Life, declared Professor Willstätter at the Chicago symposium, is definitely a chemical process to which the pass key is the study of enzymes. Enzymes are catalytic substances produced by living cells. There are a multitude of them and each has an individual affinity for substances which it can either break down or synthesize...
Professor Willstätter's method of segregating enzymes is beautifully simple. The enzymes are colloids. White clay (kaolin) filters absorb certain kinds of colloids, alumina filters certain other kinds. Enzymes, which pass through both alumina and clay filters, have a third set of characteristics. By shrewd use of colloidal physics and chemistry Professor Willstatter segregated the three important enzymes of pancreatic fluid-lipase which acts on fats, amylase which acts on carbohydrates, trypsin which acts on proteins...
...chemists who heard Professor Willstätter in Chicago last week saluted him to the best of their ability. His enzyme work is the culmination of 43 able years in chemistry. He was the first to describe the exact molecular structure of cocaine and stropine, work which led to the synthesizing of many other drugs. He analyzed chlorophyll, the green coloring matter of all growing plants, and showed that chemically it is closely related to hematin, the coloring matter of blood...
...fundamental difference is iron in blood, magnesium in chlorophyll. For his chlorophyll investigations Professor Willstätter received the 1915 Nobel Prize for Chemistry...
