Okay, I'm a biochem geek. I've spent probably an hour looking up information on C12 metabolism and found something interesting - I CAN'T FIND A THING. Slightly more than half the sources I read classify C12 as an MCFA, and slightly less classify it as a LCFA. However, more "reputable" sources (educational, etc.) tend to classifcy it as an LCFA, but this proves nothing. I couldn't find a thing about whether it was hydrolysed in vivo or not.
In one Japenese study they refer to a C12 FA as being hydrolysed by a certain enzyme. That's the closest I have. :o\ Sketchysketchy.
