Cycloparaffins. Cyclic Acetylenes . Cyclic Alkenes . Alkenes, Cyclic . Olefins, Cyclic . Cycloalkenes . Cyclic Olefins . Cycloalkanes . Cycloalkynes . Alicyclic hydrocarbons in which three or more of the carbon atoms in each molecule are united in a ring structure and each of the ring carbon atoms is joined to two hydrogen atoms or alkyl groups. The simplest members are cyclopropane (C3H6), cyclobutane (C4H8), cyclohexane (C6H12), and derivatives of these such as methylcyclohexane (C6H11CH3).

Alkenes. Olefins . Pentenes . Unsaturated hydrocarbons of the type Cn-H2n, indicated by the suffix -ene. (Grant & Hackh's Chemical Dictionary, 5th ed, p408) . 0.75
Cyclins. Cyclin . A large family of regulatory proteins that function as accessory subunits to a variety of CYCLIN-DEPENDENT KINASES. They generally function as ENZYME ACTIVATORS that drive the CELL CYCLE through transitions between phases. A subset of cyclins may also function as transcriptional regulators. . 0.60
