Egg albumin in a vial was heated strongly
WebA series of eight proteins has been studied. There is surprisingly little difference in susceptibility to alcohol denaturation between the various proteins. Methanol, ethanol, propanol, and butanol are strongly bound to egg albumin—butanol being the most strongly bound. The binding of alcohol is probably accompanied by protein dehydration. WebEgg albumin turned black when it was heated strongly in a vial. Moisture can also be observed at the top of the test tube due to the vapors being released. egg albumin …
