Lipids are a diverse group of organic molecules that play essential roles in living organisms. They are characterized by their hydrophobic nature, meaning they are not soluble in water. The main classes of lipids include triglycerides (fats and oils), phospholipids, steroids, and waxes.
1. **Triglycerides:** These are the most common type of lipids and serve as a major energy storage form in cells. Triglycerides consist of glycerol and three fatty acid chains. Fatty acids can be saturated (no double bonds) or unsaturated (contain double bonds), influencing the physical properties of the lipid.
2. **Phospholipids:** These molecules are crucial components of cell membranes. Similar to triglycerides, they consist of glycerol and fatty acids, but one of the fatty acid chains is replaced by a phosphate group. The hydrophilic (water-attracting) phosphate head and hydrophobic (water-repelling) fatty acid tails contribute to the formation of the lipid bilayer in cell membranes.
3. **Steroids:** Steroids have a unique structure and play various roles in the body, including serving as structural components of cell membranes and acting as signaling molecules. Cholesterol is a common steroid and is a precursor to hormones like estrogen and testosterone.
4. **Waxes:** Waxes are esters of long-chain fatty acids and long-chain alcohols. They often function as protective coatings for plants and animals, helping to reduce water loss and prevent damage.
Lipids serve several vital functions in living organisms:
- **Energy Storage:** Triglycerides store energy in a concentrated form and can be broken down to release energy when needed.
- **Structural Role:** Phospholipids form the basis of cell membranes, providing structure and regulating the passage of substances into and out of cells.
- **Insulation and Protection:** Fats can act as insulators, helping organisms retain heat. Waxes form protective coatings on surfaces.
- **Cell Signaling:** Some lipids, such as certain steroids, serve as signaling molecules that regulate various physiological processes.
In summary, lipids are a diverse group of molecules with varied structures and functions, crucial for the structure, function, and energy balance of living organisms.

2. FATTY ACID NOMENCLATURE
Nomenclature reflects location of double bonds
Also used are common names (e.g: oleic, stearic, palmitic)
Linoleic is also known as 18:2 n-6
This means that F.A is 18 carbons in length, has 2 double bonds, the
first of which is on the 6th carbon
ARACHIDONIC => 20:4 n-6
Alpha Linolenic acid (ALA) and essential n-3 fatty acid, (18:3∆ 9c,
∆ 12c, ∆ 15c)
9. Acetylenic fatty acids
A number of different fatty acids have been identified having triple bonds.
The nomenclature is similar to double bonds , except that the –ane ending of the
parent alkane is replaced with –ynoic acid, diynoic acid, etc.
Lowercase ‘a’ to represent acetylenic bond
Example: tariaric (6-octadecynoic acid)
10. Furan fatty acids
Furan fatty acids are a group of fatty acids that contain a furan ring. To this furan ring, an
unbranched carboxylic acid and, at another position, an alkyl residue are attached. Natural
furan fatty acids are mono- or di-methylated on the furan ring
The first natural acid of this type (with R1 = R2 = H, m = 6 and n = 7) was found in the
seed oil of Exocarpus cupressiformis
Example:
