For all you chemically minded people. How long is the Triglyceride chain in fish oil compared to MCT oil? The reason I am asking is that my wife has a condition that requires here to eat only 10g of dietary fat and supplement the rest with MCT. MMMm good. Her bowel is also inflammed in some areas. So I am wondering how the fish oil would effect the inflammation. But if it is longer than MCT it is going to be absorbed by the gut, vice the stomach, and that is what this whole diet is trying to avoid. It is Lymphangectasia in the bowel.

No idea....too scientific for my brain. I'd google Lymphangectasia and Omega 3 to see what comes up. I would say it is advisable to get some fish oil in there as EFAs can also help repair the gut.

Again not a DR so I would do some research on it.

Medium chain triglycerides (MCT) commonly abbreviated MCT or MCTs, are medium-chain (8 to 12 carbons) fatty acid esters of glycerol.

Unsaturated fatty acids, which includes the Pentaenoic acids (5-double bonds) and hexaenoic acids (six double bonds) have up to 22 Carbon atoms. In other words, they are up to 2x longer than

The physiological relevance is that MCTs passively diffuse through the GI tract(in contrast to all others that are absorbed into the lymphatics and then require modification), they don't require lipase for digestion (most likely why your wife has this RX). These two factors taken together require very little energy expenditure actually a -∆G.

...this is all to say that fish oil would not suffice with this problem because fish oil is absorbed through the lymphatics, is modified before use, and therefore requires more energy to utilize.

I guess palm kernal and coconut oil are the best sources.

MCT's generally hover around 7-10 carbons in length, whereas LCT's are >12. Individual strands of EPA and DHA have 20 and 22 carbons, respectively.
