UI MeSH Term Description Entries
D005030 Ethylenes Derivatives of ethylene, a simple organic gas of biological origin with many industrial and biological use.
D013256 Steroids A group of polycyclic compounds closely related biochemically to TERPENES. They include cholesterol, numerous hormones, precursors of certain vitamins, bile acids, alcohols (STEROLS), and certain natural drugs and poisons. Steroids have a common nucleus, a fused, reduced 17-carbon atom ring system, cyclopentanoperhydrophenanthrene. Most steroids also have two methyl groups and an aliphatic side-chain attached to the nucleus. (From Hawley's Condensed Chemical Dictionary, 11th ed) Steroid,Catatoxic Steroids,Steroids, Catatoxic
