Triose.
Tetrose.
Pentose.
Hexose.

10
Q

What are the most common sugars called?

A

Hexose sugars.

11
Q

What do pentose and hexose sugars tend to form ?

A

Ring structures.

12
Q

How is ‘a glucose’ formed?

A

When the OH at C1 is below the plane of the ring.

13
Q

How is ‘b glucose’ formed?

A

When the OH at C1 is above the plane of the ring.

14
Q

monosaccharides can be bonded together with a condensation reaction to form what?

A

Glycosidic bond.

15
Q

What can the glycosidic bond be broken by?

A

Hydrolysis.

16
Q

What is the bond named after?

A

The carbon atoms that are involved in the bond.

17
Q

A monosaccharide is how many sugars?

A

One sugar.

Simple sugars.

18
Q

What is the difference between ‘a glucose’ and ‘b glucose’?

A

The hydrogen and hydroxide are swapped over on the first carbon.
Huge impact when glucose forms polymers.
