What is glucose?

A hexose monosaccharide sugar contain in six carbons. Furthermore, it is the main substrate for respiration where it is oxidized to release energy

2
New cards

What is the formula for glucose, furthermore what are the two isomers of glucose?

C6H12O6. it can exist as alpha or beta glucose

3
New cards

How is the six membered glucose ring created?

In glucose carbon atom-1 combines with carbon atom-5, forming is six membered ring

4
New cards

What is the difference between the alpha and beta glucose molecules

In the alpha glucose, the hydroxyl group of carbon 1 projects below.

Whereas in beta glucose, the hydroxyl group of carbon-1 projects above

What is sucrose

A disaccharide with the formula C12H22O4 consisting of two simple sugars, glucose and fructose, normal culinary sugar

6
New cards

Characteristics of sucrose

Sucrose is common table sugar.

It is a disaccharide, a molecule composed of two monosaccharides: glucose and fructose.

Sucrose is produced naturally in plants, in this form, sucrose is transported through cell sap. Sucrose has 1, 2-glycosidic bonds

7
New cards

Therefore what molecules are needed to create a sucrose molecule and what type of reaction will occur in the process

Sucrose is made via a condensation reaction between alpha glucose and fructose

8
New cards

Why does sucrose has a good ability to be transported

This is because it is soluble, relatively unreactive chemically and has the ability to move efficiently in large concentrations
