CARBOHYDRATES
KETONES (OR) POLYHYDROXY ALDEHYDES A Carbohydrate is composed of carbon, hydrogen, and oxygen in the ratio of 1:2:1 (CH 2 O)n. They are of three types namely monosaccharides, disaccharides, and polysaccharides MONOSACCHARIDES These are the simplest form of carbohydrates being comprised of a single organic molecule. Depending on the number of carbon atoms they are classified into trioses, tetroses, pentoses, and hexoses The trioses are common intermediary products in the carbohydrate metabolic process. They play an important role in the interconversion of biomolecules. Pentoses like ribose and deoxyribose are the integral components of RNA and DNA molecules. The Hexoses such as glucose, fructose, and galactose are food components commonly consumed. Carbohydrates are commonly employed by cells for providing energy. The energy metabolism happens through glycolytic processes involving oxidative, citric acid cycle. The energy liberated is stored in the form of ATPs (Adenosine tr...
