Is galactose a monosaccharide disaccharide or polysaccharide?

Is galactose a monosaccharide disaccharide or polysaccharide?

Glucose, galactose, and fructose are common monosaccharides, whereas common disaccharides include lactose, maltose, and sucrose. Starch and glycogen, examples of polysaccharides, are the storage forms of glucose in plants and animals, respectively. The long polysaccharide chains may be branched or unbranched.

Is galactose a polysaccharide?

The major component in the rigid cell walls in plants is cellulose and is a linear polysaccharide polymer with many glucose monosaccharide units….

Is galactose a disaccharide?

Galactose is a monosaccharide. When combined with glucose (monosaccharide), through a condensation reaction, the result is a disaccharide called lactose.

What is galactose in biology?

Galactose, a C4 epimer of glucose, is a hexose widely used to build up biologically functional glycoconjugates in living organisms. When combined with glucose through covalent bonds, it makes the widely known lactose, a disaccharide largely found in milk.

Is Ribose a monosaccharide disaccharide or polysaccharide?

Structure. Ribose is an aldopentose (a monosaccharide containing five carbon atoms) that, in its open chain form, has an aldehyde functional group at one end.

What is galactose structure?

C6H12O6
Galactose/Formula

What is structure of galactose?

Is galactose a Dextrorotatory?

Galactose is dextrorotatory…as it rotates polarised light towards right side…

What foods contain monosaccharides?

Fruits. Fruits,especially apples,cherries,grapes,guavas,lichees,honeydew melon,watermelon,mangoes,papayas,pears,persimmons and pineapple,are the richest whole-food sources of the monosaccharide fructose.

Is galactose a reducing sugar?

The common dietary monosaccharides galactose, glucose and fructose are all reducing sugars. Disaccharides are formed from two monosaccharides and can be classified as either reducing or nonreducing.

Is galactose a pentose or hexose?

Glucose, galactose, and fructose are all hexoses . They are structural isomers, meaning they have the same chemical formula (C6H12O6) but a different arrangement of atoms. What kind of sugars are these, aldose or ketose? Click to Show Answer

Is galactose a monomer?

A monomer is a molecule that bonds with other identical molecules to form polymers. In this case, the correct answer is glucose, but galactose and fructose also belong in the monomer group, just aren’t mentioned in the question.
