beta-carotene is converted primarily to retinoids in rats in vivo.
Barua AB, Olson JA. Barua AB, et al. J Nutr. 2000 Aug;130(8):1996-2001. doi: 10.1093/jn/130.8.1996. J Nutr. 2000. PMID: 10917914
Another beta-carotene derivative, with a spectrum similar to that of semi-beta-carotenone, citranaxanthin and beta-apo-6'-carotenal, was also found in the intestinal extract of a -A rat. beta-Apocarotenals, beta-apocarotenols, beta-apocarotenyl esters and bet …

Carotenoid composition and its chemotaxonomic significance in leaves of ten species of the genus Ceratozamia (Cycads).
Cardinif F, Bonzi LM. Cardinif F, et al. J Plant Physiol. 2005 May;162(5):517-28. doi: 10.1016/j.jplph.2004.06.007. J Plant Physiol. 2005. PMID: 15940869
It is constituted of three very rare keto-carotenoids, which were, in our case, identified for the first time from the photosynthetic tissues (semi-beta-carotenone, triphasiaxanthin, and beta-carotenone). It is also constituted of four others, which are compl …

Quantitative variations of individual carotenoids in relationship with the leaflet development of six species of the genus Ceratozamia (Cycads).
Cardini F, Pucci S, Calamassi R. Cardini F, et al. J Plant Physiol. 2006 Feb;163(2):128-40. doi: 10.1016/j.jplph.2005.05.012. Epub 2005 Aug 31. J Plant Physiol. 2006. PMID: 16399003
As no official A1cm1% coefficients were available, it was necessary to calculate these for the following stroma carotenoids: semi-beta-carotenone (major component), triphasiaxanthin, ceratoxanthin, ceratozamiaxanthin, kuesteriaxanthin and ceratoxanthone. ...
