WebJul 20, 2024 · RNA nucleotides, unlike the deoxynucleotides of DNA, have a hydroxyl group at the neighboring 2' carbon. The 2' hydroxyl group is right next to the electrophilic phosphorus atom, poised in a good position to make a nucleophilic attack, breaking the RNA chain and forming a cyclic phosphate diester intermediate (see figure below). WebNov 8, 2024 · As the sole member of the head group, the phosphate imparts a -2 charge to the lipid molecule and is referred to as phosphatidic acid (PA). The phosphate moiety exhibits several different levels of protonation, depending on the pH. Below a pH of 4.0, it carries a charge of zero, whereas above pH 12, it is fully deprotonated and with a -2 charge.
