If two amino acids are combined with a peptide bond, how would you describe the structure? 000 Dipeptide Protein Amide Polypeptide E vy

Draw the peptideTyr-Gly-Gly-Phe-MetClassify the peptideDipeptide, Tripeptide, Polypeptide or ProteinGive the name of the peptide • Using amino acid name

A peptide has the sequence Ala-Phe-Glu-Lys-Asp-Pro-Asp. What charge will it carry at physiological pH? Show your calculation.

What is a peptide bond? a covalent bond formed when the carboxyl group of one molecule reacts with an amino group of a different molecule an ionic bond formed when a nitrogen atom in one molecule reacts with a carbon atom in a different molecule an ionic bond formed when the hydroxyl group of one molecule reacts with an amino group of a different molecule a covalent bond formed when a nitrogen atom in one molecule reacts with an oxygen atom in a different molecule

Draw the tripeptide described by Phe-Trp-Cys. Your drawing can be a Lewis structure

Answer the questions in the table below about this molecule: H3N CH COO CH3 CH CH3 What kind of molecule is this? If you said the molecule is a peptide, write a description of it using 3-letter codes separated by dashes. ☐ monosaccharide lipid peptide amino acid none of the above

QUESTION 9 The following diagram attached shows 2 molecular structures of amino acids, alanine (Ala) and threonine (Thr). Based on the structures, draw the dipeptides of Thr-Ala and circle the peptide linkage.

e ntifying and drawing peptide bonds Highlight each peptide bond in the molecule below. In addition, list the common names of the smaller molecules that would bê released if all the peptide bonds were hydrolyzed. You can add more rows to the table if you need to. (Note: you do not need to list water.) If there are no peptide bonds in the molecule, just check the no peptide bonds box below the drawing area.
