2 NUTRIENTS elements or compounds necessary for an organism's metabolism, growth, or other functioning. elements or compounds necessary for an organism's metabolism, growth, or other functioning. some of them are essential,because they cannot be synthesized in the body and must be obtained from a food source. some of them are essential,because they cannot be synthesized in the body and must be obtained from a food source. substances that provide energy substances that provide energy nutrients:živiny

3 Groups of nutrients Carbohydrates Carbohydrates Proteins Proteins Fats Fats Minerals Minerals Fat-soluble vitamins Fat-soluble vitamins Water-soluble vitamins Water-soluble vitamins Water Water

4 Carbohydrates compounds made up of sugars used or stored as energy compounds made up of sugars used or stored as energy have three different types of simple sugars:1) monosaccharide have three different types of simple sugars:1) monosaccharide 2) disaccharide 2) disaccharide 3) polysaccharide 3) polysaccharide Complex carbohydrates are stored in the body as glycogen.
