Saturated and unsaturated fats

Fat or fatty acids are the organic molecules which make up a carbon chain supporting a carboxylic group (R-COOH: the carbon atom linked by a double bond to an oxygen atom and by a single bond to an OH hydroxyl group), at one of its ends and which can consist of one or several double carbon-carbon bonds. If there is no double bond, these acids are called ‘saturated’. If there is a single double bond, they are mono-unsaturated and if there are several double bonds they are poly-unsaturated.
