Well, it turns out the situation is more complex. I had assumed the answer was what rwst suggests or something to do with osmotic pressure. It seems that we don't really know that well. In a paper from 1991, Chi and Wu suggest the following possible mechanisms : Membrane fusion during the shedding of exovesicles might produce a transient decrease of the ...

There aren't many studies which associate between alcohol consumption and cancer to my knowledge. The association is more with metabolic diseases because the liver is affected. Alcohol is oxidised to acetaldehyde by alcohol dehydrogenase. Acetaldehyde may also, in turn affect the cells by DNA damage if it is not metabolized quickly to acetyl-CoA (perhaps in ...

Ethanol, in less than 50% concentration, emulgates lipids and, through interference with hydrogen bonds, leads to conformational changes in proteins. Higher concentrations lead to denaturation of proteins and osmolysis of cells through small defects, so they finally burst, as ethanol forces a concentration equilibrium. This is why it's a good desinfection ...
