Descrizione generale

The hydrogenation of 1-heptyne with palladium, platinum and ruthenium supported on activated carbon as catalysts, was studied.

Applicazioni

1-Heptyne was used in the synthesis of (6Z,10E,12Z)-octadeca-6,10,12-trienoic acid and (8Z,12E,14Z)-eicosa-8,12,14-trienoic acid.

To study the metabolic fate of conjugated linoleic acid isomers, we synthesized, in seven steps, from 1-heptyne, (6Z,10E,12Z)-octadeca-6,10,12-trienoic acid, (8Z,12E,14Z)-eicosa-8,12,14-trienoic acid, and their [1-(14)C]-analogs.

Palladium, platinum, and ruthenium supported on activated carbon were used as catalysts for the selective hydrogenation of 1-heptyne, a terminal alkyne. All catalysts were characterized by temperature programmed reduction, X-ray diffraction, transmission electron microscopy, and X-ray photoelectron spectroscopy. TPR and

Ammonia monooxygenase (AMO) is a key nitrogen-transforming enzyme belonging to the same copper-dependent membrane monooxygenase family (CuMMO) as the particulate methane monooxygenase (pMMO). The AMO from ammonia-oxidizing archaea (AOA) is very divergent from both the AMO of ammonia-oxidizing bacteria (AOB)

Fermentation broths of Ashbya gossypii from the industrial production of riboflavin emit an intense floral, fruity, and nutty smell. Typical Ehrlich pathway products, such as 2-phenylethan-1-ol and 2-/3-methylbutan-1-ol, were detected in large amounts as well as some intensely smelling saturated
