1. carbohydratenoun

   A sugar, starch, or cellulose that is a food source of energy for an animal or plant; a saccharide.

   These microbes are primarily responsible for breaking down cellulose and other carbohydrates into volatile fatty acids (VFAs).

2. Etymology: From their general formula C(HO); they were once thought to be hydrates of carbon.

1. Carbohydrate

   In organic chemistry, a carbohydrate () 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 Cm(H2O)n (where m may or may not be different from n), which does not mean the H has covalent bonds with O (for example with CH2O, H has a covalent bond with C but not with O). However, not all carbohydrates conform to this precise stoichiometric definition (e.g., uronic acids, deoxy-sugars such as fucose), nor are all chemicals that do conform to this definition automatically classified as carbohydrates (e.g. formaldehyde and acetic acid). The term is most common in biochemistry, where it is a synonym of saccharide (from Ancient Greek σάκχαρον (sákkharon) 'sugar'), a group that includes sugars, starch, and cellulose. The saccharides are divided into four chemical groups: monosaccharides, disaccharides, oligosaccharides, and polysaccharides. Monosaccharides and disaccharides, the smallest (lower molecular weight) carbohydrates, are commonly referred to as sugars. While the scientific nomenclature of carbohydrates is complex, the names of the monosaccharides and disaccharides very often end in the suffix -ose, which was originally taken from the word glucose (from Ancient Greek γλεῦκος (gleûkos) 'wine, must'), and is used for almost all sugars, e.g. fructose (fruit sugar), sucrose (cane or beet sugar), ribose, lactose (milk sugar), etc. Carbohydrates perform numerous roles in living organisms. Polysaccharides serve as an energy store (e.g. starch and glycogen) and as structural components (e.g. cellulose in plants and chitin in arthropods). The 5-carbon monosaccharide ribose is an important component of coenzymes (e.g. ATP, FAD and NAD) and the backbone of the genetic molecule known as RNA. The related deoxyribose is a component of DNA. Saccharides and their derivatives include many other important biomolecules that play key roles in the immune system, fertilization, preventing pathogenesis, blood clotting, and development.Carbohydrates are central to nutrition and are found in a wide variety of natural and processed foods. Starch is a polysaccharide and is abundant in cereals (wheat, maize, rice), potatoes, and processed food based on cereal flour, such as bread, pizza or pasta. Sugars appear in human diet mainly as table sugar (sucrose, extracted from sugarcane or sugar beets), lactose (abundant in milk), glucose and fructose, both of which occur naturally in honey, many fruits, and some vegetables. Table sugar, milk, or honey are often added to drinks and many prepared foods such as jam, biscuits and cakes. Cellulose, a polysaccharide found in the cell walls of all plants, is one of the main components of insoluble dietary fiber. Although it is not digestible by humans, cellulose and insoluble dietary fiber generally help maintain a healthy digestive system by facilitating bowel movements. Other polysaccharides contained in dietary fiber include resistant starch and inulin, which feed some bacteria in the microbiota of the large intestine, and are metabolized by these bacteria to yield short-chain fatty acids.

1. carbohydrate

   A carbohydrate is a type of biomolecule mainly composed of carbon, hydrogen, and oxygen atoms, typically with a hydrogen-oxygen atom ratio of 2:1 (the same as in water). They are one of the main types of nutrients and the primary source of energy for many organisms, including humans. Carbohydrates include sugars, starches, and fibers, and they are classified into monosaccharides, disaccharides, oligosaccharides, and polysaccharides based on the number of sugar units they contain.

1. Carbohydratenoun

   one of a group of compounds including the sugars, starches, and gums, which contain six (or some multiple of six) carbon atoms, united with a variable number of hydrogen and oxygen atoms, but with the two latter always in proportion as to form water; as dextrose, C6H12O6

2. Etymology: [Carbon + hydrate.]

1. Carbohydrate

   A carbohydrate is an organic compound that consists only of carbon, hydrogen, and oxygen, usually with a hydrogen:oxygen atom ratio of 2:1; in other words, with the empirical formula Cmn. Some exceptions exist; for example, deoxyribose, a sugar component of DNA, has the empirical formula C5H10O4. Carbohydrates are not technically hydrates of carbon; structurally it is more accurate to view them as polyhydroxy aldehydes and ketones. The term is most common in biochemistry, where it is a synonym of saccharide. The carbohydrates are divided into four chemical groupings: monosaccharides, disaccharides, oligosaccharides, and polysaccharides. In general, the monosaccharides and disaccharides, which are smaller carbohydrates, are commonly referred to as sugars. The word saccharide comes from the Greek word σάκχαρον, meaning "sugar." While the scientific nomenclature of carbohydrates is complex, the names of the monosaccharides and disaccharides very often end in the suffix -ose. For example, grape sugar is the monosaccharide glucose, cane sugar is the disaccharide sucrose, and milk sugar is the disaccharide lactose.

3. Holly Perkins:

4. Patrick McGovern:

   Ancient Brews are very similar people to us, but Ancient Brews don't have the modern tools we do and may have been more in touch with the natural world, if you think about it, if you are only living to 20, you will be looking to your environment for anything that will extend your life, help your diet or cure disease. All these carbohydrate resources and herbs become very important.

5. Frank Hu:

   The No. 1 take-home message for me is that severe restriction of some healthy carbohydrates is not necessary to improve glycemic control and cardio metabolic health, you can do a healthy Mediterranean diet or a moderate low-carbohydrate diet or a very healthy vegetarian diet. There are different options for people with different food preferences.
