Gliadorphin
Gliadorphin
Gliadorphin (pronounced: /gliːəˈdɔːrfɪn/), also known as gluteomorphin, is a bioactive peptide that has opioid activity. It is derived from the incomplete digestion of gliadin, a protein present in gluten.
Etymology
The term "Gliadorphin" is a combination of "gliadin" and "endorphin". "Gliadin" is derived from the Greek word "glia", which means "glue", and "endorphin" is derived from "endogenous morphine", indicating its opioid properties.
Biochemical Role
Gliadorphin is a 7-amino acid peptide that resembles the structure of endorphins, the body's natural painkillers. It is believed to cross the blood-brain barrier and bind to opioid receptors in the brain, causing a range of effects from pain relief to mood alteration.

- Opioid: Any substance that acts on opioid receptors in the brain to produce morphine-like effects. Opioids are most often used medically to relieve pain.
- Peptide: A short chain of amino acids, typically 2-50 in length. Peptides are distinguished from proteins on the basis of size.
