molecular weight of a complex mixture such as crude oil even if the molecular constituents are not of the same type and exist in different sizes.Molecular weightis often used in refineries to provide mass-average ornumber-average measurements. Consequently a number of methods are available to ...
Molecular weight of chitosan can be determined by different techniques such as Gel Permeation Chromatography (GPC), Static Light Scattering (SLS) and intrinsic viscosity measurement. Determination of molecular weight by intrinsic viscosity measurement is a simple method for characterization of chitosan. Dif...
Molecular Weight The molecular weight of a polymer is of prime importance in the polymer’s synthesis and application. Chemists usually use the term molecular weight to describe the size of a molecule. The more accurate term is molar mass, usually in units of g mol-1. The interesting and ...
The Molecular Weight Calculator is a physics/math tool designed to find the average molecular weight (MW) of molecules by inputting their chemical formulas. Fe…
The set is based on the ZINC Clean Leads collection. It contains 4,591,276 molecules in total, filtered by molecular weight in the range from 250 to 350 Daltons, a number of rotatable bonds not greater than 7, and XlogP less than or equal to 3.5. We removed molecules containing charged...
One limitation of the method is the requirement for high quality, high molecular weight input DNA. This can be particularly challenging for plants that frequently contain common and species-specific secondary metabolites, which often interfere with downstream processes. Cape Primroses (genus Streptocarp...
With a molecular weight of 244 Da, biotin is similar in size and characteristics to many endogenous signaling molecules and metabolites, so we also anticipated that an imaging sensor for biotin could subsequently be adapted for detection of other targets. The tetrameric 53 kDa protein ...
Of note, the line width of an NMR signal is related to the molecular weight of the protein tumbling in solution. Thus, the line broadening observed during complex formation will reflect the increase in the molecular weight of the complex. In addition, the stability of the complex, that is,...
The distributions of linear and cyclic methylsiloxanes were determined by gas-liquid chromatography during acid clay catalyzed reactions of equal molar amounts of D4 [D = (CH3)2SiO] and MM [M = (CH3)3SiO1/2] at 80°. The theoretical and experimental distributions of the linears are comp...
Bioinformatic analyses Vector NTI Suite 7 [20] was used for ORF translation and molecular weight calculation of the deduced protein. BLAST [21] was performed on the NCBI server (http:// www.ncbi.nlm.nih.gov/BLAST). Multiple sequence align- ments and phylogenetic analysis were carried out ...
