Part 1 (1 point) See Hint Due to its partial double bond character, the peptide bond restricts rotation, constraining atoms to lie within the same peptide plane. Rotation in the peptide backbone is around the two bonds that flank adjacent Ca atoms, between which a peptide plane is formed. Part 2 (1 point) See Hint What is the molecular geometry of the constituents of the peptide plane? Choose one: A. The amide nitrogen is tetrahedral and the carbonyl carbon is...

Which of the statements about peptide bonds are true? D A tripeptide contains three amino acid residues. Peptide bonds are ester linkages. Peptide bond formation is a hydrolysis reaction. O Peptides are polymers of amino acids. Peptide bonds form from nucleophilic attack by an a-carboxyl carbon atom on an electron pair of an a-amino nitrogen atom of another amino acid.

Draw the following peptide tyrosine-cysteine-lysine-leucine. Identify the functional groups of the side chains by name and label the peptide bonds, the N-terminus, and the C-terminus of the peptide. Also, what is the one letter code? Draw the membrane lipid phosphatidylserine with stearic acid and oleic acid attached to the glycerol-3-phosphate backbone in position 1 and 2, respectively. How are the individual parts of the molecule (glycerol, phosphate, serine, and fatty acids) connected to each other?

Calculate the net charge on the following peptide that contains an intramolecular disufide bond at pH 12. Assume that the peptide and disulfide bonds are stable at this pH. This question does not require you to draw the structure of this peptide, only to calculate the appropriate charge. You must identify where each charge comes from; you can't just give a final net charge number. Show all your work to obtain any-credit. (8 pts) QUESOn Calculate the net charge on...
