When a neurotransmitter is present in a related amino group, through a carbon pair chain, of an aromatic ring, it is called a monoamine neurotransmitter. For its part, the amino group is functional and derived from ammonia or also one of its derivatives from the alkyl group due to the loss of one of the hydrogen atoms.
Purpose and importance in the body
In another vein, we can say that serotonin is a biomolecule that acts as a neurotransmitter since it sends information between neurons. In people, serotonin is synthesized in neurons of the central nervous system or in cells of the digestive tract. This biomolecule performs a relevant function in the inhibition and regulation of sleep, sexual desire, appetite, anger and body temperature.
This means that different emotional states of the human being, such as anguish, anxiety or fear, are related to the levels of serotonins present in the body.
Depression and serotonin
Depression is one of the ills that can be closely related to serotonin levels, however scientists have not been able to establish exactly without a deficit of the latter that causes it or if, on the contrary, it is the same depression that causes said decrease. One of the existing theories is that this disorder occurs due to hormonal imbalance.
A curious data; it is understood that serotonin levels in the blood can vary; when dusk falls, they rise and stabilize until the beginning of the next day. In addition, men produce 50% higher than women, this explains that they have a high sensitivity to changes in this neurotransmitter in the blood, and which seems to be closely related to postpartum depression and premenstrual syndrome, in the event that the levels are low.
