SSC MTS EXAM

Detailed explanation-1: -The fatty acids are lipids that contain long-chain hydrocarbons terminated with a carboxylic acid functional group. Because the long hydrocarbon chain, fatty acids are hydrophobic (“water fearing”) or nonpolar.

Detailed explanation-2: -Steroids are another class of lipid molecules, identifiable by their structure of four fused rings. Although they do not resemble the other lipids structurally, steroids are included in lipid category because they are also hydrophobic and insoluble in water.

Detailed explanation-3: -(c) The lipids are the non-polar biomolecules because they are constructed of non-polar chains of carbon and hydrogen.
