    en.wikipedia.org/wiki/Category:Carbohydrates

    Carbohydrates (literally hydrates of carbon) are chemical compounds, which together with proteins, lipids , and nucleic acids (RNA/DNA), constitute the 4 principal biological macromolecules of which all life on Earth is composed. Together with lipids, carbohydrates are the primary means by which living organisms store energy.

    Lactose is a disaccharide found in animal milk. It consists of a molecule of D-galactose and a molecule of D-glucose bonded by beta-1-4 glycosidic linkage.. A carbohydrate (/ ˌ k ɑːr b oʊ ˈ h aɪ d r eɪ t /) is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen–oxygen atom ratio of 2:1 (as in water) and thus with the empirical formula C m ...

    MyPyramid was often displayed with the food images absent, creating a more abstract design. In an effort to restructure food nutrition guidelines, the USDA rolled out its new MyPlate program in June 2011. My Plate is divided into four slightly different sized quadrants, with fruits and vegetables taking up half the space, and grains and protein ...
