Concept explainers
(a)
Interpretation: The number of different primary structures possible for a four-amino-acid segment of a protein, if the segment has no restrictions on the amino acids that can be present has to be stated.
Concept introduction: The primary protein structure is the order of linking of the amino acids in proteins. The primary protein structure includes the number of amino acids linked, kind of amino acids present and the order of attachment of amino acids.
(b)
Interpretation: The number of different primary structures possible for a four-amino-acid segment of a protein, if the segment contains two each of two different amino acids has to be stated.
Concept introduction: The primary protein structure is the order of linking of the amino acids in proteins. The primary protein structure includes the number of amino acids linked, kind of amino acids present and the order of attachment of amino acids.
