We investigated the effects of bioactive-peptides from hydrolysates of flounder fish muscle (FFM) on antioxidant activity. The hydrolysates were prepared by enzymatic reactions of FFM using eight commercial proteases such as papain, pepsin, trypsin, neutrase, alcalase, kojizyme, protamex, and α-chymotrypsin.

Tools for Performing ATRP

A Micro Review of Reversible Addition/Fragmentation Chain Transfer (RAFT) Polymerization

We presents an article about a micro review of reversible addition/fragmentation chain transfer (RAFT) polymerization. RAFT (Reversible Addition/Fragmentation Chain Transfer) polymerization is a reversible deactivation radical polymerization (RDRP) and one of the more versatile methods for providing living characteristics to radical polymerization.

Copper(I)-mediated Living Radical Polymerization in the Presence of Pyridylmethanimine Ligands

We presents an article about Copper(I)-mediated Living Radical Polymerization in the Presence of Pyridylmethanimine Ligands, and the emergence of living radical polymerization mediated by transition metal catalysts in 1995, which was a seminal piece of work in the field of synthetic polymer chemistry.
