Draw the peptide that consists of glutamine, tyrosine, and valine, with tyrosine as the C-terminus and valine as the N-Terminus. What is the ful name of this peptide?
On paper draw a dipeptide, clearly showing the peptide bond joining the two amino acids together. If the two amino acids are valine and threonine, predict the overall charge of the dipeptide at pH 7. Do not forget to consider the amino (N-terminal) and carboxy (C-terminal) of the dipeptide, as well as the R groups. Select one: a. +2 b. -2 c. 0 d. -1 e. +1
The primary structure of a protein is formed by the condensation of amino acids in a certain sequence. Consider the dipeptide formed by the condensation of glycine and tyrosine in Figure 8.31B. a. Draw the structure of the dipeptide that would be formed if the two amino acids condensed in the opposite sequence. b. How are the structures of the dipeptides in Figure 8.31B and your drawing related to each other? B 0 HN-C-0--OH HO H-N-C-C-OH H CHE H OH...
HW Question: Draw the amino acids, lysine and valine joined by a peptide bond. Next, place a square around the peptide bond within the dipeptide molecule. Finally circle all the atoms which could interact with a water molecule.
Answer questions 7-8 please ! Draw a picture of two amino acids coming together to make a dipeptide. You may choose any two amino acids you like. Circle the peptide bond. What molecule is necessary to break a peptide bond?
Draw a peptide of two or more different amino acids. Circle the R group of each amino acid. Put a box around each peptide bond. Identify each amino acid with the one-letter code.
Suppose you have a peptide composed of 4 amino acids bonded together: glutamine, glycine, glutamic acid, and the novel amino acid friendsamine, which has an ionizable side group with a pKa of 5.9. At pH 7.0, this peptide has a net charge of -2. What is the charge on the protonated form of the friendsamine side group? Explain how you determined the charge on the protonated friendsamine side group
