1. Explain why polyaspartatic acid (a peptide containing only aspartic acid residues) does NOT form an alpha helix at pH 7.0 but can at pH 2. 6. 2. What kind of non-covalent interaction would the following pairs of amino acids have in the three dimensional structure of a protein at pH 7.0? a) His-Asp b) Tyr-Asp c) Val-Leu d) Trp-Gln 3. Explain how the difference in structure of hemoglobin and myoglobin contribute to their different functions.
QUESTION 12 What is the function of a peptide bond? A peptide bond is responsible for the secondary structure of a protein. To join the amino group of one amino acid to the carboxy group of another amino acid, A peptide bond is responsible for the tertiary structure of a protein A peptide bond joins the phosphate group at the 6 carbon of a new nucleotide to the hydroxyl (OH) group of the 3' carbon of a nucleotide already in...
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?
