MCQ
The functional group which is found in amino acid is
- A$ - COOH$ group
- B$ - N{H_2}$ group
- C$ - C{H_3}$ group
- ✓Both $(a)$ and $(b)$
✓
Answer
Correct option: D.
Both $(a)$ and $(b)$
d
$COOH$ and $NH _3$ (amine group). So every amino acid has a central carbon with a $H, R$ group (varies for each amino acid), a carboxylic group and an amine group. These groups are joined to a single (aliphatic) carbon. The carbon directly attached to a carboxyl group is the alpha position, so the amino acids in proteins are all alpha-amino acids.
