BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Melatonin is the hormone released by your brain to make you feel either sleepy at night time or awake during the day. When it’s dark, melatonin is slowly released, telling your body it’s time to go to sleep. Being around too much bright light before bed can affect the level of melatonin that is released.

Detailed explanation-2: -Serotonin (5-hydroxytryptamine) is a small molecule that functions both as a neurotransmitter in the central nervous system and as a hormone in the periphery. Serotonin is synthesized through a multistep pathway in which L-tryptophan is converted into L-5OH-tryptophan by an enzyme called tryptophan hydroxylase (Tph).

Detailed explanation-3: -Melatonin is the only known hormone synthesized by the pineal gland and is released in response to darkness hence the name, “hormone of darkness” [10]. Melatonin provides a circadian and seasonal signal to the organisms in vertebrates.

Detailed explanation-4: -And serotonin is the precursor to melatonin-it gets converted to melatonin in darkness. Melatonin is necessary for regulating our sleep-wake cycle as well as our immune system.

Detailed explanation-5: -Melatonin, released by the pineal gland, controls your sleep patterns. Levels increase at night time, making you feel sleepy.
