3
Name an important Triose molecule
Glyceraldehyde
what is Glycogen made up of
Alpha Glucose
Is Fructose soluble
Yes
What is Galactose important in the production of
Glycolipids and Glycoproteins
Name two important important pentose molecules
Ribose and Deoxyribose
What is a condensation reaction
A reaction where water is removed from a reaction and from this bonds are made.
What bond forms between monosaccharides
glyosidic bond
what is maltose made up of
2 glucose molecules
what is lactose made up of
Glucose and Galactose
What is Sucrose made up of
fructose and Glucose
What type of sugars are Galactose and Fructose
Hexose sugars
What is the definition of a polysaccharide
polysaccharides are polymers containing many monosaccharides linked by glyosidic bonds
What is the function/ purpose of polysaccharides
Mainly to be used as energy store and as structural components of cells
Name 3 examples of polysaccharides
Starch, Glucose and Glycogen
What is a cellulose molecule made up of
Beta Glucose
What is a Hydrolysis reaction
A reaction where water is added and bonds are broken
How many carbons does glycerol have
3
In what reaction is an ester bond usually formed
A condensation reaction
What groups does an Ester bond form between
One of the OH groups of the Glycerol and, on the COOH groups of the Fatty Acids
What is the difference between a Saturated Fatty acid and a Un-saturated Fatty Acid.
A saturated fatty acid only contain single bonds between carbon atoms creating a straight line. Unlike, Unsaturated Fatty Acids which contain double carbon bonds between carbon atoms creating a ‘kink’ in the chain.
What are the 3 main roles of a lipid
- ) Energy source
- ) Insulation
- ) Protection
What does Hydrophilic mean
Enjoys and likes water.
