    Article Title: In vitro digestion, cellular uptake and absorption of walnut protein-based nanoparticles mediated coenzyme Q10 nanosuspensions
    Article Snippet: Oral administration of Coenzyme Q10 (CoQ10) is hindered by its low bioaccessibility, and protein-based nanoparticles, commonly used to improve this, are vulnerable to degradation by pH, salts, and enzymes.. This study examined the in vitro digestion behavior and the subsequent cellular uptake and absorption of walnut protein-based nanoparticle-stabilized CoQ10 nanosuspensions (CQ@WPNP) to investigate their potential utility in addressing these challenges.. Cryo-electron microscopy (Cryo-EM), revealed structural rearrangements of CQ@WPNP during digestion, with both WPNP and CoQ10 nanoparticles remaining stable in the gastric phase, thereby preventing premature release.
