Interpretation:
The amino acid responsible for the permanent wave in hair needs to be determined.
Concept introduction:
The amino acid is termed as the monomer of proteins. The peptide linkage and other hydrogen bonds make it stable and tensile. Different types of proteins play an important role in the human body. Hair, nails, muscles and other contains a major quantity of proteins.
Answer to Problem 49A
Cysteine amino acid is responsible for the permanent wave in hair.
Explanation of Solution
The sulfur-containing protein is cysteine composed of tertiary structure and it forms a dimer with the help of disulfide linkage. The dimer of cysteine form wave in hair.
