a.Polymerisation of 2 carbon compounds
b.Decomposition of fats
c.Polymerisation of glycogen
d.Conversion of glycogen

Answer 1

A fatty acid is a carboxylic acid with a long aliphatic chain that is either saturated or unsaturated in chemistry, particularly biochemistry. Fatty acids are significant nutritional sources of fuel for animals as well as structural components of cells in any of these forms. Fatty acids are a key component of lipids in some species, such as microalgae, but they are not found in their freestanding form in other creatures. Instead, they are present as three types of esters: triglycerides, phospholipids, and cholesteryl esters.

Complete answer:
Glycerol and fatty acids are the two major components of a fat molecule. Glycerol is a three-carbon alcohol containing five hydrogens and three hydroxyl (OH) groups. Fatty acids are made up of a long chain of hydrocarbons with a carboxyl group attached. They can contain anywhere from 4 to 36 carbons, but the majority have 12 to 18. Fatty acids are linked to each of the three carbons of the glycerol molecule through an ester bond through the oxygen atom in a fat molecule. Three molecules are released during the ester bond formation. Triacylglycerols or triglycerides are lipids that are made up of three fatty acids and a glycerol.
Polymerization of two carbon compounds produces long chain fatty acid molecules. A fatty acid is a carboxylic acid having a lengthy, saturated or unsaturated aliphatic tail (chain). The majority of naturally occurring fatty acids contain an even number of carbon atoms in their chain, ranging from 4 to 28. Unsaturated fatty acids are those with double or triple carbon-carbon bonds. Saturated fatty acids are those that have no double bonds. They also differ in length. Fatty acids having aliphatic tails of 13 to 21 carbons are known as long-chain fatty acids (LCFA).

Hence option a Polymerisation of 2 carbon compounds is correct.

Note:
Saturated and unsaturated fatty acids exist. A fatty acid chain is considered to be saturated if there are only single bonds between nearby carbons in the hydrocarbon chain. Because single bonds increase the quantity of hydrogens on each carbon, saturated fatty acids are hydrogen-rich. Saturated fats include stearic acid and palmitic acid, which are often present in meat.
