Chemical structure of<unk> s<unk> s are a very large family of chemically related mycotoxins produced by various species of Fusarium, Myrothecium, Trichoderma, Trichothecium, Cephalosporium, Verticimonosporium, and Stachybotrys.<unk> s are a class of sesquiterpenes. The most important structural features causing the biological activities of<unk> s are the 12,13-epoxy ring, the presence of hydroxyl or acetyl groups at appropriate positions on the<unk>  nucleus, and the structure and position of the side-chain. They are produced on many different grains like wheat, oats or maize by various Fusarium species such as F. graminearum, F. sporotrichioides, F. poae and F. equiseti. Some molds that produce<unk>  mycotoxins, such as Stachybotrys chartarum, can grow in damp indoor environments. It has been found that macrocyclic<unk> s produced by S. chartarum can become airborne and thus contribute to health problems among building occupants. A poisonous mushroom in Japan and China, Podostroma cornu-damae, contains six<unk> s, including satratoxin H, roridin E, and verrucarin.
