Molecular weight cut off (MWCO): Mean pore radius of the membrane can be measured by rejection test using solute of higher molecular weight compound (such as PEG and polyethylene oxide; PEO). According to Stokes-Einstein equation, stokes radius (a) of a macromolecule can be found from its ...
In NMR spectroscopy they allow to establish precise correlations between various groups of a macromolecule, leading to “structural constraints” that convey useful complementary information to data obtained by other structural methods such as X-ray or neutron scattering methods, described below. Even ...
14 Besides, chitosan mucoadhesives are limited in their ability to “unload”, since a large proportion of the bioactive molecule remains trapped in the mucus/chitosan complex and is passed along the alimentary canal. Thiomers or thiolated polymers are an example of a more recent development of...
One pertinent example is the management of type 1 diabetes, a chronic disease affecting 18 million people worldwide, with an annual economic burden of greater than $90 billion USD (Study: Disease-Modifying Therapies Needed to Offset Costs of Type 1 Diabetes - Juvenile Diabetes Research Foundation)...
it is striking that most of the best hit homologs of enzymes of central metabolism are proteins ofV. cholerae. This is particularly puzzling sinceV. choleraeis a mesophile and it is phylogenetically in a different Order and Family fromP. ingrahamii. Could this be an example of massive horizont...

Recent Discoveries of Macromolecule- and Cell-Based Biomarkers and Therapeutic Implications in Breast Cancer. Int. J. Mol. Sci. 2021, 22, 636. [Google Scholar] [CrossRef] Taneja, P.; Maglic, D.; Kai, F.; Zhu, S.; Kendig, R.D.; Fry, E.A.; Inoue, K. Classical and Novel ...
sulfation of OH groups of β-aryl ethers of the lignin macromolecule in the γ position. In addition, free OH groups in the α position of β-aryl ethers (A) are probably subjected to the sulfation, since the Cα-Hαpeak at δC/δH72.5/4.88 ppm is missing in the sulfated lignin ...
aProtein has a large number of important functions in the human body—and in fact, the human body is about 45% protein. It’s an essential macromolecule without which our bodies would be unable to repair, regulate, or protect themselves. 蛋白质有很大数量的重要作用在人身体和实际上,人体是...
What is an example of transfer RNA?Uses of RNA:There are three types of RNA molecules, each of which plays a different role in the synthesis of proteins. All the RNA molecules are made using a DNA template and have relatively short lifespans which means a cell can control protein ...
