> As I've shown, you can mostly restate a technical paragraph with two plain English sentences.
You've taken a paragraph that contained a lot of details and was quite precise, and replaced it with wishy washy language. For example, they day that the cells they found are heterodimers of the T1R cells on your tongue, specifically T1R2/3. You replaced this precise explanation with the single word "similar", which could mean that they are enitrely different cells that are tautologically "similar" in also detecting sweet tastes.
They were also explaining exactly what the cells detect, which you thought is not worthy of mention.
The single short clear phrase "upper GI tract" you replaced with the longer and more akward "the part of the GI tract between the mouth and the duodenum".
Overall, your phrase would sound more complex and awkward to a practitioner, and you have reduced the information significantly. There is a reason technical language is used in technical papers - it allows you to be concise, information dense, and precise.
