Peptides and Proteins in a Conjugated Protein,a Prosthetic Group Is:
Peptides and proteins In a conjugated protein,a prosthetic group is:
A)a fibrous region of a globular protein.
B)a nonidentical subunit of a protein with many identical subunits.
C)a part of the protein that is not composed of amino acids.
D)a subunit of an oligomeric protein.
E)synonymous with "protomer."
Peptides and proteins Prosthetic groups in the class of proteins known as glycoproteins are composed of:
Working with proteins For the study of a protein in detail,an effort is usually made to first:
A)conjugate the protein to a known molecule.
B)determine its amino acid composition.
C)determine its amino acid sequence.
D)determine its molecular weight.
E)purify the protein.
