Question

Which atoms give the amino acid its unique chemical and physical properties? the CH3 group the amino groups the oxygen atom the hydrogen atom

Answer 1

Answer:

the amino groups

Explanation:

Amino acids are monomers of proteins. They have two functional groups and are said to be bifunctional. These functional groups are:

>>>>>amino group (-NH₂)

>>>>>carboxyl group (-COOH)

Amino acids have a dipolar ion structure or zwitterion. It shows this structure in aqeous solutions.

It is the functional groups that accounts for the physical and chemical properties of amino acids.

Amino acids have the following physical properties:

>They have a crystalline nature

>Have high solubility with a high melting point

Amino acids are amphoteric in nature and it they react with both an acid and base.

These amino acids combines to form giant protein molecules.
