Researchers first developed the free radical scavenger edaravone in late 1980s as a treatment for stroke. The approach, introduced by Koji Abe, now at Okayama University Hospital in Japan, aimed to prevent the swelling of the brain which may occur after a stroke.
In peptide synthesis, TIPS is used as a scavenger for peptide groups being removed from the peptide sequence at the global deprotection. TIPS is able to scavenge carbocations formed in the deprotection of a peptide as it can act as a hydride donor in acidic conditions. [1] Silanes may be preferred as scavengers in place of sulfur-based scavengers.
The introduction of protein-based cross-links, [59] the introduction of free-radical scavenging molecules such as sorbitol, [60] and minimal stabilisation of the HA chains through chemical agents such as NASHA (non-animal stabilised hyaluronic acid) [61] are all techniques that have been used to preserve its shelf life.

The radical cyclization step usually involves the attack of a radical on a multiple bond. After this step occurs, the resulting cyclized radicals are quenched through the action of a radical scavenger, a fragmentation process, or an electron-transfer reaction. Five- and six-membered rings are the most common products; formation of smaller and ...
Living free radical polymerization is a type of living polymerization where the active polymer chain end is a free radical. Several methods exist. Several methods exist. IUPAC recommends [ 1 ] to use the term " reversible-deactivation radical polymerization " instead of "living free radical polymerization", though the two terms are not synonymous.
Jennifer Aniston says Pvolve fitness “transformed” her body without causing pain. She also shared how she ignores “bullsh*t” aging rules at 55.
The Basics of Losing Weight After 40. Losing weight can be challenging at the best of times. But after the big 4-0, a few more challenges pop up, making weight gain common and weight loss harder.
The heart-healthy benefits of walking and other cardio workouts are well-known. But new research shows another type of exercise may be beneficial. Specifically, exercise focused on building muscle ...
