Question

A saturated fatty acid is
a) Arachidonic acid
b) Stearic acid
c) Oleic acid
d) Linoleic acid

Answer 1

Saturated fats contain only single bonds between carbon molecules and are saturated with hydrogen molecules. Unsaturated fats, on the other hand, contain at least one double bond between carbon molecules.

Complete answer:
Saturated fats are solid at room temperature due to the saturation of hydrogen ions, whereas unsaturated fats, such as olive oil, are liquid at room temperature. Animal products such as milk, cheese, and meat, as well as tropical oils such as coconut and palm oil, contain saturated fats.
Even though research on the health effects of saturated fat consumption is far from definitive, saturated fats are often classified as "poor" fats and are often grouped with trans fats — a form of fat known to trigger health issues.
Stearic acid has an 18-carbon chain and is a saturated fatty acid. The IUPAC name for octadecanoic acid is octadecanoic acid. It's a waxy substance. Stearates are the salts and esters of stearic acid. Following palmitic acid, stearic acid is one of the most popular saturated fatty acids found in nature as its ester. Stearin is a triglyceride made up of three molecules of stearic acid.
Arachidonic acid is an omega-6 polyunsaturated fatty acid. Its structure is similar to that of cupuaçu butter's saturated arachidic acid. Linoleic acid is a polyunsaturated essential fatty acid that is primarily found in plant oils. Prostaglandins and cell membranes are biosynthesised by it. Linoleic acid is a colourless to straw-colored liquid, according to the NCI Thesaurus. A polyunsaturated acid essential for human diet.

The correct answer is option (B) Stearic acid.

Note:
Stearic acid is mostly used to make detergents, soaps, and cosmetics such as shampoos and shaving creams. Soaps are produced indirectly from triglycerides containing stearic acid esters, rather than directly from stearic acid. Some foods contain stearic acid (E number E570).
