---|---|
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 |
