Chapter 29: Q42. (page 1193)

Devise a synthesis of each amino acid from acetaldehyde:

(a) Glycine;

(b) Alanine.

Short Answer

Expert verified

Amino acid plays a vital role in body functions such as tissue repairing, digesting food, and enzyme formation.It is a white crystalline solid that dissolves in water.

Step by step solution

01

Amino acid

Amino acid plays a vital role in body functions such as tissue repairing, digesting food, and enzyme formation.It is a white crystalline solid that dissolves in water.

02

Synthesis of amino acid

(a) When acetaldehyde is treated with bromine followed by acetic acid, it gives acetyl bromide. Acetyl bromide is then treated with CrO3followed by sulphuric acid, and it gives bromoacetic acid which on further treatment with excess of NH3forms glycine.

(b) When acetaldehyde is treated with ammonium chloride and sodium cyanide, followed by hydrolysis, alanine is formed.

What is the predominant form of each of the following amino acids at pH=11? What is the overall charge on the amino acid? (a)valine; (b)proline; (c)glutamic acid; (d)lysine?

Draw all the steps in the synthesis of each peptide from individual amino acids:

  1. Gly-Ala;

  2. Ile-Ala-Phe

Give the amino acid sequence of each peptide using the fragments obtained by partial hydrolysis of the peptide with acid.

  1. A tetrapeptide that contains Ala, Gly, His, and Tyr, which is hydrolyzed to the dipeptides His-Tyr, Gly-Ala, and Ala-His.
  2. A pentapeptide that contains Glu, Gly, His, Lys, and Phe, which is hydrolyzed to His-Gly-Glu, Gly-Glu-Phe, and Lys-His.

Outline the steps needed to synthesize the tetrapeptideAla鈥揕eu鈥揑le鈥揋ly using the Merrifield technique.
