Hint: Amino acids are defined as the monomers that can be combined to synthesise polymers and make the proteins, and these amino acids are the building blocks of proteins, and both proteins and amino acids are very necessary, they have an important constituent of biological structures.

Complete answer:
Amino acids are defined as the organic compounds that are made up of the Amine and carboxyl group along with chain R, where it is specific in each amino acid, and the components of the amino acids are carbon, oxygen, hydrogen, and nitrogen. There are many well-known amino acids, and these amino acids are divided in many ways and mainly by the shape and the specific R chain.

Now let us find solution from given options:
Alanine : The pyruvate that is synthesised in glycolysis is transaminated to give rise to alanine. This alanine then travels to the liver where it is again converted to pyruvate. In liver pyruvate is used to form glucose by gluconeogenesis which then goes to the blood and can be utilized by muscles. This pathway is termed as glucose-alanine cycle
Arginine : It is a kind of Semi Essential amino acid that is synthesised very slowly by human beings. It is also known as basic amino acid.
Methionine : Not humans are capable of performing half of the standard amino acid, and these amino acids are non-essential amino acids. One such example is methionine.
Glutamate : The physical properties of amino acids are mainly due to the our group that remains attached to the carbon Atom. On the basis of the R group attached, glutamate is normally an acidic amino acid.

Hence, the correct answer is option (A)

Note: Amino acids are primarily involved in the building blocks for proteins, but specific amino acids are also converted into different types of biologically active compounds. One such example is when tyrosine is converted into the hormone’s thyroxine indent rain and in as well as the skin pigment Melanin.
