A common 16-carbon saturated fatty acid that represents 10-20% of the normal human dietary fat intake.

A derivative of thiouracil which has long been used to correct hyperthyroidism; also used as a genetic marker for taste, since only some people detect it as a bitter taste.

A precursor to Vitamin K2 that is capable of both redox cycling and arylating nucleophilic substrates by Michael addition; used as an antihemorrhagic agent and to inhibit the proliferation of various cancer cells.
