Bertrand introduced into biochemistry both the term “oxidase” and the concept of trace elements.
The laccase, a polyphenol oxidase and an enzyme oxidating urishiol and laccol obtained from the lacquer tree, was first studied by Gabriel Bertrand[1] in 1894.
[3] In 2005, Raubenheimer et al. fed excess carbohydrates to Spodoptera littoralis and extended Bertrand's rule to macronutrients.
[5] Bertrand was made a member of the Académie Nationale de Médecine in 1931.
In 1932 he became foreign member of the Royal Netherlands Academy of Arts and Sciences.
