Concept explainers
(a)
Interpretation: The validation about the classification of lysine 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 glycine 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 Glu 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 Met as an essential amino acid has to be stated.
Concept introduction: The standard amino acids those are required for the synthesis of protein is called essential amino acids. The human body cannot synthesise the essential amino acids, so they should be taken through diet.
