Autoregulation is a process within many biological systems, resulting from an internal adaptive mechanism that works to adjust (or mitigate) that system's response to stimuli. While most systems of the body show some degree of autoregulation, it is most clearly observed in the kidney, the heart, and the brain. Perfusion of these organs is essential for life, and through autoregulation the body can divert blood (and thus, oxygen) where it is most needed. 1 Cerebral autoregulation.
Phosphatidylcholine is a ubiquitous, naturally occurring phospholipid molecule. It is the major lipid, or fat, of cell membranes and blood proteins. Also known as PC, phosphatidylcholine serves as the bodyâs main source of choline, an essential nutrient and precursor to the neurotransmitter, acetylcholine. PC is also necessary for the production of surfactants, which are critical for lung function and gastrointestinal health. The terms phosphatidylcholine and lecithin are sometimes used interchangeably; however, lecithin is actually a mixture of several lipids and phospholipids.
