Determination of glutamic oxalacetic transaminase activity by coupling of oxalacetate with diazonium salts.
A method for measuring serum glutamic oxalacetic transaminase activity is described, in which substrate concentrations are more nearly optimal than in previous colonmetric methods. By coupling the diazonium salt at a pH of 4.2, interference from a-oxoglutarate is negligible. Oxalacetate is produced at a linear rate to 180 l.U. Results correlate well with those obtained by a reference spectropho...

متن کاملPhotocatalytic Arylation of Alkenes, Alkynes and Enones with Diazonium Salts
Carbon–carbon bond formation by sp–sp or sp–sp crosscoupling is a key transformation in organic synthesis. Many methods, typically involving transition metal catalysis, are known, and the recent recognition of Richard F. Heck, Ei-ichi Negishi and Akira Suzuki by the Royal Swedish Academy of Sciences (Stockholm, Sweden) when they were awarded the Nobel Prize in Chemistry (2010) underlines the im...
متن کاملCovalent electron transfer chemistry of graphene with diazonium salts.
Graphene is an atomically thin, two-dimensional allotrope of carbon with exceptionally high carrier mobilities, thermal conductivity, and mechanical strength. From a chemist's perspective, graphene can be regarded as a large polycyclic aromatic molecule and as a surface without a bulk contribution. Consequently, chemistries typically performed on organic molecules and surfaces have been used as...
