Protein Structure A protein contains a string of amino acids (usually more than 50) that has a biological function. 15ecause proteins are so large, their structure has several levels, all of which are important for the proper functioning of the protein. Ultimately, the sequence of amino acids (ordering of polar and nonpolar amino acids) dictates the 3-dimensional shape of a protein and this dictates its primary function. Level 1: Primary (1") The amino acid sequence of a polypeptide Protein Backbone...

Examine the polypeptide in its major ionization state at pH 1.
-How many amino acids are present in this peptide?
**Can you please circle them and label? I'm having a
hard time identifying where they are. The chart I have seems off
from what I see here.
-Also, at what pH in an isoelectric focusing gel
should you look for this purified peptide? Explain.
Thanks for the help!
