Which Compound contains nitrogen?

Amino Acids

Glucose

Water

Starch

Amino Acids

Amino acids contain nitrogen.

To determine which compound contains nitrogen, we need to examine each option and check for the presence of nitrogen:

1. Amino Acids: Amino acids are the building blocks of proteins. They contain both carbon, hydrogen, oxygen, and nitrogen, making them a compound that contains nitrogen.

2. Glucose: Glucose is a simple sugar and consists of carbon, hydrogen, and oxygen atoms only. It does not contain nitrogen.

3. Water: Water, or H2O, is a compound composed of hydrogen and oxygen atoms. It does not contain nitrogen.

4. Starch: Starch is a complex carbohydrate and consists of long chains of glucose molecules. Similar to glucose, starch does not contain nitrogen.

So, the compound that contains nitrogen from the given options is amino acids.
