The Favorskii reaction is an organic chemistry reaction between an alkyne and a carbonyl.
HC≡CH + KOH ⇌ HC≡CK + H2O; RR'C=O + HC≡CK ⇌ RR'C(OK)C ≡CH.
Successful reactions with aldehydes often require special solvents to be used, such as DMSO or 1,2-dimethoxyethane with a trace amount of ethanol.
The Wolff-Kishner reduction is a reaction used in organic chemistry to convert carbonyl functionalities into alkanes. In the context of complex molecule synthesis, it is most frequently employed to remove a carbonyl group after it has served its synthetic purpose of activating an intermediate in a preceding step.
For GDP-microtubules, all polymerization and severing reactions were performed at 37°C. Twenty microliters of 100 μM glycerol-free porcine tubulin (Cytoskeleton) was polymerized in 10% DMSO, 1 mM GTP.
