Which of the following amino acid is next to glycine with respect to the molecular structure?
Correct answer: A. Alanine
- A. Alanine
- B. Serine
- C. Ethanolamine
- D. Aspartic acid
Explanation
Glycine is the simplest amino acid, having a hydrogen atom as its side chain. Alanine is the next amino acid in terms of molecular structure after glycine. Alanine has a methyl group (-CH3) as its side chain, which adds a single carbon and three hydrogen atoms to the structure compared to glycine.

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.
