Proteins include structural proteins, enzymes, nucleoproteins, proteins that transport oxygen, muscle protein, and many other types of proteins that have specific functions (Guyton, 1986). Proteins differ from one another in their nutritive value and maybe classified into three groups (Pruthi, 1999): Fats are organic compounds made up of carbon, hydrogen, and oxygen. Fats are the most concentrated source of energy in foods, and they belong to a group of substances called lipids (Food and Nutrition Board, 2005). Dietary fat consists primarily (98 %) of triacylglycerol, which is composed of one glycerol molecule esterified with three fatty acid molecules, and smaller amounts of phospholipids and sterols (Food and Nutrition Board, 2005). Fatty acids are hydrocarbon chains that contain a methyl (CH3-) and a carboxyl (-COOH) end (Food and Nutrition Board, 2005).
