I'm in my last year of high school and doing a research assignment on thermoregulation. In the excellence level exemplar for the standard, a student made the statement:

Once the body's internal temperature is well above the optimum range, important enzymes start to denature, phospholipids start to destabilise, and cell membrane lipids begin to dissolve. As a result of this, important organs in the trunk of the body are unable to carry out important metabolic processes. If the temperature continues to rise it causes tissue damage which could cause disability depending on its severity. It also causes the hypothalamic thermostat to break down, meaning the body can no longer have control of the core temperature.

However, I have been unable to find any sources which mention destabilisation of phospholipids or the dissolving of membrane lipids. I have also not found anything on tissue damage or the cessation of the hypothalamic thermostat.

Are these things true? And if so, could someone please direct me to a reliable source which states this?
