More On Medium Chain Triglyceride Digestion

Posted on April 21, 2014 by Robert Barrington

Medium chain fatty acids are defined as those with chain lengths of between 6 and 12 carbon atoms. Medium chain triglycerides are therefore three fatty acids of this length bonded through an ester bond to a glycerol molecule. Compared to … Continue reading →
