Rubiscolin

The rubiscolins are a group of opioid peptides that are formed during digestion of the ribulose bisphosphate carboxylase/oxygenase (Rubisco) protein from spinach leaves. Rubiscolins mimic the effects of opiates and, therefore, influence the brain. These peptides have much in common with the better-known gluten exorphins.

There are 2 known rubiscolins with known structure:

Rubiscolin-5

Rubiscolin-6

• Structure: H-Gly-Tyr-Tyr-Pro-Thr-OH
• Chemical formula: C₃₉H₅₄N₆O₁₀
• Molecular weight: 766.87 g/mol
