Welcome!

We are an encyclopedia project, and more.

We are a different sort of Web 2.0 wiki:

  • We aim at credibility and quality, not just quantity.
  • Both the general public and credentialed experts are encouraged to get involved.
  • We use our real names, not pseudonyms.
  • We're collegial.

We have added over 4,600 articles (and many subpages), and over five million words.

NEW: the Citizendium chooses CC-by-sa as its license!

There are, however, a few very modern, "upscale" bowling alley establishments such as Lucky Strike Lanes where "proper" attire and behaviors are expected. [more...]

Unlike other elements in group VA of the periodic table, phosphorus is never found as a pure element in nature, but only in combination with other elements. It is present in all living organisms in the form of organophosphates and as calcium phosphates such as hydroxyapetite (Ca10(PO4)6(OH)2) and fluoroapatite (Ca10(PO4)6F2), substances found in teeth and bones. Many cell signaling cascades in living organisms operate by a series of phosphorylation events in which a phosphate group (PO4)2− is either added to a protein by a kinase or removed from a protein by a phosphorylase.
