Lenthionine is an organosulfur compound with the formula (CH₂)₂S₅. The compound consists of a 1,4-C₂S₅ ring (pentathiepane). Lenthionine is a major component of the organosulfur compounds found in shiitake mushrooms (Lentinula edodes). onions, and garlic, and it is partly responsible for their flavor. The mechanism of its formation is unclear, but it likely involves the enzyme C–S lyase.
