9.1 Molecular Weights The molecular weight (or relative molecular mass) of a substance is the mass of its molecules relative to that of other molecules. The datum for molecular weights is carbon-12, and this is given a molecular weight of 12. All other elements and compounds have molecular ...
Glycinin, the major soyabean globulin, is composed of subunits having molecular weights of about 22,300, and 37,200. On the basis of amino acid analysis, the six submits of glycinin isolated by isoelectric focusing are all different. The acidic subunits have higher content of glutamic acid ...
The calculated (or predicted) molecular weight of a protein is determined by adding the actual molecular weights of individual amino acids in a given protein. The calculated molecular weight is occasionally different from that observed on the western blot. Several fac...

Molecular Weight (Polymers) refers to the sum of the atomic weights of individual atoms in a polymer molecule, indicating the average length of the polymer chains in the bulk resin. It can be calculated using number average molecular weight (Mn) or weight average molecular weight (Mw). ...

The molecular weights of the protein bands were determined using Kapelan GmbH’s Lab Image software version 2.7. ISSR amplification and electrophoresis Total genomic DNA was extracted from 100 mg of young pea young leaves using the Gene JET™ Plant Genomic DNA Purification Kit (K0721/Thermo ...
The molecular weights of the purified proteins were identified by MALDI-ToF MS spectrometer (Axima-TOF2TM, Shimadzu Biotech). A 1:1 ratio of sinapinic acid matrix (Sigma-Aldrich; 20 mg ml−1 and 1 μl) and the samples resuspended in 5% acetic acid (1 μl) were vortexed and...
In heated aqueous solutions of and alanine or , respectively, the majority of colored compounds formed were shown to have molecular weights < 1000 Da. Compounds with molecular weights > 3000 Da were found in only trace amounts, whereas high molecular colorants could not be observed under the co...
