  3. Fatty acid - Wikipedia

    en.wikipedia.org/wiki/Fatty_acid

    The chemical analysis of fatty acids in lipids typically begins with an interesterification step that breaks down their original esters (triglycerides, waxes, phospholipids etc.) and converts them to methyl esters, which are then separated by gas chromatography [41] or analyzed by gas chromatography and mid-infrared spectroscopy.

  4. Animal fat - Wikipedia

    en.wikipedia.org/wiki/Animal_fat

    Animal fats are lipids derived from animals which are used by the animal for a multitude of functions, or can be used by humans for dietary, sanitary, and cosmetic purposes. Depending on the temperature of the fat, it can change between a solid state and a liquid state. Chemically, both fats and oils are composed of triglycerides.

  5. Monounsaturated fat - Wikipedia

    en.wikipedia.org/wiki/Monounsaturated_fat

    Algal oil is about 92% monounsaturated fat. Olive oil is about 75% monounsaturated fat. [10] The high oleic variety sunflower oil contains at least 70% monounsaturated fat. [11] Canola oil and cashews are both about 58% monounsaturated fat. [citation needed] Tallow (beef fat) is about 50% monounsaturated fat. [12] and lard is about 40% ...

    Polyunsaturated fatty acids are precursors to and are derived from polyunsaturated fats, which include drying oils.

  7. Oil - Wikipedia

    en.wikipedia.org/wiki/Oil

    Most oils are unsaturated lipids that are liquid at room temperature. The general definition of oil includes classes of chemical compounds that may be otherwise unrelated in structure, properties, and uses. Oils may be animal, vegetable, or petrochemical in origin, and may be volatile or non-volatile. [1]

  8. Saturated fat - Wikipedia

    en.wikipedia.org/wiki/Saturated_fat

    A saturated fat is a type of fat in which the fatty acid chains have all single bonds between the carbon atoms. A fat known as a glyceride is made of two kinds of smaller molecules: a short glycerol backbone and fatty acids that each contain a long linear or branched chain of carbon (C) atoms.

  9. Trans fat - Wikipedia

    en.wikipedia.org/wiki/Trans_fat

    Animal-based fats were once the only trans fats consumed, but by far the largest amount of trans fat consumed today is created by the processed food industry as a side effect of partially hydrogenating unsaturated plant fats (generally vegetable oils). These partially hydrogenated fats have displaced natural solid fats and liquid oils in many ...
