Ep 27 - Fruit Mash, Grain Mashes, Cyanogenic glycosides, Glycosidic nitriles, and Ethyl carbamate
Hello All,
Time for another video to drop. This one is on Fruit mashes, Grain mashes, Cyanogenic glycosides, Glycosidic nitriles, and Ethyl carbamate.
I hope you like it.
Have a great week!
Note: I screwed up the settings in the camera and recorded in Cinema 4k, which is 4096x2160, instead of 4k UHD which is 3840x2160, which is why there are black bars present.

Amino Acid Leucine -- CYP79 +O2 +NADPH -- right-handed aldoxime
right-handed aldoxime -- CYP71 (flips hydroxyl) -- left-handed aldoxime
left-handed aldoxime -- CYP71 +NADPH +hydroxyl -- nitrile
nitrile -- CYP71 + O2 + NADPH -- hydroxynitrile
hydroxynitrile -- UDP glucuronosyltransferase -- Epiheterodendrin (Acrospires of malted barley)
Epiheterodendrin -- yeast beta-glucosidase -- Isobutyraldehyde cyanohydrin
Isobutyraldehyde cyanohydrin -- Thermal decomposition -- Isobutyraldehyde + HCN
HCN + H2O + O2 + heat --- ethyl carbamate
