Hyaluronic acid: a natural biopolymer with a broad range of biomedical and industrial applications.
TL;DR: An overview of the occurrence and physiological properties of HA, as well as of the recent advances in production biotechnology and preparation of the HA-based materials for medical application are presented.
The many ways to cleave hyaluronan.
TL;DR: In this review, the vast arrays of reactions that cause scission of hyaluronan polymers is presented, including those on an enzymatic, free radical, and chemical basis.
