WebSep 10, 2024 · First, cellulose and chitin have similar structures; the only difference is the presence of an N -acetyl amino group instead of a hydroxyl group on C-2 in cellulose. Consequently, chitin and cellulose are miscible and the resulting materials have improved properties benefiting from both polymers. WebRoughet discovered that chitin could be transformed into a water-soluble form after chemical modiﬁcation [19]. In 1894, this chemically modiﬁed chitin was called chitosan by Hoppe-Seyler [29,30]. Although chitin was discovered 30 years before cellulose, most of the research was focused on cellulose, due to the high investments made by the ...
