A

`alpha`-amino acid

B

basic amino acid

C

amino acid synthesised in body

D

`beta`-amino acid

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
Lysine whose structural formula is written below as
`H_(2)N-(CH_(2))_(4)-underset(" "NH_(2))underset(|)(CH)-COOH`
(a) It is an `alpha` amino acid.
(b) It is a basic amino acid because number of `NH_(2)` groups (2) is greater than number of `COOH` group (1).
(c) It is a non-essential amino acid. Because it is synthesised in our body.
