HPLC method development for chitin and chitosan valorisation chemistry

open access: yesCarbohydrate Polymer Technologies and Applications, 2021
Recently, chitin/chitosan chemistry is gaining huge attention to yield chemicals like oligomers, monomers, N-containing chemicals and furan derivatives. However, due to lack of proper analytical technique to separate them due to their almost similar size

Overview on Chitosan as a valuable ingredient and biostimulant in pharmaceutical industries and agricultural products [PDF]

open access: yesTrakia Journal of Sciences, 2017
Chitosan is a polysaccharide extracted from the shells of crustaceans, such as shrimp, crab, and cell walls of fungi. Chitosan is formed from chitin, a co-polymer of N-acetyl-D-glucosamine and D-glucosamine, when over 80% of the acetyl groups of the N ...

Type III Secretion Effectors with Arginine N-Glycosyltransferase Activity [PDF]

open access: yes, 2020
Type III secretion systems are used by many Gram-negative bacterial pathogens to inject proteins, known as effectors, into the cytosol of host cells. These virulence factors interfere with a diverse array of host signal transduction pathways and cellular
