How are disaccharides formed

When two monosaccharides chemically react together

When we make a disaccharide, we also produce a molecule of water, water molecule is formed from a hydrogen atom from one of the monosaccharides, and hydroxyl group from other. This is called condensation reaction

What happens when two alpha glucose molecules react

Creates the disaccharide called maltose.

<p>Whats a glycosidic bond</p>

Whats a glycosidic bond

Strong covalent bond that joins two carbohydrates together.

New cards

Whats a 1,4 glycosidic bond

Because its connected to carbon 1 on one alpha glucose and carbon 4, it is called 1,4 glycosidic bond

How do we break glycosidic bond in a disaccharide

If we add water.

Converts disaccharide back to original monosaccharides, this is called hydrolysis reaction.
