Hydrogenation is a chemical process in which hydrogen gas is bubbled through a liquid oil in the presence of a catalyst, often a reactive metal such as platinum or nickel. The resulting reaction forces unsaturated fatty acids to accept additional hydrogen atoms and become at least partially saturated.
Blood fractionation refers generally to the process of separation using a centrifuge (centrifugation), after which three major components can be visualized: plasma, buffy coat and erythrocytes.ractionation makes it possible to isolate more than two components in a mixture in a single run. This property sets it apart from other separation techniques.
