Question

Which three components are common to all amino acids? an amino group, a carboxyl group, and an R group an amino group, a phosphate group, and an R group a five-carbon sugar, a phosphate group, and a nitrogenous base a five-carbon sugar, an amino group, and a nitrogenous base

Answer 1

in every amino group, a caboxylic, amino and hydrogen is common.

Answer 2

Amino acids are the building blocks of a bio-molecular structure called protein. The structure of amino acid is comprised of three components:

- An amino group  

- A carboxyl group  

- R group  

The difference in every amino acid is because of the difference of R group whereas the carboxylic and amino group remains constant.
