Peer review -- HelinaSaleh:

I thought the information flowed well generally.Your sentences were concise and easy to follow
Just to clarify, in this sentence: The structure of β-endorphin in part accounts for this through its resistance to proteolytic enzymes☂. By "this" did you mean beta -endorphin's high affinity and long lasting effects on opioid receptors. If so, I would suggest using this high affinity instead of the word this by itself to avoid confusion to what you're referring to.
I would link the word Neuropeptide to be on the safe side.
" Evidence suggests " maybe instead put Recent studies suggest or There has been evidence found that shows ....
β-Endorphin function is said to be divided into two main categories: local function and global function. Maybe instead of using "is said to be divided" use . β-Endorphin's function consists of two main categories .
In the peripheral nervous system, β-endorphin binds the μ-opioid receptor, directly inhibiting the release of substance P. In the central nervous system, β-endorphin is released through the periaqueductal grey network in response to this signal and mainly acts to inhibit the release of GABA, a neurotransmitter which prevents the release of dopamine. Thus, the inhibition of GABA release by β-endorphin allows for a greater release of dopamine. This twofold approach reduces pain sensation, allowing for the body stop a pain impulse once it has been sent. * for this part I would suggest to first indicate that β-Endorphin inhibits pain signals in two ways ( peripheral and central nervous system) and then go on to explain how β-Endorphin accomplishes these tasks.
