So that the reaction is shown on the board. We have carboyl phosphate that reacts with aspartate. So these are the two substrate molecules to the aspartate transcarbomolase and this catalyzes the conversion of these molecules into these two products. We have orthophosphate and we also have the N carbomoyl aspartates. Now the first question you might be thinking is what's the big deal with this reaction? What is the physiological significance of this reaction inside our body?
