Question

What$\mathrm{\alpha }$-halo carbonyl compoundis needed to synthesize each amino acid?

(a) Glycine

(b) Isoleucine

(c) Phenylalanine

Short answer

Answer

a.

b.

c.

Step-by-step solution

Step  1: α-halocarbonyl compound

$\mathbf{\alpha }$-halo carbonyl compound are compound that contain keto-group or $\mathbf{\alpha }$-halogen substitute in a carbonyl group. $\mathrm{\alpha }$-halo carbonyl compound acts as alkylating agents.

Step 2:Amino acids

Amino acids are classified as organic molecules that are accountable for protein formation when combined. It has carbonyl (acidic) and amino (basic) groups with a side (-R) chain.

Reaction

(a) When bromoacetic acid is treated with NH₃in excess amount, it forms glycine.

Formation of glycine

b. When C₉H₉O₂Br is treated with NH₃in excess amount, it forms isoleucine

(c) When 6-bromohexanoic acid is treated with NH₃in excess amount, it forms phenylalanine.
