WebCatalysts, Biological. biocatalysts, substances formedin living cells that accelerate (positive catalysis) or slow down (negative catalysis) the chemical processes in the body. Biologi-cal catalysts include primarily catalysts of a protein nature, theenzymes. WebCatalyst is a term derived from Greek καταλύειν, meaning “to annul,” or “to unite,” or “to pick up.”. Meanwhile, the concept of catalysis was first researched by chemist Elizabeth Fulhame and it was described in her book in the year 1794. This book content was based on her work in oxidation-reduction experiments.
