Possible Interaction: Glycine and Polyphenols

“Compared to controls, glycine (18 mM for Shenxuan 1; 9 mM for Lollo Rossa) significantly increased the levels of most antioxidants (including total polyphenols , α-tocopherol) and antioxidant activity, suggesting appropriate glycine supply promotes antioxidant accumulation and activity.”

“Several factors that tend to effect the biodecaffeination during this stage, like moisture, …, intermittent enzyme addition and mixing, were optimized, and inhibitory interactions of proteins with polyphenols , caffeine–polyphenol interactions, which directly influence the biodecaffeination process were prevented by the use of glycine (5% w/w) in the dhool.”

“Proline and arginine are good anchoring points and the glycine gives a certain flexibility in the peptide backbone that allows the polyphenol to approach and interact.”
