatty Acids

Aliphatic Carboxylic Acids

Depending upon chain length:
C₂-C₆ - Short chain fatty acid
C₈-C₁₄ - Medium chain fatty acid
≥C₁₆ - Long chain fatty acid

Based upon double bond:
Saturated FA: No double bond
Unsaturated FA: Present (double bond)
MUFA = one “=”
PUFA= ˃ one “=”

Butter Butyric Acid (4C), Valeric Acid (5C),
Caproic Acid (6C)- (also in coconut milk)
Vinegar Acetic Acid (2C)


Linolenic acid
x-Linolenic Acid

arachidonic – Semi essential FA

Linoleic → AA
Functions:   ↓Risk of CAD
       ↓ Risk of Fatty Liver
- of EFA → Fatty liver, ↓ in Fibronolytic activity, Acanthosis of skin, ↓ in oxi. Phosphorylation
Saponification number: Hydrolysis of TAG into glycerol & soap → by Alkali
The mg of KOH req. to Saphonify 1gm of fat/oil completely
Inversely proportion to the length of chain of FA in the fat
Human fat: 195-200
Butter: 230-240
Coconut oil: 250-260

Sphingo lipidosis/ Lysomal storage disorder:

Ds’ Enzyme
Fabry’s x-galactosidase
Krabbe’s ß- galactosidase
Gaucher’s ß-glucisidase
Tay sach’s Hexaminadase A
Sand hoff’s Hexaminadase A & B
Niemann pick Sphingomyclinase
Farbers Ceramidase
Metachromatic Levkodystrophy Aryl sulphatase

Oral drug: Miglustat

Lipo proteins

1. TG – Chylomicrons, VLDL
2. Chol- LDL, HDL
Apo- Proteins:
APO-A → A₁ A₁₁ Aᵥ
APO-B → B₄₈ B₁₀₀
Synthesis of TAG – Liver & Adippose tissue
