combine together to make the glue active. When we cut onion we start the chain of reactions allowing the Allilin to come in contact with Allilinase to turn the Allilin into Sulfenic Acid and this Sulfenic Acid turns into syn-Propanethial-S-oxide though the enzyme Lachrymatory Factor Synthase...
(called"patients"in the following parts of the passage) often had more chemical reactions (化学反应) in their brains.The researchers thought lowering the temperature of the head might help.On the first two nights of testing,the patients wore no water caps.During the next two nights,the caps ...
UV/Vis spectroscopy is a powerful tool in analytics. It uses the ultraviolet and visible light spectrum to measure the absorption of molecules, providing insights into their structure and concentration. Whether determining protein concentrations, characterizing compounds or monitoring chemical reactions, UV...
