“…1,2 Despite being extracted from natural sources, this polymer has other advantageous properties, such as its low toxicity, weak antigenicity, high nutritional value, and exibility, as well as its biodegradability and biocompatibility. 3,4 Its extraction from mammalian sources, i.e., bovines, is decreasing due to health and environmental problems, 5 and, therefore, sh has become a good alternative collagen source. In fact, the decrease in collagen extraction in land animals can be explained by the possible human infections resulting from the outbreak of diseases in stock animals.…”
