Question

All amino acids have a central carbon with four components attached to it. One of these components is called the R group. Which of the following best describes the R group?

A.The R group is what stabilizes the amino acid.
B.The R group is the same in all amino acids.
C.The R group gives the amino acid unique characteristics.

Answer 1

C.The R group gives the amino acid unique characteristics.

The R group gives the amino acid its unique characteristics, and allows it to react with other amino acids in unique ways.

Answer 2

Answer:

(C).The R group gives the amino acid unique characteristics.

Explanation:

Amino acids can be defined as compounds, having carbon, nitrogen, oxygen, and hydrogen atoms. Ech amino acid is made up of a carboxylic group, an amino group, a side R chain, and a hydrogen atom.

The R group provides specific characteristics to the amino acids and amino acids are classified into three categories, on the basis of their side chain or R group:

-Amino acids having non-polar R group (such as alanine and valine)

-Amino acids having uncharged, polar R group (such as tyrosine and serine)

-Amino acids having charged, polar r group (such as lysine and glutamate).

Thus, the correct answer is option (C).
