Does deamidation of survodutide at 4 °C show up as a loss of content or of purity?

The particulars: deamidation · survodutide · 4 °C.

I understand the observation; what I do not understand is the mechanism behind it.

I have read the two review articles that come up first and both assert this without a citation to a primary source.

What is actually going on here, physically?
