Dear Juan,

Adsorption of fat soluble vitamins should not be affected, as apoB48 is derived from apoB transcripts that are RNA-edited in exon 26. Any transcript longer than the RNA-editing point will therefore result in functional apoB48.

For the answer to your other question, please have a look at these papers:
