I need help with biochem. i have an exam tomorrow, and i'm having a problem with calculating the lengths of polypeptides. so here's question 1.
Calculate the length in nanometers of a polypeptide chain containing 105 a.a. recidues if a) it exists entirely in alpha helical form, or b) if the backbone bonds are fully extended and linear.
question 2:
The polypeptide chain of a given protein is alpha-helical in some segments and has the beta conformation in others. The protein has a MW of 240,000 and a contour length of 506 nm. Calculate the fraction of the molecule that exists in the alpha helical configuration.
i think i'm ok with everything else, but for some reason, how to calculate the lengths appears to elude me.
