WebChitosan is a long-chain sucrose polymer, structured much like polyester (of all things!). It’s not a protein at all, so it can’t provoke an allergic reaction of any sort. (Allergic reactions are the immune system response to the presence of foreign protein chains. No protein chain, no reaction). WebJan 15, 2024 · The elaborated catalytic systems efficiently catalyze the aforementioned reactions in the greenest solvent available, i.e., water, and the processes could be conducted in air. The studied...
