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 ...
Carbohydrate metabolism is the whole of the biochemical processes responsible for the metabolic formation, breakdown, and interconversion of carbohydrates in living organisms. Carbohydrates are central to many essential metabolic pathways . [ 1 ]
[6] [7] [8] Soluble fibre is marketed as serving a prebiotic function with claims for promoting "healthy" intestinal bacteria. [9] Bacterial metabolism of soluble fibre also produces short-chain fatty acids like butyric acid which may be absorbed into intestinal cells as a source of food energy. [6] [7] [8] cellulose; methyl cellulose ...
Two of the main functions of carbohydrates are energy storage and providing structure. One of the common sugars known as glucose is a carbohydrate, but not all carbohydrates are sugars. There are more carbohydrates on Earth than any other known type of biomolecule; they are used to store energy and genetic information , as well as play ...
The main fuel used by the body during exercise is carbohydrates, which is stored in muscle as glycogen – a form of sugar. During exercise, muscle glycogen reserves can be used up, especially when activities last longer than 90 min. [ 161 ]

Through digestion, dietary carbohydrates are broken down and converted into glucose, which is the sole energy source for the brain. [5] [8] [11] Optimal brain function relies on adequate carbohydrate consumption, as carbohydrates provide the quickest source of glucose for the brain. [12]
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.
