Adenosine triphosphate (ATP) is an organic compound and hydrotrope that provides energy to drive many processes in living cells.

Euphorbia cyparissias, or Cypress Spurge, is a perennial herb with erect stems, narrow and needle-like leaves, and yellow, crescent-shaped glands on the rim of its cup-shaped flowers. The flowers appear in spring and early summer, consisting of lime-yellow bracts that slowly fade to red-orange as they mature. It spreads by rhizomes and can be quite invasive.
