Il tutto sarebbe riconducibile alla presenza, nell'intestino, di enzimi noti come gamma glutammil-transferasi, che idrolizzerebbero il glutatione assunto per os, riducendone drasticamente la biodisponibilit

Acylcarnitine assay Acylcarnitines were extracted from either 10 l of whole liver homogenate, 50 l of plasma, 50 l brain parenchyma, 50 l cerebrovasculature (timepoint study), 60 l of cerebrovasculature (cerebrovascular uptake study) or 100 l of brain homogenate (all homogenized as described above) and spiked with 5 l of acylcarnitine internal standard (IS) mix containing 12 M TMAO-d9 (Cambridge Isotope Laboratories, Inc., CIL), NSK-B (CIL) and NSK-B-G1 (CIL) at the beginning of the extraction process
Laboratory studies have continued to investigate its role in sleep-wake cycle regulation and its interactions with endogenous sleep-promoting systems
