Question

____ describes the type of molecule characterized by a characteristic functional group along with a carboxylic acid and amino functional group.
lipids
amino acids
carbohydrates
hydrocarbons

Explanation:

Amino acids are molecules that have both a carboxyl group (carboxylic acid functional group) and an amino group (amino functional group) along with a side chain. Lipids are a diverse group of hydrophobic molecules, carbohydrates are composed of sugar units, and hydrocarbons consist of only carbon and hydrogen. So the molecule with a carboxylic acid and amino functional group is an amino acid.

Answer:

Amino Acids (the option corresponding to "Amino Acids" among the given choices)
