Verified
A −COOH group is characteristic of ____ and functions to ____.
A) amino acids and fatty acids; make the molecule acidic
B) proteins and coenzymes; increase the rigidity of the molecule
C) proteins and nucleotide bases; make the molecule more basic
D) monosaccharides; increase solubility in water
E) DNA; turn genes "off"
−COOH Group
A functional group characteristic of carboxylic acids, consisting of a carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl group.
Amino Acids
Organic compounds that combine to form proteins and are used by the body for various functions including tissue repair and the synthesis of neurotransmitters.
Fatty Acids
Organic compounds made of long hydrocarbon chains ending in a carboxylic acid group, essential in diet and biology for energy storage and cell membrane structure.

Final Answer :
A
Explanation :
The −COOH group, also known as a carboxyl group, is found in both amino acids and fatty acids. It functions to make the molecule acidic by donating a hydrogen ion (H+) in solution. This group is important for the formation of peptide bonds between amino acids in proteins and for the acid-base balance in the body.
