Fatty acids contain:
Correct answer: C. Carboxylic and alkyl groups
- A. Alcohol and esters
- B. Carboxylic group and isoprenoid
- C. Carboxylic and alkyl groups
- D. Phospholipids and alkyl groups
Explanation
The correct answer is Option C: aromatic and alkyl group. Fatty acids are characterized by a carboxyl group (COOH) at one end and an alkyl chain, which is a long chain of hydrocarbons, on the other. This structure is crucial for the fatty acid's role in biological systems.Option A is incorrect because fatty acids do not contain alcohol and esters within their basic structure. Option B is incorrect, as fatty acids are not made of isoprenoid groups, which are instead building blocks for terpenes and steroids. Option D is incorrect because while phospholipids contain fatty acids, they are not a part of the fatty acid structure itself.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
