1.？ Endorphins are macromolecular peptides secreted by pituitary gland. Endorphins are "bitter before sweet" substances, which are generally produced when people experience pain. People who don't exercise often are more likely to produce. For athletes, they must exceed their limits or exercise more than ordinary people. This is actually a self-protection mechanism of human beings, which can alleviate the pain of self.
Long-term high levels of endorphins are not a good thing for people, because it usually means that your body has experienced great trauma. Fortunately, when people cry, laugh or stretch, they also produce a small amount of endorphins, which is why when we do equipment in the gym, it hurts at that time, but we feel good afterwards.
2.？ Dopamine is a neurotransmitter in the brain, which has a great influence on people's mood. This substance is usually produced when people meet their own needs. According to Dr Loreta Breinin, human ancestors secreted dopamine when they found food or prey after long-term hunger. Dopamine is connected to human neurons, and it will be secreted again when you see those foods or prey again.
3.？ In a word, dopamine is born of happiness and makes people happier; Endorphins are produced by pain and have analgesic effect.

1.？ Significance of dopamine
Dopamine is a neurotransmitter, a chemical used to help cells transmit pulses. This brain secretion is related to people's lust and feelings, and it conveys information of excitement and happiness. In addition, dopamine is also related to various addictive behaviors. Arvid karlsson identified dopamine as the information transmitter in the brain, which won him the 2000 Nobel Prize in Medicine.
20 12, scientists found that dopamine can help to further treat Parkinson's disease. The treatment lies in restoring the level of dopamine in the brain and controlling the disease. German researchers say that dopamine helps to improve memory, and this discovery may help to treat Alzheimer's disease.
2.？ The meaning of endorphin
Endorphin, also known as endorphin or endorphin, is an endogenous morphine-like biochemical compound hormone (secreted by pituitary gland). It is an amino compound (peptide) secreted by the pituitary gland and hypothalamus of vertebrates. It can combine with morphine receptor to produce the same analgesic effect and euphoria as morphine and opioids. Equivalent to natural painkillers. The use of drugs can increase the secretion of endorphins.
English endorphin is a simplified form of endorphin, which has an internal meaning. endo morphine is the English name of morphine, so endorphin means morphine-like substance made by the brain itself. It belongs to pharmacology, not chemical formula.
Endorphins are endogenous peptides produced by the body and have similar effects to morphine. These peptides not only have analgesic function, but also have many other physiological functions, such as regulating body temperature, cardiovascular and respiratory functions. Endorphins are the general term for neuropeptides with morphine-like activity.
