there are some spelling errors in the video, sorry about that.

Here are some memory trick to help you:
1) Erythose4P and Ribose5P both have "r" in them, this reminds me that OH in these molecules point to the right
2) transketolase always forms Glyceraldehyde3P but transaldolase doesnt
3) Sedoheptulose7P is just an extended version of Fructose6P
4) The length of the sugars corresponds to the C # at which the phosphate (P) is attached (not true of all pathways, but in this one it is)
