Question

The total number of basic groups in the following form of lysine is:

• A. 0
• B. 1
• C. 2
• D. 3
• E. 4
• F. 5
• G. 6
• H. 7
• I. 8
• J. 9

Answer 1

The correct option is C 2

$-\stackrel{O}{\stackrel{||}{C}}-O^{⊝}$ and $-N{H}_2$ are basic groups in lysine.

Lysine group is an - amino acid with the chemical formula $H{O}_{2}CCH\left(N{H}_2\right)(C{H}_2{)}_{4}N{H}_2$.
