The chemical and physical properties of amino acids are based on:
Correct answer: C. R-group
- A. - NH2 group
- B. -COOH group
- C. R-group
- D. All of the above
Explanation
The properties of amino acids are determined by their R-groups, also known as side chains. These groups vary among different amino acids and can impart different characteristics, such as hydrophobicity, charge, and size, which influence the amino acids' behaviour and role in proteins. The -NH₂ and -COOH groups are constant among all amino acids and do not contribute to these variations. Therefore, the correct answer is the R-group.

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.
