l-adrenaline

Description: L-Adrenaline (L-epinephrine; Adrenalin; Levoepinephrine; Epitrate; Lyophrin; Medihaler-Epi), the levo-isomer of adrenaline, belongs to a group of the compounds known as catecholamines. Epinephrine is a hormone and a neurotransmitter that has many biological functions in the body, regulating heart rate, blood vessel and air passage diameters, and metabolic shifts. Epinephrine release is a crucial component of the fight-or-flight response of the sympathetic nervous system. In chemical terms, epinephrine is one of a group of monoamines called the catecholamines. It is produced in some neurons of the central nervous system, and in the chromaffin cells of the adrenal medulla from the amino acids phenylalanine and tyrosine.
