Biological Molecules: Monosaccharides Flashcards
1
Q
What do ALL carbohydrates contain?
A
= ONLY 3 ELEMENTS
= Carbon + Hydrogen + Oxygen.
2
Q
What is a hexose sugars?
A
= sugars with 6 carbon atoms.
3
Q
What are single-sugar molecules called?
A
= Monosaccharides
= E.g: Glucose, Galactose, Fructose.
=
4
Q
What is the first property of Monosaccharides?
A
= soluble in water + hydrophilic.
= contains large amount of OH groups- hydroxyln groups
= form hydrogen bonds with water molecules
5
Q
What does hydrophilic mean?
A
= dissolve in water
= water loving.
6
Q
What are Monosaccharides with 5 carbon atoms called?
A
= Pentose.
E/g: Ribose.
7
Q
What are polysacharides or dissacharides?
A
= Monosacharides can be chemically joined together to form larger carbonhydrates.
