WebApr 28, 2024 · Phosphate, chemical formula PO 43-, is a chemical compound made up of one phosphorus and four oxygen atoms. When it is attached to a molecule containing carbon, it is called a phosphate group. … WebThe 3' carbon of one sugar is bonded to the 5' phosphate of the adjacent sugar. Specifically, the phosphodiester bond links the 3' carbon atom of one sugar molecule and the 5' carbon atom of another (hence the name, 3', 5' phosphodiester linkage). These saccharide groups are derived from deoxyribose in DNA and ribose in RNA.

WebJan 30, 2024 · If you know either pH or pKa, you can solve for the other value using an approximation called the Henderson-Hasselbalch equation: pH = pKa + log ( [conjugate base]/ [weak acid]) pH = pka+log ( [A - ]/ [HA]) pH is the sum of the pKa value and the log of the concentration of the conjugate base divided by the concentration of the weak acid. russell crossman coventry ri
