WebDec 30, 2024 · To incorporate phosphate into biomolecules, prebiotic experiments commonly use molar phosphate concentrations to overcome phosphate’s poor reactivity with organics in water. However, phosphate is generally limited to micromolar levels in the environment because it precipitates with calcium as low-solubility apatite minerals. WebPhosphorus (P) is a multi-valent nonmetal chemical element of the VA group, No 15 of the Periodic System. Its molar mass is 30.97. Twenty-three isotopes of phosphorus are known, but only one of them is stable. …
