Note: An ester of a long-chain fatty acid (such as stearic acid or palmitic acid), of plant or animal origin, that is that is nonvolatile, insoluble in water, oily or greasy to the touch, and solid at room temperature. Chemically, fats are identical to animal and vegetable oils, consisting primarily of glycerides, which are esters formed by the reaction of three molecules of fatty acids with one molecule of glycerol. Pure fats are colorless, odorless, tasteless and will float on water. Examples of natural fats are butter, lard and tallow. Fats may be hydrolyzed with an alkali to form soap in a process called saponification. Fats are also used in leather tannage, paints, and protective coatings.

Additional Notes: |

| Dutch ..... Een ester van vetzuur met lange ketens (zoals stearinezuur of palmitinezuur), van plantaardige of dierlijke oorsprong, die niet vluchtig is, niet oplosbaar in water, olieachtig of vettig aanvoelt en bij kamertemperatuur een vaste stof is. Chemisch gezien zijn vetten identiek aan dierlijke of plantaardige olie, die voornamelijk bestaan uit glyceriden: esters gevormd door de reactie van drie moleculen vetzuur met één molecuul glycerol. Pure vetten zijn kleurloos, geurloos en smaakloos en blijven drijven op water. Voorbeelden van natuurlijke vetten zijn boter, reuzel en talg. Wanneer vetten worden gehydrolyseerd met alkali kunnen ze zeep vormen in een proces dat 'verzeping' wordt genoemd. Vetten worden ook gebruikt voor leerlooien en in verf en beschermlagen. |
