Ethers are a class of organic compounds that contain an ether
group — an oxygen atom connected to two alkyl or aryl groups — of
general formula R–O–R. A typical example is the solvent and anesthetic
diethyl ether, commonly referred to simply as "ether"
(CH3-CH2-O-CH2-CH3). Ethers are common in organic chemistry and
pervasive in biochemistry, as they are common linkages in carbohydrates
and lignin.
abiather, I am not sure why you would mention ether though without mentioning the essential organic compounds required for life such as proteins, carbohydrates, lipids, and nucleic acids.
Ooooh wait ... that's right. You're taking the Biblical ether here and not the actual organic chemistry one. Sheesh!
Never mind.
