Message definition (Nutrient)
Macronutrients provide energy:
* [[Carbohydrate]]s are compounds made up of types of [[sugar]]. Carbohydrates are classified according to their number of sugar units: [[monosaccharide]]s (such as [[glucose]] and [[fructose]]), [[disaccharide]]s (such as [[sucrose]] and [[lactose]]), [[oligosaccharide]]s, and [[polysaccharide]]s (such as [[starch]], [[glycogen]], and [[cellulose]]).
* [[Protein]]s are [[organic compound]]s that consist of [[amino acid]]s joined by [[peptide bond]]s. Since the body cannot manufacture some of the amino acids (termed [[essential amino acid]]s), the diet must supply them. Through digestion, [[protein]]s are [[protein catabolism|broken down]] by [[protease]]s back into free amino acids.
* [[Fat]]s consist of a [[glycerin]] molecule with three [[fatty acid]]s attached. Fatty acid molecules contain a -COOH group attached to unbranched [[hydrocarbon]] chains connected by single bonds alone ([[Saturated fat|saturated fatty acids]]) or by both double and single bonds ([[Unsaturated fat|unsaturated fatty acids]]). Fats are needed for construction and maintenance of [[cell membrane]]s, to maintain a stable body temperature, and to sustain the health of skin and hair. Because the body does not manufacture certain fatty acids (termed [[essential fatty acid]]s), they must be obtained through one's diet.
* [[Alcoholic drink|Ethanol]] is not an essential nutrient, but it does provide calories.The [[United States Department of Agriculture]] uses a figure of {{convert|6.93|kcal|lk=in|}} per gram of alcohol ({{convert|5.47|kcal|disp=or|abbr=on}} per [[millilitre|ml]]) for calculating food energy. For [[distilled spirit]]s, a standard serving in the U.S. is {{cvt|1.5|USoz|order=flip}}, which at 40% ethanol (80 [[Alcohol proof|proof]]) would be 14 grams and 98 calories.
