Question

Assertion: Arachidic acid is an unsaturated fatty acid.
Reason: There are one or more double bonds present between carbon atoms and unsaturated fatty acids.
A. Both assertion and reason are correct and reason is a correction explanation for assertion.
B. Both assertion and reason are correct but reason is not the correct explanation for assertion.
C. Assertion is correct but reason is incorrect.
D. Both assertion and reason are incorrect.

Answer 1

Hint: Arachidic acid is the chemical messenger that is released by the muscle during weight training. It controls the physiological response to the exercise. The fatty acid is a carboxylic acid with a long aliphatic chain that is either saturated or unsaturated.

Complete answer:
When there is some irritation or injury there will be a release of arachidic acid. This will be oxygenated by oxygenated enzymes that will result in the formation of inflammatory mediators, eicosanoids. The main function of eicosanoids includes mounting or inhibition of inflammation, regulation of abortion, and normal childbirth.
Arachidic acid is a saturated long chain of fatty acid made up of 20 carbon atoms. Naturally, it is found in peanut oil. Arachidic acid is used in the production of detergents, used as lubricants. The reduction of arachidic acid will give arachidonic alcohol.
Unsaturated fatty acids are those which have the presence of one or more double bonds in the fatty acid chain.
According to the assertion, arachidic acid is an unsaturated fatty acid. But arachidic acid is a saturated fatty acid.
The correct answer is option D i.e. both assertion and reason are incorrect.

Note:
Unsaturated fatty acids have the capacity to hold more hydrogen atoms. There are two types of unsaturated fatty acids- monounsaturated fats that have the presence of a single double bond. Polyunsaturated fatty acids have the presence of two or more double bonds.
