Sucrose, a disaccharide, is a sugar composed of glucose and fructose subunits. It is produced naturally in plants and is the main constituent of white sugar. It has the molecular formula C. 12H. 22O. 11 . For human consumption, sucrose is extracted and refined from either sugarcane or sugar beet.
Its molecular formula is C 12 H 22 O 11. [2] White sugars produced from sugar cane and sugar beet are chemically indistinguishable: it is possible, however, to identify its origin through a carbon-13 analysis. [1] White sugar (and some brown sugar) produced from sugar cane may be refined using bone char by a few sugar cane refiners. [3]
Glucose is a sugar with the molecular formula C 6 H 12 O 6. Glucose is overall the most abundant monosaccharide, [ 4] a subcategory of carbohydrates. Glucose is mainly made by plants and most algae during photosynthesis from water and carbon dioxide, using energy from sunlight.
Brown and white granulated sugar are 97% to nearly 100% carbohydrates, respectively, with less than 2% water, and no dietary fiber, protein or fat (table). Brown sugar contains a moderate amount of iron (15% of the Reference Daily Intake in a 100 gram amount, see table), but a typical serving of 4 grams (one teaspoon), would provide 15 calories ...
The ratio of 18 O to 16 O in ice and deep sea cores is temperature dependent, and can be used as a proxy measure for reconstructing climate change. During colder periods of the Earth's history (glacials) such as during the ice ages , 16 O is preferentially evaporated from the colder oceans, leaving the slightly heavier and more sluggish 18 O ...
Water ( H2O) is a polar inorganic compound that is at room temperature a tasteless and odorless liquid, which is nearly colorless apart from an inherent hint of blue. It is by far the most studied chemical compound [ 19] and is described as the "universal solvent " [ 20] and the "solvent of life". [ 21]
Photosynthesis ( / ˌfoʊtəˈsɪnθəsɪs / FOH-tə-SINTH-ə-sis) [ 1] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism.
An example is the condensed molecular/chemical formula for ethanol, which is CH 3 −CH 2 −OH or CH 3 CH 2 OH. However, even a condensed chemical formula is necessarily limited in its ability to show complex bonding relationships between atoms, especially atoms that have bonds to four or more different substituents.
