                                                                                        LIPIDS

• Heterogeneous group of compounds
• Not soluble in H₂O but are soluble in non-polar organic solvents like ether, chloroform, etc.

Classification:

(Bloor’s classification)

1. Simple lipids
2. Complex lipids
3. Derived lipids
4. Miscellaneous lipids

Simple lipids

Esters of FA + glycerol

• Fats 4 oils (FA + glycerol)
• Waxes- FA + Alc. (other than glycerol)

Example: Bee wax, Lanolin

Complex lipids

FA + AIC (glycerol/sphingosine)

+ Additional group (NB + Po4⁻)

• Phospholipids
• Glycolipids
• Amino lipids, Sulpho lipids, Lipo proteins

Phospholipids

FA + AIC (G/s) + Po4⁻ + NB

Glycero- PL (Simplest, Phosphatidic acid)

Sphingo- PL

PA → G-PL

• Nitro- B⁺
• Nitro- B⁻

Nitro- B⁺

1. Lecithin
2. Cephalin
3. Phosphatidyl Serine

Nitro- B⁻

1. P.inositol
2. P.glycerol
3. Di-P glycerol/ Cardiolipin

Sphingo-PL – (FA + S + Po4⁻ + NB)

Glycolipids

Neutral- Cerebrosides- Ceramide + mono

             -Globosides- Ceramide + oligo

Acidic- gangliosides- Ceramide + oligo + NANA (cialic)
