Unit 1.1 Biological Molecules Flashcards
Explain how all living things have a similar biochemical basis
Quickly summarise, what is a monomer?
Smaller units from which larger molecules are made
Describe polymers
And state what they are made from
…
They are made from a large number of polymers
Name examples of monomers
Monosaccharides
Amino acids
Nucleotides
…
What reaction joins to molecules together? Describe how this happens.
What bond does this form? How?
Condensation reaction
…
A condensation reaction forms a chemical bond and involves the elimination of a water molecule.
A condensation reaction between two monosaccharides form a glycosidic bond.
Decried what a hydrolysis reaction does
It breaks a chemical bond between two molecules, involving the use of a water molecule
What are monosaccharide monomers?
Monomers from which larger carbohydrates are made
List some common monosaccharides
Glucose
Galactose
Fructose
What are disaccharides?
Disaccharides are formed by the condensation of two monosaccharides
A condensation reaction occurs between two glucose molecules, what disaccharide is formed?
Maltose
A condensation reaction occurs between a glucose molecule and a fructose molecule, what disaccharide is formed?
Sucrose
A condensation reaction occurs between a glucose molecule and a galactose molecule, what disaccharide is formed?
Lactose
How many isomers does glucose have?
What are they?
How does glucose have two isomers?
2
