The name carbohydrate is used to designate the large class of compounds that are ploy-hydroxy aldehydes or ketones, or substances that yield such compounds upon acid hydrolysis. In plants, energy from the Sun is used to convert carbon dioxide and water into the carbohydrate glucose. Carbohydrates are biological molecules made of carbon, hydrogen, and oxygen in a ratio of roughly one carbon atom () to one water molecule ( ). 1. A carbohydrate is either a sugar or a polymer of sugars. 87 -23.7 Carbohydrate component of nucleic acids and coenzymes. A polymer is two or more simple sugars joined together. Some of the most common carbohydrates that we come across in our daily lives are in form of sugars. Polysaccharides are chains of many sugar subunits. Many of the hormones are proteins. The simplest carbohydrates also contain either an aldehyde moiety (these are termed polyhydroxyaldehydes) or a ketone moiety ( polyhydroxyketones ).

The substance most people refer to as "sugar" is the sucrose disaccharide, which is extracted either from sugar cane or beets. iv. Carbohydrates are carbon compounds that contain large quantities of hydroxyl groups. The digestive . Biochemists study large molecules such as carbohydrates and proteins in relation to metabolism and other important processes within the body. Carbohydrates are formed by green plants from carbon dioxide and water during the process of photosynthesis. Carbohydrates 1. Enzymes are made up of proteins. 160 + 105 Free in heartwood of coniferous trees; widely distributed in combined form as glycosides and polysaccharides. So 'carbo', for carbon, and 'hydrate', for hydration or water. They are classified into monosaccharides, oligosaccharides, and polysaccharides. "ose" = sugar. Carbohydrates are the most abundant of all the organic compounds in nature. long sugar chains for glucose storage. (b) Glycolipids, which yield fatty acids, sphingosine or glycerol, and a carbohydrate upon hydrolysis. More rigorous and a accurate definition would be Polyhydroxy Aldehydes and Ketones composed of Carbon, Hydrogen and Oxygen. Carbohydrates are literally "hydrates of carbon.". 145 +18.8 Called wood sugar because it is widely general formula for carbohydrates. Biological Importance of Proteins: i. Proteins are the essence of life processes. (a) Phospholipids, which yield fatty acids, glycerol, phosphoric acid and a nitrogen-containing alcohol upon hydrolysis. Definition of carbohydrate : any of various neutral compounds of carbon, hydrogen, and oxygen (such as sugars, starches, and celluloses) most of which are formed by green plants and which constitute a major class of animal foods Example Sentences Phrases Containing carbohydrate Learn More About carbohydrate Examples of carbohydrate in a Sentence definition- polyhydroxy aldehydes or ketones or compounds which produce them on hydrolysis monosaccharides- simple sugar unit, can't be hydrolyzed further further classified on the basis of. Definition of biochemistry: Biochemistry is the branch of science that explores the chemical processes within and related to Carbohydrates serve as energy sources and as essential structural components in organisms; in addition, part of the structure of nucleic acids, which contain genetic information, consists of carbohydrate. Carbohydrates are one of the three macronutrients in the human diet, along with protein and fat. Monosaccharides can bond together to form disaccharides and polysaccharides. Since hydrogen and oxygen are present in the same proportions as in water, it was believed that this group of compounds could be chemically described as hydrates of carbon. Biochemistry Definition. 2. Carbohydrates definition at Dictionary.com, a free online dictionary with pronunciation, synonyms and translation. spatial arrangement of atoms or groups around a chiral molecule. They are the most abundant organic molecules in nature and are also referred to as "saccharides". ii. Familial combined hyperlipidemia: An autosomal dominant disorder, characterized by the excessive synthesis of lipoproteins containing apolipoprotein B.

Sugars also are added to foods during processing and preparation or at the . Each day . Mono and disaccharides are sometimes referred to as simple sugars. Carbohydrates are subdivided into several categories on the basis of the number of sugar units and how the sugar units are chemically bonded to each other. Carbohydrates are essential nutrients which include sugars, fibers and starches. Categories include sugars, starches, and fibers. depending on the number of carbon atoms in the molecule. This composition gives carbohydrates their name: they are made up of carbon ( carbo -) plus water (- hydrate ). About 65% of the foods in our diet consist of carbohydrates. The definition of carbohydrates as compounds containing C, H and O usually with the empirical formula C m ( H 2 O) n, is outdated. Biochemistry, or biological chemistry, is the branch of science that studies chemical and physicochemical processes within living organisms. Carbohydrates are polyhydroxy aldehydes or polyhydroxy ketones having general formula (CH 2 O) n. Carbohydrates are the most found compounds in nature and the important structural parts of all living organisms.
