Effect of Carboxymethylation on the Rheological Properties of Hyaluronan. [PDF]

PLoS ONE, 2016
Chemical modifications made to hyaluronan to enable covalent crosslinking to form a hydrogel or to attach other molecules may alter the physical properties as well, which have physiological importance. Here we created carboxymethyl hyaluronan (CMHA) with

The cytotoxicity of DNA carboxymethylation and methylation by the model carboxymethylating agent azaserine in human cells [PDF]

Carcinogenesis, 1999
Carboxymethylating agents are potential sources of endogenous DNA damage that have been proposed as possible contributors to gastrointestinal carcinogenesis. The cytotoxicity of the model DNA carboxymethylating agent azaserine was investigated in human cells.

Laser‐Induced Periodic Phase‐Transition of 2D‐MoTe2 Nanograting Template for Frequency‐Shift Digital‐SERS Immunoassay of Autoimmune Disease

Advanced Science, Volume 13, Issue 39, 13 July 2026.
A protocol of fs‐laser‐induced periodic phase‐transition of 2D‐MoTe2 template, inducing AuNPs@1T’‐MoTe2 nanograting, is developed. The labeled AuNPs@1T’‐MoTe2 substrate conjugated with specialized immunoglobulin G demonstrates an unexpectedly high discrimination accuracy close to unity for serological diagnosis of rheumatoid arthritis by frequency ...

Carboxymethylation of corn bran polysaccharide and its bioactive property

, 2017
Corn bran polysaccharides were extracted using an ultrasonic-assisted method with a yield of 33.50% and then carboxymethylated. The occurrence of modification was confirmed using Fourier transform infrared spectral analysis. The surface of polysaccharide

Mass Spectrometry and NMR Spectroscopy‐Based Structural Characterization of Polysaccharide From Gastrodia elata Blume

Food Frontiers, Volume 7, Issue 4, July 2026.
ABSTRACT Structural characterization of complex carbohydrates remains challenging. This study employed methylation, acid hydrolysis, 1‐phenyl‐3‐methyl‐5‐pyrazolone (PMP) derivatization, and ultra‐high performance liquid chromatography–tandem mass spectrometry (UHPLC–MS/MS) to determine monosaccharides, glycosidic linkages, and sequence of ...
