So in that particular case, this is basically what we produce. And this is a much more common type of phospholipid, more specifically phosphlyceride that will find in the cell membrane. So notice here we have a bond that is formed between this phosphate, this phosphorus atom of the phosphate group, and this oxygen of this choline. So we can basically replace this with a serene in which there will be a bond between this phosphorus atom and this oxygen. Or we can remove this and basically attach this phosphorus atom to this oxygen here. Either case, we basically form a modified version of this molecule here.
