Bioquímica e ação citotóxica de alfa-aminocetonas endógenas Biochemistry and cytotoxicity of alpha-aminoketones

Química Nova, 2005
alpha-Aminoketones are expected to undergo enolization and subsequent aerobic oxidation yielding oxyradicals and highly toxic a-oxoaldehydes. Our interest has been focused on two endogenous a-aminoketones: 5-aminolevulinic acid (ALA) and aminoacetone (AA)
