Carbohydrates and Biochemistry. • Carbohydrates are compounds of tremendous biological importance: – they provide energy through oxidation. – they supply carbon for the synthesis of cell components. – they serve as a form of stored chemical energy. – they form part of the structures of some cells and tissues. Feb 9, On Jan 1, , Dr. Suman Khowala (and others) published the chapter: Carbohydrates in the book: Biomolecules (Introduction, Structure and Functions). Dec 21, Carbohydrates are the most widely distributed and abundant organic compounds on earth. They have a central role in the metabolism of animals and plants. Carbohydrate biosynthesis in plants starting from carbon dioxide and water with the help of light energy, i. e., photosynthesis, is the basis for the.
arbohydrates are a major class of naturally occurring organic com- pounds, which come by their name because they usually have, or approximate, the general formula C,,(H,O),,,, with n equal to or greater than three. Among the well- known carbohydrates are various sugars, starches, and cellulose, all of which are important. Chapter 12 Lecture Notes: Carbohydrates. Educational Goals. 1. Given a Fischer projection of a monosaccharide, classify it as either aldoses or ketoses. 2. Given a Fischer projection of a monosaccharide, classify it by the number of carbons it contains. 3. Given a Fischer projection of a monosaccharide, identify it as a. Fischer projections of carbohydrates have the carbonyl. (C=O) at the top. It is projecting away from the viewer behind the plane in which it is drawn as is the other vertical bond at the bottom of the image. • The hydroxyl group on the chiral carbon farthest from the C=O group determines whether the carbohydrate is D ( OH on.
Mar 14, An Introduction to Carbohydrates. • Carbohydrates are a large class of naturally occurring polyhydroxy aldehydes and ketones. • Monosaccharides also known as simple sugars, are the simplest carbohydrates containing carbon atoms. • sugar containing an aldehydes is known as an aldose. Technically, carbohydrates are any compound containing carbon, hydrogen, and oxygen, with twice as many hydrogens as oxygens. They are the main energy source for the body and the only direct energy source for the brain. Carbohydrates can be found in varying amounts in fruits, vegetables, grain foods, and many. ,9/ Neuman.
