Even if only a single C C bond of the polymer chain in UHMWPE is broken and two.CH2– radicals are formed, the molecular mass decreases; as a consequence, many of the chemical and physical properties of the polymer begin to worsen.
Alternatively, the apparent molecular mass would decrease by 14 Da if a given amide is reduced to a primary amine.
In theory, the apparent molecular mass would decrease by 16 or 14 Da if a given carboxylic acid is reduced to an aldehyde or an alcohol, respectively.
The predictions for the effect of dilution are that, if a reversible dimer is present, the Kd value estimated will be the same, but the average molecular mass will decrease markedly.
However, an increase in the length scale for nanoconfinement was observed as the molecular mass was decreased below this threshold.
In contrast, neuroserpin immunoprecipitated from PC12-G392E cells ran as a single band of higher molecular mass that decreased in size following treatment with endoglycosidase H (Fig. 4B, G392E −/+).
In fact, in αA1 162 the secondary and tertiary structures were significantly altered and the molecular mass was substantially decreased [16].
One study, using a radiosorbent assay with large quantities of whole tissue, reported that the molecular mass of HA decreased and the concentration increased with increasing age [ 20].
As shown in Figure 5(B), in the presence of either Hxk2 or Hxk2wca proteins, Mig1 from low-glucose grown cells displays a slight shift in molecular mass, resulting in decreased mobility, in comparison with Mig1 from high-glucose-grown cells.
The seadornavirus genome consists of 12 segments of dsRNA known as Seg-1 to Seg-12 in order of decreasing molecular mass observed by gel electrophoresis.
The results showed a significant decrease in the permeability with decreasing the molecular mass.
