verified answers
Water - ** VERIFIED ANSWERS **✔✔H2O, molecular weight=18, oxygen is partial negative
charge, hydrogen has slight positive charge.
What is a dipole moment? - ** VERIFIED ANSWERS **✔✔difference in charge on two ends of a
molecule
Anions - ** VERIFIED ANSWERS **✔✔negatively charged ions
Cations - ** VERIFIED ANSWERS **✔✔positively charged ions
covalent bond - ** VERIFIED ANSWERS **✔✔A chemical bond formed when two atoms share
electrons
hydrogen bond - ** VERIFIED ANSWERS **✔✔Attraction between a slightly positive hydrogen
atom and a slightly negative atom.
osmosis - ** VERIFIED ANSWERS **✔✔diffusion of water through aquaporins
diffusion - ** VERIFIED ANSWERS **✔✔Movement of molecules from an area of higher
concentration to an area of lower concentration.
hydrophilic - ** VERIFIED ANSWERS **✔✔water loving, charged, polar
Hydrophobic - ** VERIFIED ANSWERS **✔✔Water fearing, uncharged, nonpolar
Lipids - ** VERIFIED ANSWERS **✔✔fats, oils. hydrophobic
, Triglycerides - ** VERIFIED ANSWERS **✔✔glycerol (3 carbon alcohol) + 3 fatty acids. use of
esterbond
esterbond - ** VERIFIED ANSWERS **✔✔Carbon-oxygen-fatty acid. uses dehydration
amphipathic molecules - ** VERIFIED ANSWERS **✔✔containing hydrophobic and hydrophilic
regions
phosphate head group - ** VERIFIED ANSWERS **✔✔region of phospholipid bilayer that is
hydrophillic
Micelle - ** VERIFIED ANSWERS **✔✔lipid molecules that arrange themselves in a spherical form
in aqueous solutions. rare and unstable
liposome - ** VERIFIED ANSWERS **✔✔phospholipid molecules organized as a bilayer sphere.
stable.
planar bilayer - ** VERIFIED ANSWERS **✔✔makes up membranes of cells, most stable, both
outside and inside of membrane is hydrophilic (aqueous)
phospholipid bilayer - ** VERIFIED ANSWERS **✔✔A double layer of phospholipids that makes up
membranes. proteins will be involved as a hydrophilic pathway (ion channel)
protein - ** VERIFIED ANSWERS **✔✔amino acid sequence linked by peptide bonds
amino acid structure - ** VERIFIED ANSWERS **✔✔H, NH2, COOH bonded to a central carbon
and then a variable R group
