The mind is a marvelous organ. And it"s a hungry one, too. The major fuel because that the mind is glucose—a carbohydrate. The mean adult mind represents around (2\%) of ours body"s weight, however uses (25\%) of the glucose in the body. Moreover, details areas that the brain use glucose at various rates. If you space concentrating hard (taking a test, because that example), particular parts that the mind need a most extra glucose, while other parts the the mind only use their normal amount.
You are watching: Which one of the following is an example of a monosaccharide?
Some foodstuffs that space high in carbohydrates incorporate bread, pasta, and potatoes. Because carbohydrates are conveniently digested, athletes frequently rely top top carbohydrate-rich foods to allow a high level that performance.
The hatchet carbohydrate comes from the truth that the majority contain carbon, hydrogen, and oxygen in a ratio of 1:2:1, making for an empirical formula the (ceCH_2O). This is somewhat misleading, because the molecules room not actually hydrates that carbon in ~ all. Carbohydrates room monomers and polymers the aldehydes and also ketones that have actually multiple hydroxyl groups attached.
Carbohydrates space the most abundant source of energy discovered in most foods. The easiest carbohydrates, also called basic sugars, are numerous in fruits. A monosaccharide is a carbohydrate consisting of one street unit. Common examples of an easy sugars or monosaccharides room glucose and also fructose. Both of this monosaccharides are described as hexoses, due to the fact that they have six carbons. Glucose is plentiful in plenty of plant sources, and makes up sweeteners such as corn sugar and also grape sugar. Fructose is foundin countless fruits, and in honey. This sugars space structural isomers the one another, with the distinction being the glucose includes an aldehyde sensible group, whereas fructose contains a ketone useful group.
Glucose and fructose are both really soluble in water. In aqueous solution, the predominant forms are not the straight-chain structure displayed above. Rather, they adopt a cyclic structure (see figure below). Glucose is 6 membered ring, while furustos is a five-membered ring. Both ring contain one oxygen atom.
Another necessary group of monosaccharides space the pentoses, containing five carbons in the chain. Ribose and deoxyribose room two pentoses that are materials of the frameworks of DNA and RNA.

SummaryCarbohydrates are monomers and polymers the aldehydes and also ketones that have multiple hydroxyl teams attached. A monosaccharide is a carbohydrate consist of of one street unit. Usual examples of straightforward sugars or monosaccharides are glucose and fructose. One more important group of monosaccharides space the pentoses, containing five carbons in the chain; DNA and also RNA space partly made up of pentoses.
