IB Biology: B1.1-Monosaccharides

Front

What are monosaccharides?

Back

Monosaccharides are the simplest types of carbohydrates and act as monomers to make larger complex carbohydrate molecules.

Front

Can monosaccharides be broken down into smaller molecules by hydrolysis?

Back

No, monosaccharides cannot be broken down into smaller molecules by hydrolysis.

Front

How many carbon atoms do monosaccharides have?

Back

Monosaccharides have between 3 to 6 carbon atoms.

Front

What forms when two monosaccharide monomers are joined?

Back

Two monosaccharide monomers may be joined via a glycosidic linkage to form a disaccharide by a condensation reaction.

Front

What is formed when several monomer units are linked together?

Back

Several monomer units linked together form a polysaccharide.

Front

How are monosaccharides classified?

Back

Monosaccharides are classified by the number of carbon atoms they contain: trioses (3 carbon atoms), tetroses (4 carbon atoms), pentoses (5 carbon atoms), hexoses (6 carbon atoms).
