Chemistry:Contact number
From HandWiki
In chemistry, a contact number (CN) is a simple solvent exposure measure that measures residue burial in proteins.[1] The definition of CN varies between authors, but is generally defined as the number of either C[math]\displaystyle{ \beta }[/math] or C[math]\displaystyle{ \alpha }[/math] atoms within a sphere around the C[math]\displaystyle{ \beta }[/math] or C[math]\displaystyle{ \alpha }[/math] atom of the residue. The radius of the sphere is typically chosen to be between 8 and 14Å.
