Question

Which of the amino acids contain the following functional groups in their R group?

a. alcohol c. amine

b. carboxylic acid d. amide

Short answer

(a)Aminoacids containing alcohol group are tyrosine, serine and threonine

(b)Amino acids containing carboxylic group are aspartic and glutamic acids

(c) Amino acids that contain amine group are histidine, lysine, arginine and tryptophan

(d) Asparagine and glutamine have amide groups.

Step-by-step solution

To find the amino acid contain Alcohol

Alcohols are amino acids containing - OH functional group. In the picture below, amino acids containing – OH group are listed. They are in order of tyrosine, serine and threonine.

Hence Amino acids containing alcohol group are tyrosine, serine and threonine

To find the amino acid contain carboxylic acid      

Aspartic and glutamic acids areamino acids containing carboxylic groups.Carboxylic groups are marked with red color. See the picture below.

Hence Amino acids containing carboxylic group are aspartic and glutamic acids.

To find the amino acid contain Amine

Histidine, lysine, arginine and tryptophan are amino acids containing amine groups. Amine groups are marked with red color. See the picture below.

Hence amino acids that contain amine group are histidine, lysine, arginine and tryptophan

To find the amino acid contain Amide

Asparagine and glutamine are amino acids containing amide groups. Amide groups are marked with red color. See the picture below.

Hence Asparagine and glutamine have amide groups.
