Introduction:
The term ‘’Carbohydrates’’ is defined as the carbon compounds which contains hydroxyl groups in large quantities (King, 2013). Carbohydrates are those organic compounds that have the empirical formula CnH2nOn, or (CH2O)n (Fromm 1997). Carbohydrates are one of the four types of organic compounds in living cells that are produces during photosynthesis and are the important source of energy in both plants and animals (Ahmed 2014). They are built from monosaccharides. These monosaccharides are the small molecule that consists of three to nine carbon atoms and differ in size and in the s configuration at one or more carbon centers. The simplest carbohydrates also contain either an aldehyde or ketone compounds (Berg, Tymoczko & Stryer 2002). Carbohydrates are classified as simple and complex carbohydrates. The classification of carbohydrates is based on the chemical structure of the food and how fast it absorbs. A simple carbohydrate contains single or double sugars in their chemical structure whereas a complex carbohydrate consists of three or more sugars (Ahmed 2014). There are four major types of carbohydrates depending on their chemical composition.
1) Monosaccharides: Mono means single and saccharides refer to sugar. These are the simple form of carbohydrates that consists carbon, hydrogen and oxygen in the ratio of 1:2:1 (Ahmed…
