A subduction zone is also generated when two oceanic plates collide â the older plate is forced under the younger one â and it leads to the formation of chains of volcanic islands known as island arcs. Examples include the Mariana Islands in the western Pacific Ocean and the Aleutian Islands, off the coast of Alaska.
Gabriel Synthesis. Gabriel Synthesis is an organic chemical reaction in which primary alkyl halides are transformed into primary amines using potassium phthalimide. This reaction is named after a German chemist Siegmund Gabriel.Pure primary aliphatic amines are prepared from alkyl halides by this method.abriel Synthesis.

Phytate. A phytase (myo-inositol hexakisphosphate phosphohydrolase) is any type of phosphatase enzyme that catalyzes the hydrolysis of phytic acid (myo-inositol hexakisphosphate) â an indigestible, organic form of phosphorus that is found in grains and oil seeds â and releases a usable form of inorganic phosphorus.our distinct classes of phytase have been characterized in the literature: histidine acid phosphatases (HAPS), B-propeller phytases, purple acid phosphatases, and most recently, protein tyrosine phosphatase-like phytases (PTP-like phytases).
