What is the difference between Phosphate and Phosphorous
https://en.wikipedia.org/wiki/Phosphorus
-
"phosphorus" refers to the element (atomic # 15) specifically. This can be used as reference to an atom of phosphorus in another compound, or as elemental phosphorus (there are a few different ways that P atoms can bond with each other, including diatomic P2 molecules, which are like N2, tetrahedral P4 molecules "white phosphorus," a 1-D polymerized form consisting of vertex-sharing tetrahedra "red phosphorus," 2-D networks "black phosphorus" etc. etc.)
Phosphate refers to a phosphorus atom bound to 4 oxygen atoms. The phosphate anion PO43– is the simplest form, and generally is what is meant by phosphate. But there are also phosphate esters (like trimethyl phosphate, (H3CO)3PO, and different protonation states of phosphate/phosphoric acid, like H3PO4, H2PO4–, and HPO42–.
Depending on the context, "total phosphate" may be used to describe a mixture of different compounds and/or ions containing the PO4 subunit, regardless of what is (or isn't) bound to it. Also, there are polymeric forms of phosphates, like pyrophosphate, and metaphosphate (orthophosphate, in this case is used to specify that monomer).

What is the context of the question?
https://en.wikipedia.org/wiki/Protein_kinase_inhibitor Protein kinases are enzymes that add a phosphate (PO4) group to a protein, and can modulate its function.
I was wondering if any foods contained this ?

The terms phosphorus and phosphate are often used interchangeably when talking about testing, but it is the amount of inorganic phosphate in the blood that is measured with a serum phosphorus/phosphate test. Phosphorus is a mineral that combines with other substances to form organic and inorganic phosphate compounds.
