a neuritogenic compound in human neuroblastoma cells; isolated from Penicillium sp. BM1689-P; structure given in first source
Date introduced: September 26, 1995
Polyenes
Hydrocarbons with more than one double bond. They are a reduced form of POLYYNES.
Year introduced: 1974
Organic Chemicals
A broad class of substances containing carbon and its derivatives. Many of these chemicals will frequently contain hydrogen with or without oxygen, nitrogen, sulfur, phosphorus, and other elements. They exist in either carbon chain or carbon ring form.
Year introduced: 1998
Hydrocarbons, Acyclic
Organic compounds composed exclusively of carbon and hydrogen where no carbon atoms join to form a ring structure.
Hydrocarbons
Organic compounds that primarily contain carbon and hydrogen atoms with the carbon atoms forming a linear or circular structure.
Ethers, Cyclic
Compounds of the general formula R-O-R arranged in a ring or crown formation.
Ethers
Organic compounds having two alkyl or aryl groups bonded to an oxygen atom, as in the formula R1–O–R2.
Epoxy Compounds
Organic compounds that include a cyclic ether with three ring atoms in their structure. They are commonly used as precursors for POLYMERS such as EPOXY RESINS.
Year introduced: 1991(1975)
