Answer: glucose
what is the major monosaccharide found in the body?

Monosaccharides (from Greek monos: single sacchar: sugar) also called simple sugars are the simplest form of sugar and the most basic units (monomers) of carbohydrates. The general formula is C nH 2nO n albeit not all molecules fitting this formula (e.g. acetic acid) are carbohydrates. They are usually colorless water-soluble and crystalline solids. Contrary to their name (sugars) only some monosacchari…

Monosaccharides (from Greek monos: single sacchar: sugar) also called simple sugars are the simplest form of sugar and the most basic units (monomers) of carbohydrates. The general formula is C nH 2nO n albeit not all molecules fitting this formula (e.g. acetic acid) are carbohydrates. They are usually colorless water-soluble and crystalline solids. Contrary to their name (sugars) only some monosaccharides have a sweet taste. Examples of monosaccharides include glucose (dextrose) fructose (levulose) and galactose. Monosaccharides are the building blocks of disaccharides (such as sucrose and lactose) and polysaccharides (such as cellulose and starch). Each carbon atom that supports a hydroxyl group is chiral except those at the end of the chain. This gives rise to a number of isomeric forms all with the same chemical formula. For instance galactose and glucose are both aldohexoses but have different physical structures and chemical properties. The monosaccharide glucose plays a pivotal role in metabolism where the chemical energy is extracted through glycolysis and the citric acid cycle to provide energy to living organisms. Some other monosaccharides can be converted in the living organism to glucose.

With few exceptions (e.g. deoxyribose ) monosaccharides have this chemical formula : (CH2O)x where conventionally x ≥ 3. Monosaccharides can be classified by the number x of carbon atoms they contain: triose (3) tetrose (4) pentose (5) hexose (6) heptose (7) and so on.

Glucose used as an energy source and for the synthesis of starch glycogen and cellulose is a hexose . Ribose and deoxyribose (in RNA and DNA respectively) are pentose sugars. Examples of heptoses include the ketoses mannoheptulose and sedoheptulose . Monosaccharides with eight or more carbons are rarely observed as they are quite unstable. In aqueous solutions monosaccharides exist as rings if they have more than four carbons. Linear-chain monosaccharides Simple monosaccharides have a linear and unbranched carbon skeleton with one carbonyl (C=O) functional group and one hydroxyl (OH) group on each of the remaining carbon atoms . Therefore the molecular structure of a simple monosaccharide can be written as H(CHOH)n(C=O)(CHOH)mH where n + 1 + m = x; so that its elemental formula is CxH2xOx. By convention the carbon atoms are numbered from 1 to x along the backbone starting from the end that is closest to the C=O group. Monosaccharides are…
