Question

ASSERTION: amino acids are called alpha-amino acids.
REASON: amino acids are organic compounds containing an amino group and an acidic group as substitutes on the alpha-carbon.
A. Both Assertion and Reason are correct and Reason is the correct explanation for assertion.
B. Both assertion and reason are correct but reason is not the correct explanation for assertion.
C. Assertion is correct but reason is incorrect
D. Both assertion and reason are incorrect.

Answer 1

Hint: Amino acid are organic compounds containing an amino group and an acidic group as substitutes on the alpha carbon. Retention times, accurate masses for TBDMS-derivatized amino acids are already summarized. It contains a carboxylic moiety along with it.

Complete answer:
Amino acids are organic molecules that act as the basic structure for the creation of proteins and they are called the building blocks of life.
Alpha-amino acid is a simple molecule that is made of a central carbon atom that is bound to a primary amine group NH2 and to a carboxylic group COOH.
Since they contain the amino group and an acidic group they are called alpha-amino acid.

Therefore, the answer to the above question is option (A) both assertion and reason are correct and reason is the correct explanation for assertion.

Note:
The key elements of an amino acid are hydrogen, oxygen and nitrogen although many other elements are present in the side chains.
Almost 500 naturally occurring amino acids are known to mankind of which 20 of them appear in the genetic code.
In proteins amino acid residues form the largest component of human muscles and other different types of tissues.
Amino acid participates in processes such as neurotransmitter transport, biosynthesis.
There are 9 amino acids that are essential for humans which are proteinogenic as they can’t be produced from other compounds except the human body.
Essential amino acids differ among different species.
Amino acids are important in nutrition and commonly used in nutritional supplements, food due to their biological significance.
The production of drugs, biodegradable plastics and chiral catalysts are included in industrial use.
