What makes amino acids unique from fatty acids and sugars?(1 point)

A-Amino acids are building blocks to larger molecules; fatty acids and sugars are not.

B-Amino acids contain nitrogen; fatty acids and sugars do not.

C-Genetic material is made of nucleotides, which contain amino acids; fatty acids and sugars are not part of genetic material.

D-Amino acids make up proteins, which provide energy for the body; fatty acids and sugars do not provide energy.

Many compounds that are of biological importance are comprised of carbon, hydrogen and oxygen and other heteroatoms such as sulfur, nitrogen etc.

The correct answers are as follows;

1) The correct answer is B: carbon, hydrogen, and oxygen

2) The correct answer is A: DNA

3) The correct answer is A: brain

4) The correct answer is D: polysaccharide

5) The correct answer is B: Amino acids contain nitrogen; fatty acids and sugars do not

Biomolecules are molecules that are useful to in biochemical processes.

Several biomolecules are known and are of great importance in the body as they facilitate life.

Most of these biomolecules contain carbon, hydrogen, and oxygen.

A prominent group of biomolecules are the nucleic acids which are composed of nucleotides. They come together to form DNA.

Lipids are another category of biomolecules which are important components of hormones which serve as chemical messengers in the body and regulate the activities of the brain.

Glucose are biomolecules which come together to give larger molecules called polysaccharide.

Both fatty acids and sugars are biomolecules. Fatty acids and sugars all contain carbon, hydrogen and oxygen but not nitrogen. Amino acids are different from fatty acids and sugars because they contain nitrogen.
