What is the general formula for a monosaccharide and give two examples?
Monosaccharides include aldoses, ketoses, and their derivatives. The general chemical formula for a monosaccharide is CnH2nOn or (CH2O)n. Examples of monosaccharides include the three most common forms: glucose (dextrose), fructose (levulose), and galactose.
What is the general formula for any carbohydrates?
The general formula for any carbohydrate is (CH2O)x where x is any number between three and eight. The most common monosaccharides (hexoses) are glucose, galactose, and fructose. Glucose is the simplest monosaccharide and probably the most familiar sugar, especially if you have been in the hospital.
What is the chemical structure of monosaccharides?
All monosaccharides have the same general formula of (CH2O)n, which designates a central carbon molecule bonded to two hydrogens and one oxygen. The oxygen will also bond to a hydrogen, creating a hydroxyl group. Because carbon can form 4 bonds, several of these carbon molecules can bond together.
What is monosaccharide example?
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). Some other monosaccharides can be converted in the living organism to glucose.
What does a monosaccharide look like?
Monosaccharides are simple sugars made up of three to seven carbons, and they can exist as a linear chain or as ring-shaped molecules. Glucose, galactose, and fructose are monosaccharide isomers, which means they all have the same chemical formula but differ structurally and chemically.
Which is not monosaccharide?
The correct answer is option (D) Sucrose. Sucrose is not a monosaccharide. Sucrose consists of glucose and galactose. Hence, sucrose is a disaccharide.
