Accepted Answer

Welcome back, everyone is fructose sex phosphate, a six carbon or three carbon compound. And at which step of glycolysis does it first appear either as a reactant or product? First of all, we want to draw the structure of fructose, starting with a sex member chain. Essentially fructose has a total of six carbon atoms. So 1234, five and six, we have to recall the structure of fructose that where first carbon essentially contains an alcohol group, chtoh, the second one form c Carboni. Then we have carbon with hydroxyl group and hydrogen followed by another carbon that contains hydroxyl group and hydrogen. Then once again, hydroxyl and hydrogen. And this is where we approach carbon number six. Now, overall, we have C h2o h for fructose, but in this case, it is fructose six phosphate. So we essentially have to replace that oh with phosphate as a functional group. So what we're going to do is simply modify that specific carbon into carbon with the original two hydrogens bond it to phosphate oxygen phosphorus. Let's recall that phosphorus contains one double bonded oxygen and the other three oxygens are single bonded. Now, the two oxygen atoms with one bond, they will be negatively charged. And therefore, we have our structure. As we can see, it doesn't differ in terms of the number of carbon atoms from fructose. And we can essentially state that there, there are six carbon atoms. And that's the answer to the first part of the problem. Now, let's recall the three steps of glycolysis. Now, step one in this step, glucose was formulated into glucose, six phosphate. So glucose is phosphorated. Let's call it P into glucose six pate. We have to be very careful. This is not fructose six phosphate. So it's not step one right now, step two, we're going to take our product glucose six phosphate. It is isomerize, let's call it I into fructose six phosphate. This is where we have our product. Now, the third step, we are going to take our product, broke those six phosphate. And now it undergoes phosphorylation. P again, NC broke those 16 buy phosphate. And therefore, we can conclude that first of all, we can see fructose six phosphate as either a reactant or product in step number two, right? Because we are forming it as a product. So the answer to the second part of this problem would be second stop. Let's label it as the final answer to this problem. So basically, we have six carbon atoms in the structure. And the step at which glycolysis, the step of glycolysis at which we first observe fructose six phosphate is the second step. Thank you for watching.
