Question
A short peptide on complete hydrolysis produces 33 moles of glycine (G)G, two moles of leucine (L)L and two moles of valine (V)V per mole of peptide. The number of peptide linkages in it are _____ .
Solution
The number of peptide linkages in a peptide is always one less than the number of amino acids present. This is because each peptide linkage is formed by the condensation of two amino acids.
From the question, we know that the peptide produces 33 moles of glycine, 2 moles of leucine, and 2 moles of valine upon complete hydrolysis. This means that there are 33 + 2 + 2 = 37 amino acids in the peptide.
Therefore, the number of peptide linkages in the peptide is 37 - 1 = 36.

Under physiological conditions, peptide bond formation requires coupling to GTP hydrolysis. Peptide bond degradation does not require GTP hydrolysis but does require a protease enzyme to proceed at physiologically relevant rates. Based on this information, under physiological conditions and in the absence of proteases, the peptide bonds that form during protein synthesis are:A.both thermodynamically and kinetically stable.B.thermodynamically unstable but kinetically stable.C.thermodynamically stable but kinetically unstable.D.both thermodynamically and kinetically unstable.
