Lycopene isomers
WebBackground: Oral uptake of lycopene has been shown to be beneficial for preventing myocardial ischemia-reperfusion (I/R) injury. However, the strong first-pass metabolism of lycopene influences its bioavailability and impedes its clinic application.

Web1 iun. 1999 · This is in contrast to the lycopene isomer profile reported for biological tissues. Human and animal tissues, including serum, contain significantly more cis-lycopene than the foods where the lycopene originated (Clinton et al. 1996, Stahl and Sies 1992). Human serum contains >50% cis-isomers of lycopene (Schierle et al. 1997, …
Web1 nov. 1992 · The increase in peak serum concentrations was dose-dependent but not linear with the dose. Repeated doses led to a continual rise of lycopene in human serum.
