A descriptor of average shape features of macromolecules, polymers, and proteins, i.e. it can be considered as a measure of the degree of folding, defined as [Arteca, 1991] ... 

Figure 4 Effect of degree of glycosylation on protein biophysics, (a) The effect of degree of glycosylation on thermal stability as measured either by the change in TF relative to the unmodified protein (ArF=(TF lycosylated-TFunslycosylated)/rFun l) cos) lated) or by the degree of folding (calculated at the temperature at which the folded state of the unmodified protein is 50% populated), (b) The effect of degree of glycosylation on the size of folded and unfolded conformations.

The nature of the lowest electronic states of the chalcogenanthrenes has been studied, as have singlet-triplet transitions in the excited states <89MI 624-01 >. In the latter case singlet-triplet radiative transitions are influenced by the nature of the heteroatoms present, and nonradiative processes are dominated by the degree of folding <77JCPBI177>. 

X-ray crystal structure determinations have been carried out on a limited number of P/O heterocycles. 10-Phenylphenoxaphosphine (265) was confirmed to be nonplanar by this method the molecule is folded along the P" 0 axis, and the phosphorus atom is nonplanar <76JCS(P2)1383>. The cation of 2,4,4,6-tetraphenyl-1,4-oxaphosphininium perchlorate (266) is described as quasi-planar, although a small degree of folding is evident <74CSC227>.

In the much-studied E. coli cell, the closed circular DNA has a molecular weight of 2.6 x 10 with about 4 x 10 base pairs and a contour length (i.e. when stretched out) of about 1.4 mm. A considerable degree of folding and supercoiling of the DNA is implied since the cell diameter is only 0.002 mm. 

D/D matrix offers good characterization of the degree of folding of such structures. The element i, j) of the D/D matrix is defined as...
