Some are wrong but I dont know which ones.

The R group is also called a sidechain The parts shown in the lower image (excepting the variable \'R\' position) are found in all amino acids. The R stands for a single atom of Ruthenium The -COOH is referred to as a \'carboxy\' or \'carboxyl\' group The -NH2 is referred to as an \'amino group\' The carbon attached to the boxed R is called the \'alpha carbon\'

Solution

Ans:

1. True

R group is a side chain which can be a alkyl group or may be a aromatic group.

2. True

All amino acid contain two terminal, one terminal is made up of amino group (-NH₂) and another terminal made up of Carboxylic group (-COOH); and the R group which is attached to the alfa carbon depends on what type amino acid is there.

3. False

Here R stands for the side chain of amino acids. Symbol for Ruthenium is Ru.

4. True

-COOH is referred as a carboxylic group which makes one terminal of amino acid which is called carboxylic terminal.

5. True

-NH₂ is referred as a amino group which makes another terminal of amino acid which is called amino terminal.

6. True

Carbon (which is attached to R group) adjacent to the Carbonyl group is called alfa carbon.
