Answer :
In this case, the molecule that contains an amino group and a carboxyl group is known as an amino acid.
Amino acids are the building blocks of proteins and play crucial roles in various biological processes in living organisms. They consist of an amino group (-NH2) and a carboxyl group (-COOH) attached to a central carbon atom, known as the alpha carbon. Additionally, there is a side chain (R group) attached to the alpha carbon that differentiates one amino acid from another.
Here's a simple breakdown:
1. Amino group (-NH2): This group consists of a nitrogen atom bonded to two hydrogen atoms and is present in all amino acids.
2. Carboxyl group (-COOH): This group consists of a carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl group (OH) and is also present in all amino acids.
3. Side chain (R group): The side chain varies among different amino acids and determines their unique properties.
Therefore, the correct answer to the question is "amino acid" since it specifically refers to molecules containing both an amino group and a carboxyl group.
