protein

Researchers from Embrapa (Brazilian Agricultural Research Corporation) and UNB (University of Brasilia) have identified novel peptides in coffee.
These protein fragments have an effect similar to morphine, i.e., analgesic and anxiolytic action, with a positive difference: the duration of these effects was significantly higher.
The identification of the peptides came when the researchers Vinecky Felipe and Carlos Bloch were looking for coffee genes associated with the improvement of product quality.
