Basics Flashcards
Monomer
smaller units that join together to form larger molecules
E.g of monomer
-amino acids
-nucleotides
Polymer
Molecules formed when many monomers join together
E.g of polymers
-Proteins
-DNA/RNA
What happens in a condensation reaction?
-chemical bond forms between 2 molecules and a molecule of water is released
What happens in a hydrolysis reaction?
-Water molecule is used to break a chemical bond between 2 molecules
Name the 3 hexose monosaccharides
-glucose
-fructose
-galactose
Monosaccharide
Single monomer units
Disaccharide
Formed when two monosaccharides are joined together in a condensation reaction
Polysaccharides
Formed when many monosaccharides are joined together in a condensation reaction
Bond formed when monosaccharides react
glycosidic (1,4 or 1,6)
Examples of disaccharides
maltose, sucrose, lactose
How does maltose form
condensation reaction between glucose and glucose
How does sucrose form
condensation reaction between glucose and fructose
How does lactose form
condensation reaction between glucose and galactose
Examples of polysaccharides
Cellulose, starch, glycogen
