Faasino i le vaega o loo i lalo ma tali le fesili mulimuli ane i le gagana lava lea e tasi e pei o le vaega:  Faamatalaga: O lipids o vaega ia e sili ona eseese o vailaau o le tino. O a latou fausaga fausaga autu e avea o se vaega o meaola i totonu ma fafo, e pei o le membrane cell, po o se punavai o le malosi. O lipids e masani lava ona faʻamatalaina o hydrophobic poʻo amphipathic biological molecules ae o le a faʻamavae i vailaʻau faʻamaʻi e pei o le ava malosi, benzene poʻo le chloroform. O le gaʻo o se vaega tele o tuufaatasiga o loo i ai gaʻo acids ma glycerol; o se glycerol molecule faapipii i tolu gaʻo acid esters ua taʻua o le triacylglyceride. E tele fesuiaiga o lenei fausaga faavae, e aofia ai le sui o le sphingosine i le sphingolipids, ma vaega hydrophilic e pei o le phosphate e pei o le phospholipids. O isi vaega autū o lipid o vailaau e pei o le cholesterol.  Fesili: e faapefea ona faamatalaina le lipid?
