Gamma-endorphin is a polypeptide that is characterized by the presence of 17 amino acids, only one more than alpha-endorphin. Similar to other endorphins, research focusing upon gamma-endorphin has been ongoing since its discovery in the 1970s. Yet, most of the information about the substance’s exact role within the body is speculation that has yet to be proven. Some studies have indicated, however, that the polypeptide has antipsychotic effects on a certain category of patients suffering from schizophrenia, while others suggest that gamma-endorphin may act to help regulate blood pressure. Further research is needed, but if gamma-endorphin does indeed possess such characteristics, the substance may eventually be utilized as a highly useful means of medical treatment.
