UPDATE
Low Density Lipoprotein
"bad cholesterol," builds up within vessels of the body
Essential Elements
elements that are required for human life and are abundant
Trace Elements
elements that are required for human life but only in small amounts
6 predominate elements in living organisms
oxygen, carbon, hydrogen, nitrogen, calcium, and phosphate
Ions
atoms of molecules with net negative or positive charge
Cations
positively charged ions
,Anions
negatively charged ions
Ionic Bonds
formed when ions of molecules of opposite charge are attracted to each other
relatively stable
typically metal + nonmetal
Covalent Bond
formed when electrons are shared equally between two atoms to complete the valence
shells of both
strong
typically nonmetal + nonmetal
Polar Covalent Bond
formed when electrons are shared unequally between 2 atoms to complete the valence
shells of both
-results in partial negative and positive charges in the bonded atoms
-allows hydrogen bonding
Hydrogen Bond
formed by electrostatic interactions between molecules with polar covalent bonds
, weak
Macromolecules
large polymeric molecule made up of many covalently bonded monomers
Biomacromolecules
carbohydrates, lipids, proteins, nucleic acids (DNA/RNA)
Carbohydrate Major Function
energy metabolism
Lipid Major Function
energy, structural, regulatory
Protein Major Function
regulation, structure, transport, protection
Nucleic Acid Major Function
regulation, hereditary, protein synthesis
