In organic chemistry, an "enamine" is the rearrangement product of an imine, itself the reaction product of a carbonyl compound — an aldehyde or ketone — with either ammonia or an amine — primary or secondary. Derivation of the term is from the words "alkene" and "amine" — the two ...
Grilled Red Meat: While grilled food can taste delicious, scientists have discovered that preparing meats in this way – especially processed meats like hot dogs – releases a carcinogen called heterocyclic aromatic amines. When you grill red meat to the point of well-done, it changes the chemica...
