Amino acids are mostly synthesized from:
Correct answer: D. A-ketoglutaric acid.
- A. Mineral salts
- B. Fatty acids
- C. Volatile acids
- D. A-ketoglutaric acid.
Explanation
Amino acids are mostly synthesized from a-ketoglutaric acid. These are the precursors of amino acids. A five-carbon compound formed during Krebs' cycle is an a-ketoglutaric acid which is the first dicarboxylic acid formed. Pyruvic acid is converted into alanine, aketoglutaric acid into glutamic acid and OAA into aspartic acid. The polymerization of such amino acids results in the formation of proteins.

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.
