Donald Dexter Van Slyke(March 29, 1883 – May 4, 1971), nicknamedVan,was aDutch Americanbiochemist.His achievements included the publication of 317 journal articles and 5 books,[1]as well as numerous awards, among them theNational Medal of Scienceand the firstAMA Scientific Achievement Award.[1]TheVan Slyke determination,a test of amino acids, is named after him.[2]
Early days and education
[edit]Van Slyke was born inPike, New Yorkon March 29, 1883. He completed his BA in 1905 and PhD in 1907 both at theUniversity of Michigan,his father's alma mater.[1]His PhD studies were performed underMoses Gomberg.[1]
Post-doctoral study
[edit]Van Slyke took up apost-doctoralposition at theRockefeller Institutein 1907, underPhoebus Levene.Levene also arranged for him to spend one year inBerlinunderHermann Emil Fischerin 1911.[1]His early work focused on determining theamino acidcomposition ofproteins.A major achievement during this time was the discovery of the amino acidhydroxylysine.[3]
Urease
[edit]Work with G. E. Cullen on urease[4]led to a mechanism that yields a kinetic equation observationally indistinguishable from the Henri–Michaelis–Menten equation, but based on different assumptions. Whereas Henri,[5]and later Michaelis and Menten,[6]treated the binding of substrate to free enzyme to produce an enzyme–substrate complex as an equilibrium, Van Slyke and Cullen treated it as an irreversible reaction:
Enzyme + substrate → enzyme–substrate complex → enzyme + product
Effectively, therefore, they assumed a steady-state process.[7]Their equation for the rateat substrate concentration,
resembles the Henri–Michaelis–Menten equation but the constantin the denominator is interpreted differently.
Clinical chemistry
[edit]In 1914, Van Slyke was appointed chief chemist of the newly founded Rockefeller Institute Hospital, where he played a key part in developing the field ofclinical chemistry.[8]His work focused especially on the measurement ofgasandelectrolytelevels intissues,[1]for which he is considered to be one of the founders of modern quantitative blood chemistry.[8]He is also considered by many to have first popularised the term "clinical chemistry" in his two-volume workQuantitative Clinical Chemistry,co-published withJohn P. Peters.The two-volume work was widely accepted in the medical world as the"Bible"of quantitative clinical chemistry.[1]During this period, he also served as managing editor of theJournal of Biological Chemistryfrom 1914 to 1925.
Brookhaven
[edit]In 1948, approaching retirement age, Van Slyke took up a position as deputy director of biology and medicine of the newly-formedBrookhaven National Laboratory.He held this position briefly before moving back into research at Brookhaven, which he continued until his death in 1971.[1]
