The above focuses on some chemicals and elements in the human body that affect emotional and mental health. 1 phenylethylamine This substance is easily soluble in water, alcohol and ether, colorless and strongly alkaline liquid, with fishy smell. In vivo, phenylalanine is decarboxylated in the brain, which can induce the generation of catecholamine receptors and has antidepressant effect, and is further oxidized to phenylethanolamine. When people's mood changes, phenylethylamine will be secreted from the bottom of the brain, which is called "sex hormone" by superstitious people. Chocolate, especially dark chocolate, is rich in content? . Endorphin is a primary biological endogenous opioid similar to morphine. Endorphin is the rarest kind of endorphin secreted by pituitary gland, which contains amino acid residues of l6, 17, 3 1. The structure is similar, but the C-terminal is different. Endorphin, also known as endorphin or endorphin, is an endogenous morphine-like biochemical decomposition hormone secreted by pituitary gland. It is an amino compound (peptide) secreted by pituitary gland and hypothalamus of vertebrate plants. It can bind to morphine receptor and has the same effect as morphine and opioids.

It is an adrenocortical hormone extracted from the adrenal cortex and has the strongest effect on glucose metabolism. Under stress, the body needs cortisol to maintain its physiological function. Without it, the body can't respond ineffectively to stress. This is because cortisol secretion can release amino acids in muscle, glucose in liver and fatty acids in adipose tissue, which are sent to the blood for energy use.
