Chromated copper arsenate - Alchetron, the free social encyclopedia
Chromated copper arsenate (CCA) is a wood preservative that has been used for timber treatment since the mid1930s. It is a mix of chromium, copper and arsenic (as Copper(II) arsenate) formulated as oxides or salts, and is recognizable for the greenish tint it imparts to timber. CCA was invented in

SOLVED: Arsenate Poisoning Arsenate is structurally and chemically similar to inorganic phosphate (P), and many enzymes that require phosphate will also use arsenate. Organic compounds of arsenate are less stable than analogous phosphate compounds, however. For example, acyl arsenates decompose rapidly by hydrolysis: On the other hand, acyl phosphates, such as 1,3 -bisphosphoglycerate, are more stable and undergo further enzymecatalyzed transformation in cells.
