Английская Википедия:Donald Van Slyke
Шаблон:Short description Шаблон:Infobox scientist Donald Dexter Van Slyke (March 29, 1883 – May 4, 1971), nicknamed Van, was a Dutch American biochemist. His achievements included the publication of 317 journal articles and 5 books,[1] as well as numerous awards, among them the National Medal of Science and the first AMA Scientific Achievement Award.[1] The Van Slyke determination, a test of amino acids, is named after him.[2]
Early days and education
Van Slyke was born in Pike, New York on March 29, 1883. He completed his BA in 1905 and PhD in 1907 both at the University of Michigan, his father's alma mater.[1] His PhD studies were performed under Moses Gomberg.[1]
Post-doctoral study
Van Slyke took up a post-doctoral position at the Rockefeller Institute in 1907, under Phoebus Levene. Levene also arranged for him to spend one year in Berlin under Hermann Emil Fischer in 1911.[1] His early work focused on determining the amino acid composition of proteins. A major achievement during this time was the discovery of the amino acid hydroxylysine.[3]
Urease
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 rate <math>v</math> at substrate concentration <math>a</math>,
<math>v = \frac{Va}{k_2/k_1 + a}</math>
resembles the Henri–Michaelis–Menten equation but the constant <math>k_2/k_1</math> in the denominator is interpreted differently.
Clinical chemistry
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 of clinical chemistry.[8] His work focused especially on the measurement of gas and electrolyte levels in tissues,[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 work Quantitative Clinical Chemistry, co-published with John 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 the Journal of Biological Chemistry from 1914 to 1925.
Brookhaven
In 1948, approaching retirement age, Van Slyke took up a position as deputy director of biology and medicine of the newly-formed Brookhaven National Laboratory. He held this position briefly before moving back into research at Brookhaven, which he continued until his death in 1971.[1]
