(11 cards)
what is a monomer
basic structural unit of polymers
what is a polymer
molecule made up of a of identical or similar units (monomers) attached by covalent bonds
what is a macromolecule
1000s of atoms linked together by covalent bonds
what type of reaction is it when :
-monomers are joined to form polymers
-ATP is needed and the reaction is usually catalyzed by an enzyme
-the type of metabolism is anabolism
dehydration synthesis
what type of reaction is it when:
-breakdown of polymers into monomers by the addition of water
-reaction produces ATP and is usually catalyzed by an enzyme
-the type of metabolism is catabolism
hydrolysis
what are some properties of polar functional groups?
-they tend to make h-bond between electronegative elements
-hydrophilic
what are some properties of non-polar functional groups?
-hydrophobic (arrange themselves together away from water molecules)
which functional groups are polar?
-hydroxyl
-carbonyl
-sulfhydryl (slightly polar)
-phosphate
-carboxyl
-amino
which functional group is non-polar?
-methyl
which functional groups are either acidic or basic?
-carboxyl (acidic)
-phosphate (acidic)
-amino (basic)
what is the name of the bond that links to disaccharides (the one between 2 hydroxyl groups)
glycosidic bond
