What's the difference between aromatic and cyclic?

Cyclic


Definition:

  • (a.) Alt. of Cyclical

Example Sentences:

  • (3) Cyclic AMP stimulated phosphorylation by [gamma-32P]ATP of two proteins of apparent Mr = 20,000 and 7,000 that were concentrated in sarcoplasmic reticulum, but the stimulation was markedly dependent on the presence of added soluble cyclic AMP-dependent protein kinase.
  • (4) Content of cyclic nucleoside monophosphates was decreased in all the eye tissues in experimental toxico-allergic uveitis as well as penetration of cAMP into the fluid of anterior chamber of the eye.

Forskolin and isoproterenol, which induce cAMP accumulation, activated extractable topoisomerase II (maximum 5-15 min after treatment), but not topoisomerase I. Permeable cyclic nucleotide analogs dBcAMP and 8BrcGMP selectively activated extractable topoisomerase II and topoisomerase I activities, respectively.
