This article presents a comprehensive comparative study of chitosan extracted from Apis mellifera (honeybee) and fungal (Agaricus bisporus) sources. It explores their structural characteristics, physicochemical properties, and biomedical applicability. Using FTIR, UV-vis spectroscopy, SEM, and XRD analyses, as well as evaluations of degree of deacetylation (DDA), solubility, and antimicrobial activity, the article identifies key similarities and differences. This study supports tailored applications of each chitosan type in targeted biomedical fields.
