A broad group of naturally occurring molecules that are generally soluble in
organic solvents but sparingly
soluble in water.Long chain-hydrocarbons that are constituent elements of fats.
Another classification of lipids. Fats are a type of triglycerides,
though they are made up of fatty acids and glycerides.

Saturated Unsaturated•Saturated fatty acids form saturated fats
•Unsaturated fatty acids form unsaturated fats (duh!)
•Animal fats are generally saturated fats
•Plant fats are generally unsaturated fats
Saturated UnsaturatedSaturated fats remain solid at room temperature as their melting points are relatively high.
Unsaturated fats are liquid at room temperature as their melting points are low.
1. Simple Lipid
Saturated with hydrogen atoms, i.e.- carbon atoms are bound to as many hydrogen atoms as possible. Each carbon atom is generally joined by single bonds.
Not necessarily bound to as many hydrogen atoms as possible. They may be bound by a covalent bond instead(double, triple bond etc)s
2. Phospholipid
•Polar head is hydrophyllic, i.e.- it is attracted (phil) to water (hydra)
•Non-polar tail is hydrophobic, i.e.- its is repulsed (phobe) by water (hydra)
•Polar head faces and interacts with water
•Non-polar tails stay away from water
This structure makes lipids sparingly soluble
•Polar head appears as round in shape
•Non-polar tail appears as…umm…tails
