[edit] Introduction

Dietary serve a variety of function in the body. One of the most important function is as a metabolic fuel, per gram, fats yield twice as much energy as carbohydrate. All steroid hormones are derived initially from lipid, and these in turn are responsible for the regulation of body functions such as growth, development and the appearance of sexual characteristics as a result of sex hormones. Essential fatty acids, such as linoleic acid and α-linolenic acid are prostaglandin and ecosanoid precursors.
