Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Carboxylic acid and amine
Concept:

The very name "amino acid" directly reveals its biochemical architecture.

Solution:

  • Every standard amino acid contains a central alpha-carbon.


  • Attached to this carbon are two primary functional groups:


  • 1. A basic amine group (\( -\text{NH}_2 \)).


  • 2. An acidic carboxylic acid group (\( -\text{COOH} \)).


  • (They also contain a hydrogen atom and a variable 'R' side chain).


Why other options are incorrect:

Ethers and aldehydes are not foundational backbone components of amino acids.
