Lecture 3 Flashcards
(23 cards)
large molecule
macromolecule
one that contais many atoms covalently bonded to one another
macromolecule
macromolecule made up of smaller subunits are called
monomers
what are the classes if macromolecules that exist as polymers
proteins, nucleic acid, and carbihydrates
how do monomers come together to form polymers
polymerization
polymerization occurs via ______ reaction
dehydration
polymers are broken apart via _______ reactions
hydrolysis
what is the monomer of protein
amino acids
how do amino acids differ in their properties
due to variation in R groups
what are the 3 categories of R groups
charged, uncharged polar , nonpolar
are charge R groups hydrophobic or hydrophilic
hydrophilic
Charged R groups are both acidic and basic. TRUE OR FALSE
true
are polar R groups hydrophobic or hydrophilic
hydrophilic
what can polar R groups form
H bonds with water
are nonpolar R groups hydrophobic or hydrophilic
hyrdrophobic
how are amino acids polymerized
via dehydration reaction
what is the resulting C-N bond
peptide bond
what are interacting in peptide bonds
oxygen on the carboxyl end and the nitrogen on the amino end
polymer of fewer than 50 amio acids
oligopeptide
polymer of more than 50 amino acids
polypeptide
refers to the completely folded and functional form of that chain
protein
what does amino acid sequence determine?
protein’s 3d structure
refers to the sequence of amino acids in the oligopetide or polypetdie
primary structure
