Protein residues

[erby]

quick question regarding statistics for my biochem class:

i need to find degeneracy (W) for a half denatured protein of 100 residues.

Degeneracy is defined as the total number of isoenergetic possibilities.

So there are 99 bonds in a 100 residue protein. Half of them will be denatured. A denatured bond has 4 different possible orientations.

So basically you have 99 spots, so half denatured would be 49.5 of the bonds, each bond could be 1 of 4 orientations, and appear anywhere in the 99 spots. How many different combinations could there be?
