Question

Fats and oils are mixture of :
A.Glycerides and saturated fatty acids.
B.Glycerides and unsaturated fatty acids.
C.Glycerides and saturated and unsaturated fatty acids.
D.Only saturated and unsaturated fatty acids.

Answer 1

Hint: Fats are unsaturated hydrocarbons while oils are the unsaturated hydrocarbons . So, they basically are mixtures of these two only .

Complete answer:
Fats and oils are saturated and unsaturated fatty acids. They are basically esters of glycerol with the three fatty acids. These are fats. They are always mixtures of different fatty acids in varying proportions . The degree of saturation depends upon the nature of these acids .
These are basically hydrocarbons . These are commonly known as lipids.
Though both fats and oils appear to be the same at first, they both have some basic differences in them . Let us see what they are.
Fats are solid at room temperature while oils are liquids.
Fats are saturated compounds while oils are unsaturated compounds .
So, we see there is no mention of glycerides in any of fats or oils. A glyceride is not a part of fat or oil.
We come to the conclusion that only saturated and unsaturated fatty acids make up the oils and fats.

Hence, the correct option is C.

Note:
We need to consider the fact that both fats and oils differ from each other in their chemical composition. The consumption of both excess oil and fat is not good for the human body. Also when both of them are kept in open air , they both become oxidised and show rancidity. During rancidity , their higher fatty acids or lipids break down into simpler components.
