Define monosaccharide disaccharide polysaccharide

Answer 1

Monosaccharides and DisaccharidesIn the category of nutrients, there are monomers and polymers. Monomers are the "building blocks" of large macromolecules, or any molecule chain created through condensation reactions. These are the polymers, three or more monomers bonded together.

In the category of carbohydrates, there are monosaccharides, disaccharides, oligosacchaides, and polysaccharides. Just from the prefixes, you can tell that the monosaccharides are monomers, the disaccharides are two bonded monomers (monosaccharides) and oligosacchaides and polysaccharides are made up of many monomers (monosaccharides).

The monosaccharides are just a single carbon ring (in the natural aqueous environment of an organism). The monosaccharides include glucose, fructose, and galactose. The disaccharides are two carbon rings bonded together by a glycosidic linkage in a condensation (dehydration) reaction, which removes a molecule of water. Disaccharides include maltose (glucose + glucose), lactose (glucose + galactose), sucrose (glucose + fructose), and more.

When we consume food, we are taking in the large polysacchaides such as starch and smaller molecules such as maltose. We take these long molecules and digest them - break up their glycosidic linkages until they are monosaccharides (monomers) that we can absorb throughout out alimentary canal (usually in small intestine).
A monosaccharide is one saccharide (or sugar) molecule. An example of a monosaccharide is glucose.

A disaccharide is two saccharides (sugars) bonded together through a dehydration reaction. An example of a disaccharide is maltose which is two glucose linked together.

A polysaccharide is typically ten or more saccharides bonded together. Cellulose is an example of a polysaccharide, which is ten or more glucose linked together.

Answer 2

All three are kinds of carbohydrates. Monosaccharides are fairly simple sugars, having only one unit. Disaccharides are only slightly more complex, having two units hooked together. A polysaccharide is the most complex, consisting of large numbers of sugars in specific formations.

Answer 3

Monosaccharide: a carbohydrate that does not hydrolyze, as glucose, fructose, or ribose, occurring naturally or obtained by the hydrolysis of glycosides or polysaccharides.

Disaccharide: any of a group of carbohydrates, as sucrose or lactose, that yield monosaccharides on hydrolysis.

Polysaccharide: a carbohydrate, as starch, inulin, or cellulose, containing more than three monosaccharide units per molecule, the units being attached to each other in the manner of acetals, and therefore capable of hydrolysis by acids or enzymes to monosaccharides.

Answer 4

a monosaccharide is a single sugar molecule, a disachharide is a double sugar molecule, and a polysaccharide has three or more sugar molecules.

Answer 5

They are sugars. Glucose and Fructose are monos, sucrose (table sugar) is di, and starch is poly, for example.

Answer 6

Disuccharides are made up of two monosacchardies combined together, while polysaccharide is the largest carbonhydrate molecule.

Answer 7

monosaccharides(sweet) are made of a single glucose molecule, disaccharides(also sweet) are made of two glucose molecules,

while polysaccharides(starchy) are made of more than 2 glucose molecules.

Answer 8

the number of monomers in the molecule
