Concept explainers
(a)
Interpretation: The validation about the classification of valine as an essential amino acid has to be stated.
Concept introduction: The standard amino acids which are required for the synthesis of protein are called essential amino acids. The human body cannot synthesise the essential amino acids, so they should be taken through diet.
(b)
Interpretation: The validation about the classification of isoleucine as an essential amino acid has to be stated.
Concept introduction: The standard amino acids which are required for the synthesis of protein are called essential amino acids. The human body cannot synthesise the essential amino acids, so they should be taken through diet.
(c)
Interpretation: The validation about the classification of Trp as an essential amino acid has to be stated.
Concept introduction: The standard amino acids which are required for the synthesis of protein are called essential amino acids. The human body cannot synthesise the essential amino acids, so they should be taken through diet.
(d)
Interpretation: The validation about the classification of Pro as an essential amino acid has to be stated.
Concept introduction: The standard amino acids which are required for the synthesis of protein are called essential amino acids. The human body cannot synthesise the essential amino acids, so they should be taken through diet.
