Ko ngā lipids te rōpū tino rerekē o ngā matū koiora. Ko ō rātau whakamahinga hanganga matua hei wāhanga o ngā ārai koiora ā-roto, ā-waho hoki, pēnei i te ārai pūtau, hei pūtake pūngao rānei. Ko ngā lipids te tikanga e tautuhia ana hei rāpoi koiora hydrophobic, amphipathic rānei, engari ka rewa i roto i ngā rongoā rauropi pēnei i te waipiro, te benzene, te chloroform rānei. Ko ngā ngako he rōpū nui o ngā pūhui kei roto i ngā waikawa ngako me te glycerol; he rāpoi ngota glycerol e piri ana ki ngā esters waikawa ngako e toru e kiia ana ko te triacphylglyceride. He maha ngā rerekētanga i runga i tēnei hanganga, tae atu ki ngā kōpeketanga rerekē pēnei i te sphingosine i roto i ngā sphingolipid, me ngā rōpū hydrophilic pēnei i te phosphate i roto i ngā phospholipids.
