Phosphonates are one of the three sources of phosphate intake in biological cells. [ citation needed ] The other two are inorganic phosphate and organophosphates. The naturally occurring phosphonate 2-aminoethylphosphonic acid was first identified in 1959 in plants and many animals, where it is localized in membranes.
Phosphonates are esters of phosphonic acid and have the general formula RP(=O)(OR') 2. Phosphonates have many technical applications, a well-known member being glyphosate, better known as Roundup. With the formula (HO) 2 P(O)CH 2 NHCH 2 CO 2 H, this derivative of glycine is one of the most widely used herbicides.
In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid, a.k.a. phosphoric acid H 3 PO 4. The phosphate or orthophosphate ion [PO 4] 3− is derived from phosphoric acid by the removal of three protons H +.
Phosphates have low toxicity in the environment but cause nutrient pollution, a major water quality problem in many watersheds. [17] Phosphates in water cause eutrophication of algae which creates conditions favorable to formation of harmful algal blooms. These blooms prevent light and oxygen from getting into the water, leading to the death of ...
Oxidation of phosphonites gives phosphonates: 2 P(OR) 2 R + O 2 → 2 OP(OR) 2 R. Phosphonites can function as ligands in homogeneous catalysis. [3] References

The term phosphate is also used in organic chemistry for the functional groups that result when one or more of the hydrogens are replaced by bonds to other groups. These acids, together with their salts and esters , include some of the best-known compounds of phosphorus, of high importance in biochemistry , mineralogy , agriculture , pharmacy ...
I tend to buy the 2-liter bottles, and last time I shopped, they clocked in at $21.99 for avocado and $26.39 for extra-virgin olive oils—both of which were about half the price that I would've ...
