WebBookmark ATP has a high phosphoryl group transfer potential because: A. it exhibits resonance stabilization prior to hydrolysis. B. cleavage of either of its two phosphoanhydride bonds proceeds with a large negative ΔGo' of hydrolysis. C. it has three phosphate groups. D. it is chemically unstable. WebSep 18, 2024 · ATP is composed of an adenine ring, ribose sugar, and three phosphate groups (triphosphate). The groups of the phosphate group are usually called the alpha (α), beta (β), and gamma (γ) phosphates. It is typically related to a monomer of RNA called adenosine nucleotide.
