Isticmaalka
Budada crystalline cad
Cadaan, platelets crystalline ama budo leh ur lagu garto.Hal g wuxuu ku milmaa qiyaastii 30 ml oo biyo ah.Waxay ku milmi kartaa acids-ka iyo xalalka alkali hydroxides.Waa wax yar oo khamriga ku milma, iyo ficil ahaan aan lagu milmi karin etherka.Muuqaal ahaan ma shaqaynayso.pH ee 1 ee 100 xal waa inta u dhaxaysa 5.6 iyo 6.1.Walaxdan waxaa lagu diyaarin karaa in lagu daro methanethiol ilaa acrolein;iyadoo la beddelayo kiimikaad ee methylthiopropionic aldehyde.
d,l-Methionine waxa uu leeyahay ur lagu garto.Waa amino acid lagama maarmaan ah waxaana sidoo kale loo isticmaalaa nafaqeynta iyo kabka cuntada.
Soo saarista xeryahooda kacsan ee la xidhiidha dhadhanka cuntooyinka ka imanaya hoos u dhaca Strecker ee DL-methionine.Ku darida methionine ee xaddi ku habboon cuntooyinkan ayaa laga yaabaa in la filayo inay hagaajiso qiimaha borotiinka.Dhaqaale ahaan, DL-methionine ayaa la door bidi lahaa.Amino acid nonpolar lagama maarmaan ah oo leh sifooyinka difaaca cadaadiska oksaydhative.DL-Methionine waxaa mararka qaarkood la siiyaa kabitaan eeyaha;waxay ka caawisaa eyda inay waxyeeleeyaan cawska iyadoo hoos u dhigaysa pH ee kaadida.
