is it also found in animals?
Yes.
Other animals
n vertebrates, melatonin is produced in darkness, thus usually at night, by the pineal gland, a small endocrine gland
the primary high energy molecule in human metabolism is Adenosine triphosphate (ATP) what is catabolism? It is the set of metabolic processes that breaks down large molecules. which hormones are related to it? Cortisol, glucagon, adrenaline, cytokines, orexin and melatonin. what is the emotional response due to the third one? Fear. how does the first hormone related to metabolism of glucose? Cortisol stimulates the synthesis of 'new' glucose from non-carbohydrate sources; this is known as gluconeogenesis.. is process resisted by insulin? Yes. when was this substance which resists the process discovered? 1921. can it be extracted? Yes. from where? Pancreas. can we find in plants the last hormone in the list of hormones mentioned above? Yes. is it responsible for any memory related disease? No. how does it affect immune system? An antiinflammatory effect seems to be the most relevant.

Introduction Other animals Other animals
In animals (including humans), melatonin is involved in synchronizing the circadian rhythm, including sleep–wake timing, blood pressure regulation, and seasonal reproduction. in seasonal animals. In seasonal breeders that do not have long gestation perio In vertebrates, melatonin is produced in darkness, thus usually at night, by the pineal gland, a small endocrine gland
located in the center of the brain but outside the blood–brain barrier.

Melatonin [SEP] Other animals
In vertebrates, melatonin is produced in darkness, thus usually at night, by the pineal gland, a small endocrine gland located in the center of the brain but outside the blood–brain barrier. Light/dark information reaches the suprachiasmatic nuclei from retinal photosensitive ganglion cells of the eyes rather than the melatonin signal (as was once postulated). Known as "the hormone of darkness", the onset of melatonin at dusk promotes activity in nocturnal (night-active) animals and sleep in diurnal ones including humans. Many animals use the variation in duration of melatonin production each day as a seasonal clock. In animals including humans, the profile of melatonin synthesis and secretion is affected by the variable duration of night in summer as compared to winter.
