Minimum molecular weight ratio

The minimum molecular weight ratio determined by Ffannkoch et al. (6) In a direct comparison of high performance SEC columns. 

Conversion of the relative ratios of amino acids into an estimate of actual composition requires some additional information concerning the protein s molecular weight for example, an analysis giving relative ratios of Ala (1.0), Gly (0.5), and Lys (2.0) could correspond to composition Ala2-Gly-Lys4 or any multiple thereof. The required information is usually available, and in any case, an estimation of composition based on a minimum molecular weight of the protein is always possible.

The maximum specific impulse lies at a mixture ratio between the mixture ratios of minimum molecular weight and maximum combustion temperature. Pc = 1000 psia, optimum equilibrium expansion to one atmosphere ambient pressure...

When total iron and non-heme iron in adrenodoxin were determined with o-phenanthroline all the iron existed as non-heme iron and was extractable with 5% trichloroacetic acid. The ratio of iron to protein on a biuret basis was 109 mp. atoms of iron per mg of protein. Based on the dry weight of adrenodoxin, the ratio was 147 mp. atoms of iron per mg protein. The minimum molecular weight per iron atom would be 6,800. 

NADPH-cytochrome P-460 reductase is composed of a single polypeptide chain of 70,000-80,000 molecular weight 369, 371, 373, 374) associated with one molecule of FAD and one molecule of FMN 370, 371, 373, 378, 379). These results apply to the enzyme whether solubilized by proteolytic digestion or by detergent extraction. The minimum molecular weight based on the flavin content is somewhat higher, 87,000 (373), possibly indicative of the flavin lability observed upon irradiation in ammonium sulfate 380). The detergent-solubilized reductase has a lower flavin content, 0.64 and 0.79 moles of FMN and FAD per 79,000 g of enzyme 371). The absorbance ratio, 275 nm 455 nm of 6.5, indicates a relatively low content of aromatic amino acids 373, 374) The extinction of the flavins at 455 nm is 10.7 mM cm" (373).

It has been reported by Lewis et al. [1] that the equivalence ratio where the minimum ignition energy has a minimum is dependent on the fuel property for hydrocarbon fuel and air mixtures, and that it moves to the rich side as the molecular weight of the fuel increases. This equivalence ratio dependency has been explained by the preferential diffusion effect. 

The value in units of incident dose per unit area for either a positive or negative resist system is of little value unless accompanied by a detailed description of the conditions under which it was measured. This description should include, at the minimum, the initial film thickness, the characteristics of the substrate, the temperature and time of the post- and pre-bake, the characteristics of the exposing radiation, and the developer composition, time and temperature. The structure, copolymer ratio, sequence distribution, molecular weight, and dispersity of polymers included in the formulation should also be provided.
