|water ||-solvent in w/c rxns take place.
-80% of cell mass is made of water.
-polar mol w/ H-bonds
-able to stay liquid bc of h-bonds|
|hydrolysis ||breakdown (separation) of macromolecules by water|
|dehydration ||formation of macromolecules by getting rid of water|
|lipids ||substance w/ low solubility in water and high solubility in non-polar solvents|
|6 major groups of lipids ||fatty acids, triglycerides, phospholipids, glycolipids, steroids, terpenes |
|these are good barriers in aqueous solutions ||lipids|
|building blocks for most complex lipids ||fatty acids|
|fatty acids ||long carbon chains truncated at one end with cooh. usually have an even number of c. UP TO 24 C|
|diff between saturated and unsaturated fatty acids: ||saturated c-c all the way.
unsaturated at least one c=c|
|triglycerides ||fats and oils constructed by a glycerol backbone|
|glycerol ||3 C backbone for fats and oils|
