JAOCS and Lipids Joint Virtual Issue: Medium Chain Triacylglycerols (MCT)

JAOCS Editor-in-Chief Jim Kenar and Lipids Editor-in-Chief Eric Murphy have teamed up to compile a cross-disciplinary virtual issue featuring papers that focus on MCT-containing oils and their uses.

Visit https://onlinelibrary.wiley.com/page/journal/15589331/homepage/virtualissuemct to read these articles that discuss how MCT oils are used in food products  (JAOCS) and how MCT influence various metabolic pathways in mammals (Lipids).

These articles are open until July 31, 2018.

Medium Chain Triacylglycerols (MCT) 

Triacylglycerols are the main constituents of vegetable oils and fats.  These molecules are esters that are formed between glycerol and three fatty acids.  The majority of vegetable oils, such as soybean oil, are composed of triacylglycerols that contain saturated long chain fatty acids (16-22 carbon atoms), monounsaturated fatty acids, and polyunsaturated fatty acids.   However, some triacylglycerols are predominantly composed of saturated medium chain fatty acids (12-14 carbon atoms) and are designated medium chain triglycerides (MCT). MCT are abundant in palm kernel and coconut oils and, over the last few decades have become considered a source of healthy saturated oils as MCT are readily metabolized for quick energy and have interesting physiological functions.
 
This collection of papers from Lipids and the Journal of the American Oil Chemists’ Society (JAOCS) are focused on MCT containing oils and there uses.  The papers highlighted within JAOCS demonstrate how MCT oils can be blended with other edible oils and modified for use in applications including edible films, confectionary products, margarines and spreads, or structured lipids for infant nutrition.  In contrast, the papers from Lipids demonstrate how MCT influence various metabolic pathways in mammals.  This ranges from the ability of saturated fatty acids to enhance n-3 fatty acid metabolism in animals fed a high fat diet to the role of palmitic acid on cardiomyocyte function.  The positive cardiovascular effect of MCT are detailed in a number of these papers and highlights emerging data demonstrating the mechanisms underlying the positive impact of MCT in human health.
