Lycopene isomerisation takes place within enterocytes during absorption in human subjects

Lycopene isomerisation takes place within enterocytes during absorption in human subjects.

Lycopene in fruits and vegetables occurs mostly (80-97 %) in the all-E configuration, whereas a considerable proportion of lycopene in the human body is present as Z-isomers. The Z-isomers offer potentially better health benefits and show improved antioxidant activity in vitro when compared with the all-E-isomer. The absorption of dietary lycopene is a complex process involving transfer of the ...

Isomerisation and degradation of lycopene during heat processing in simulated food system

The degradation and/or isomerisation of lycopene have an important influence on its bioavailability and bioactivities. Existing studies have shown that the configuration profiles and stability of lycopene will be changed because of heat processing, but the relationship between the structure conversion of lycopene and the intensity of heat treatment is yet to be further studied. To simplify the ...

Posttranslational N-glycosylation takes place during the normal processing of human coagulation factor VII.

N-glycosylation is normally a cotranslational process that occurs during translocation of the nascent protein to the endoplasmic reticulum. In the present study, however, we demonstrate posttranslational N-glycosylation of recombinant human coagulation factor VII (FVII) in CHO-K1 and 293A cells. Human FVII has two N-glycosylation sites (N145 and N322). Pulse-chase labeled intracellular FVII mig...
