Fatty acids are
organic acids having hydrocarbon chains that end in a carboxylic groups (COOH).
Hydrocarbon chains may be straight or having ring structure. Some fatty acids
also possess hydroxyl groups. Length 4-24 carbons. Fatty acids are of two main groups:
saturated and unsaturated. Saturated fatty acids do not posses double bonds in
their carbon chains. They have a general formula CnH2nO2.
Saturated Fats vs Unsaturated Fats
Saturated fats
|
Unsaturated fats
|
They do not possess any double bonds in their fatty
acids.
|
They contain one or more double bonds in their fatty
acids.
|
All certain atoms are fully saturated
|
Carbon atoms are unsaturated in the region of double
bonds.
|
They have straight chains.
|
The chain bends at the double bond.
|
They have higher melting point
|
They have lower melting point
|
Hydrogenation has no effect on saturated fats
|
Hydrogenation converts unsaturated fats into
saturated ones.
|
Saturated fats are solids at room temperature.
|
Unsaturated fats are liquid at room temperature.
|
Animal fats are mostly saturated fats
|
Plant fats are generally unsaturated fats.
|
They increase blood cholesterol
|
Unsaturated fats lower blood cholesterol.
|
Essential fatty acids are absent.
|
Essential fatty acids are present.
|
They are not much affected by exposure to air
|
On exposure to air, they tend to solidify
|
