Food Preservatives Radical inhibitors found in food are known as preservatives. They preserve food by preventing radical chain reactions. Vitamin E is a naturally occurring preservative found in such things as vegetable oil, sunflower seeds, and spinach. BHA and BHT are synthetic preser- vatives that are added to many packaged foods. Notice that, like hydroquinone, vitamin E and all the synthetic preservatives are phenols. OH C(CH) он он CCH,), (CH,,C.

Paroxetine (Paxil) is an antidepressant that is a member of a family of drugs known as Selective Serotonin Reuptake Inhibitors (SSRIS). This family of drugs also includes fluoxetine (Prozac) and sertraline (Zoloft). SSRIS work by inhibiting the reuptake of the neurotransmitter serotonin in the synapses of the central nervous system follow- ing release of serotonin during excitation of individual nerve cells. Between firings, the serotonin is taken back up by a nerve cell in preparation for firing again. Inhibition of reuptake has the effect of increasing the time serotonin molecules remain in the syn- apses following excitation, leading to a therapeutic effect. In one synthesis of parox- etine, the following reagents are used. Draw the structures of synthetic intermediates A and B. F НО SOCI, A B HO Pyridine

When trichloroacetaldehyde is dissolved in water, almost all of it is converted to the hydrate. Chloral hydrate, the product of the reaction, is a sedative that can be lethal. A cocktail laced with it is known—in detective novels,at least—as a “Mickey Finn.” Explain why an aqueous solution of trichloroacetaldehyde is almost all hydrate.
The analgesic Tylenol is often taken by people who are allergic to aspirin. Tylenol contains acetaminophen (structure shown) as the active ingredient. Is the structure of acetaminophen similar to the structure of aspirin? In what way? Would acetaminophen give a positive phenol test? What products would be obtained if acetaminophen were hydrolyzed in acidic aqueous solution?

4) Multistriatin, one of the pheremones of the elm bark beetle, is a volatile compound released by a virgin female beetle when she has found a good food source - an elm tree. Male beetles, which carry the Dutch elm disease fungus, are attracted by the pheromone; the tree becomes infected with the fungus and soon dies. Multistriatin is used to trap the beetles, but the amount in beetles is so miniscule that the compound must be synthesized. The following synthesis of multistriatin uses only chemistry that we have seen in Chem 348. HO. НО Br type O type.

In the mid-1930s a substance was isolated from a fungus that is a parasite of ryes and other grasses. This alkaloid, lysergic acid, has been of great interest to chemists because of its strange, dramatic action on the human mind. Many derivatives of lysergic acid are known, some with medicinal applications. Perhaps the best known derivative of lysergic acid is the potent hallucinogen lysergic acid diethylamide (LSD): మగవా జి N-H LSD (CH25N;O) Like other alkaloids, LSD is a weak base, with Kp = 7.6 × 107.

Amidation Reactions Part A Learning Goal: To identify characteristics common to all amidation reactions, and to apply these generalities in drawing specific amidation reactants or products. Part B Amidation reactions are condensation reactions. In a condensation reaction, two molecules join with a new covalent bond, and this results from the removal of a small molecule such as a water molecule. The reactants in amidation are a carboxylic acid and an amine, and the products are an amide and a water molecule. The carboxylic acid reactant can be of any type. The amine can be simple ammonia (NH₂). a primary amine. or a secondary amine. It cannot be a tertiary amine because tertiary amines lack the N-H Aspartame, an amide, is the sweetener commonly used in diet cola.
