Saturated fatty acid
All Carbon Atoms are
fully attached with or saturated with Hydrogen atoms called saturated fatty acid.Saturated fats have no double bonds in the carbon chain When they combined with glycerol they form solid saturated fat. The longer the chain
of C & H the harder the fat is.
Unsaturated fatty acid
Some Carbon atoms do
not have Hydrogen atoms attached to them that fatty acid is called unsaturated.
It combines with glycerol gives rise to liquid unsaturated fats. The larger the number of unattached Carbon atoms [ poly
unsaturated ] the more liquid and
unsaturated the fat is . There are three types of Unsaturated fatty acids.
- Mono saturated fatty acid
- Poly saturated fatty acid
- Trans fatty acids
Unsaturated fatty acids have at least one bond in the carbon chain. Fats with only one bond in the carbon chains is a monounsaturated fatty acid.
A fatty acid having several double –C=C-C-C-=C- bonds is a polyunsaturated fatty acid.
Trans fats are artificial unsaturated fats formed when
hydrogen gas reacts with vegetable oil to create a solid.
Trans fats not only raise cholesterol levels and interfere
with metabolic processes, but they also deplete good HDL
cholesterol, which helps protect against heart disease.
