👉 The term "trophonian" is a term used in the field of physiology and biochemistry to describe a protein that has been shown to play a role in regulating blood flow. It's primarily found in certain cells within the circulatory system, such as the heart and brain. The specific function of this trophinin remains unclear, but it is believed to be involved in maintaining homeostasis by modulating the activity of other proteins involved in blood flow regulation.
