What are the different characteristics of carbohydrates?
The common attributes of carbohydrates are that they contain only the elements carbon, hydrogen and oxygen, and that their combustion will yield carbon dioxide plus one or more molecules of Water.
What are 3 characteristics of monosaccharides?
Monosaccharides are classified according to three different characteristics: the position of the carbonyl group, the number of carbon atoms, and its chiral handedness.
What are the characteristics of disaccharides?
Characteristics of Disaccharides Similar to other carbohydrates, disaccharides are comprised of hydrogen, carbon, and oxygen, and the ratio of hydrogen atoms to oxygen atoms is often 2:1, which explains why they are referred to as hydrates of carbon. The general chemical formula of disaccharides is C12H22O11.
What are the different classifications of monosaccharides?
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.
What are the properties of monosaccharides?
Physical properties of monosaccharides
- Colour and shape. Monosaccharides are colourless and crystalline compounds.
- Solubility. They are readily soluble in water.
- Taste. They have sweet tase.
- Stereo isomerism. D-glucose and L-glucose are mirror images of each other.
- Optical Isomerism.
- Mutarotation.
What is the difference between monosaccharides and disaccharides give two examples for each?
Glucose and fructose are examples of monosaccharides. Disaccharides are carbohydrates made of two monosaccharides and with the loss of one molecule of water dehydration. The chemical bond between two monosaccharides is known as a glycosidic bond.
What are monosaccharides oligosaccharides and polysaccharides What is the difference between monosaccharides and disaccharides What are some examples of them?
Oligosaccharides contain glycosidic linkages (acetal or ketal) that release two or more monosaccharide units upon hydrolysis. Disaccharides are oligosaccharides that contain two monosaccharide units. Polysaccharides contain a large number of monosaccharide units bonded to each other by a series of glycosidic bonds.
What is the biological importance of monosaccharides disaccharides and polysaccharides?
The ribose and deoxyribose monosaccharides are vital elements of RNA and DNA, which are the building blocks of life. While monosaccharides cannot be broken down into smaller sugars, disaccharides and polysaccharides are broken down into monosaccharides in processes like digestion.
