Possible Interaction: Catechin and Glycine

“Rate of absorption of glycine was significantly higher from the glycylglycine solution ( C ) than from the glycine solution (A).”

“Taken together, our data indicated that caffeine and theanine, glycine , or serine in tea might increase the absorption of catechins by the selectively suppressed expression of the efflux transporters induced by catechins.”

“The ability of dog renal cortex slices to accumulate β-methyl-glucoside or glycine is enhanced by the flavonoid (+)-catechin at a concentration of 3.5 mM. This stimulatory effect is apparently due to a decreased rate of efflux of either substrate.”

“The stability and rate … if:1.G and C … glycine , proline (hydroxyproline) and alanine triplets,2.the glycine triplet used were preferentially either GGU or GGA and the proline triplet … alanine triplet did not contain a third base complementary to that used in the opposing glycine or proline triplet.”

“Evidence based on accurate mass analysis of the products obtained and the isotope incorporation pattern …)C-1]glycine, [(13)C-2]glycine, and [(15)N]glycine experiments indicated that (+)-catechin formed various … with glycine ; two of them incorporated a single amino acid, … three adducts incorporated two amino acid moieties.”

“Resistance of spores in glycine crystals to dry heat at 125 C was increased 5 to 24 times compared to unprotected spores.”
