Adrenaline is a hormone. It is an important neurotransmitter (nerve messenger) and belongs to the catecholamines.

Our body forms it from the amino acids phenylalanine and tyrosine, respectively. Adrenaline increases the tension of the blood vessels and raises blood pressure and heart rate. It has a catabolic effect on sugar metabolism. In addition, adrenaline stimulates the breakdown of triglycerides in fatty tissue.
