Concept explainers
(a)
Interpretation: The number of different primary structures possible for a four-amino-acid segment of a protein, if the segment contains three glycine units and one alanine unit 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 one glycine, one alanine, one valine, and one cysteine unit 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.
