But you say "methyl" sulphate? What happened to the ethyl moiety? Where did that carbon go?

Oops. Dropped a carbon atom on the floor. It's ethyl sulphate. It turns out that the human body will actually sulphonate ethanol as a means of more rapid excretion via the kidneys. Excretion of ethyl sulphate occurs for hours after the blood levels of ethanol have dropped below detectable limits. It is a sensitive means of detecting whether someone has consumed any ethanol.

I lay blame for loss of the carbon atom on the circulating consequences of a fine bottle of Killian's Red.

Better be glad the carbon didn't go AWOL in the Killian's or you'd be blind.
