• Alcohol is converted into Ethanal in human metabolism.
• Yeast and bacteria convert Ethanal to acetic acid in the vinegar making process.
• Used in the production of wood and bookbinding glues known as polyvinyl acetates
• Vinegar is a very common food in most cultures around the world.
• Ethyl alcohol, found in foods and beverages, must be broken down into Ethanal in our bodies or it would reach a toxic level that would be lethal.
5This is the reaction pathway in our bodies and in vinegar production
• I think food with be less interesting if Ethanal because we wouldn’t have vinegar for our salad dressing, pickles, or countless other recipes that include this sour product.
• Ethanal is a colorless liquid that has a stong “green apple” smell and without it we might not have this flavor for our candy, gum, etc.
• When carbon, hydrogen, and oxygen bind together in Ethanal all of the atoms have full valence shells and benefit in being more stable than existing as atoms alone.
• Since Ethanal reacts with oxygen to form acetic acid, the atoms can be more stable (benefit) when bonded together in acetic acid.
