Britton Chance Dies

Britton Chance, who developed tools for studying enzymatic activity and studied the mitochondria, died, reports the Los Angeles Times. He was 97. In the 1940s, Chance came up with stopped-flow spectrophotometry to study enzyme reactions rates and developed the Theorell-Chance mechanism, which says the rate of a reaction is governed by how quickly products are released from the reaction complex. Later, he studied mitochondria, developing a dual wavelength spectrophotometer and a fluorescent spectrophotometer to aid that work. The LA Times also notes that Chance was an Olympic sailor, taking the gold medal in the 1952 Helsinki Games.
