Formic anhydride can be isolated by low-temperature, low-pressure distillation, but decomposes on heating above room temperature. It decomposes into formic acid and carbon monoxide. The decomposition of formic anhydride may be catalyzed by formic acid. Formic anhydride can be detected in the gas-phase reaction of ozone with ethylene. The molecule is planar in the gas phase. Formic anhydride Formic anhydride, also called methanoic anhydride, is an organic compound with the chemical formula and a structural formula of (H(C=O)−)O. It can be viewed as the anhydride of formic acid (HCOOH). Formic anhydride can be obtained by reaction of formyl fluoride with sodium formate
Aromatic-amino-acid transaminase Aromatic-amino-acid transaminase In enzymology, an aromatic-amino-acid transaminase () is an enzyme that catalyzes the chemical reaction Thus, the two substrates of this enzyme are aromatic amino acid and 2-oxoglutarate, whereas its two products are aromatic oxo acid and L-glutamate. This enzyme belongs to the family of transferases, specifically the transaminases, which transfer nitrogenous groups. The systematic name of this enzyme class is aromatic-amino-acid:2-oxoglutarate aminotransferase. Other names in common use include aromatic amino acid aminotransferase, aromatic aminotransferase, and ArAT. This enzyme participates in 6 metabolic pathways: methionine metabolism, tyrosine metabolism, phenylalanine metabolism, phenylalanine, tyrosine and tryptophan biosynthesis, novobiocin biosynthesis, and alkaloid
