Responses
Amino acids contain oxygen.
Amino acids contain oxygen.
Amino acids contain hydrogen.
Amino acids contain hydrogen.
Amino acids contain carbon.
Amino acids contain carbon.
Amino acids contain nitrogen.
Amino acids contain nitrogen.
Amino acids contain nitrogen, which is not a component of starch.
The correct answer is "Amino acids contain nitrogen."
To understand why amino acids contain nitrogen while starch does not, let's break down the structures of these two compounds.
Amino acids are the building blocks of proteins. They consist of an amino group (NH2), a carboxyl group (COOH), a hydrogen atom (H), and an R group (which varies among different amino acids). The amino group in amino acids contains nitrogen.
On the other hand, starch is a complex carbohydrate made up of glucose molecules. These glucose molecules are composed of carbon, hydrogen, and oxygen atoms. Starch does not contain nitrogen.
To find the correct answer, you could have approached the question by knowing the basic composition of amino acids and the fact that nitrogen is a characteristic element present in amino acids but not in starch.
