Which essential fatty acid is rarely found to be deficient as it is typically consumed in abundance in the majority of diets?
a. alpha-linoleic acidb. linoleic acidc. eicosapentaenoic acidd. docosahexanoic acid

B. Linoleic acid

Explanation:

Linoleic acid was discovered by chance in 1978 by Michael W. Pariza at the University of Wisconsin looking for mutagene formations in meat during cooking. It is called a conjugated linoleic acid (CLA) to a family of several isomers of linoleic acid (at least 13 are known), which are very common in vegetable oils (corn oil, soybean oil, sunflower oil, etc. ) and in animal fat.

The conjugated linoleic acid is formed by several types of fatty acids, all of them different in their chemical structure. CLAs are a “trans” fat that is not harmful to health, but instead is beneficial

Natural Sources of Conjugated Linoleic Acid

The main natural sources of conjugated linoleic acid in food are:

Beef

Butter

cheese

Lamb

Homogenized milk

Yogurt

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
