What is the significance of phosphoric anhydride linkages in ATP and how does this relate to metablism

Back 40

The phosphoanhydride linkages are very high energy bonds, because they have no resonance. they are so important in metabolism because when you break their bonds, a lot of energy is released

Front 41

what are thioester bonds and they are they important in metabolism?

Back 41

This bond forms when a thiol joins a COOH. It is important because it is a high energy bond, releases energy and is required for the formation of acetyl CoA. Panthothenic acid builds CoA, this is why it is important to have this in your diet
