Naturally Occurring Organosulfur Compounds
Not all organosulfur compounds are foul-smelling pollutants. Penicillin and cephalosporin are life-saving antibiotics, derived from fungi. Gliotoxin is a sulfur-containing mycotoxin produced by several species of fungi under investigation as an antiviral agent. Compounds like allicin and ajoene are responsible for the odor of garlic, and lenthionine contributes to the flavor of shiitake mushrooms. Volatile organosulfur compounds also contribute subtle flavor characteristics to wine, nuts, cheddar cheese, chocolate, coffee, and tropical fruit flavors. Many of these natural products also have important medicinal properties such as preventing platelet aggregation or fighting cancer.

Famous quotes containing the words naturally and/or compounds:
“Glorious bouquets and storms of applause ... are the trimmings which every artist naturally enjoys. But to move an audience in such a role, to hear in the applause that unmistakable note which breaks through good theatre manners and comes from the heart, is to feel that you have won through to life itself. Such pleasure does not vanish with the fall of the curtain, but becomes part of one’s own life.”
—Dame Alice Markova (b. 1910)
“We can come up with a working definition of life, which is what we did for the Viking mission to Mars. We said we could think in terms of a large molecule made up of carbon compounds that can replicate, or make copies of itself, and metabolize food and energy. So that’s the thought: macrocolecule, metabolism, replication.”
—Cyril Ponnamperuma (b. 1923)
