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 ...
Food is any substance consumed to provide nutritional support and energy to an organism. [2] [3] It can be raw, processed, or formulated and is consumed orally by animals for growth, health, or pleasure. Food is mainly composed of water, lipids, proteins, and carbohydrates.
This happens whenever the molecular graph is symmetrical, as in the 3-ketopentoses H(CHOH) 2 (CO)(CHOH) 2 H, and the two halves are mirror images of each other. In that case, mirroring is equivalent to a half-turn rotation. For this reason, there are only three distinct 3-ketopentose stereoisomers, even though the molecule has two chiral carbons.
In the diet-crazed world that we live in, any food that is can be categorized as a carbohydrate gets a bad rap despite the fact that carbs are necessary for a healthy diet. (Good luck eating ...
[2] [3] Natural saccharides are generally composed of simple carbohydrates called monosaccharides with general formula (CH 2 O) n where n is three or more. Examples of monosaccharides are glucose, fructose, and glyceraldehyde. [4] Polysaccharides, meanwhile, have a general formula of C x (H 2 O) y where x and y are usually large numbers between ...
Fat has a food energy content of 38 kilojoules per gram (9 kilocalories per gram) proteins and carbohydrates 17 kJ/g (4 kcal/g). [2] Water makes up a large proportion of the total mass ingested as part of a normal diet but it does not provide any nutritional value.
Dextrin [1] – an incompletely hydrolyzed starch made from a variety of grains or other starchy foods. Dextrose [1] – same as glucose, dextrose is an alternative name of glucose; Disaccharide – also known as double sugar, it is made when two monosaccharides (aka simple sugars) are joined together. Examples include sucrose, lactose, and ...
Fast food gets a bad rap for being unhealthy, but there are healthy fast food options at chains like McDonald’s, Pizza Hut, and Sonic. ... for example, while others may have to pay closer ...
