“we've done a number of shows that have dealt with fatty acids people probably understand that there are saturated fats, monounsaturated fats, and polyunsaturated fats. The saturated fats have no double bonds so that means every carbon is fully saturated with hydrogen, the monounsaturated have one and only one unsaturation so one double bond and then the polys have at least two of these double bonds.”
