WebPhosphate esters are ubiquitous in biomolecules and are essential for life, from the sugar phosphates of intermediary metabolism to ATP to phospholipids to the phosphate backbone of DNA and RNA. Some enzymes that form phosphate esters catalyze the formation of arsenate esters. WebThe nucleic acids, such as DNA, RNA, etc., consist of a ribose sugar phosphate backbone, which makes the surface of the molecule highly negatively charged (Fig. 4 ). The intrastrand space in a DNA is occupied by base pairs hydrogen-bonded to each other and forms a hydrophobic domain between the base pairs in the intrastrand region.
