  2. Fatty acid - Wikipedia

    en.wikipedia.org/wiki/Fatty_acid

    Fatty acids exhibit reactions like other carboxylic acids, i.e. they undergo esterification and acid-base reactions. Fatty acids do not show a great variation in their acidities, as indicated by their respective pK a. Nonanoic acid, for example, has a pK a of 4.96, being only slightly weaker than acetic acid (4.76).

  3. Essential fatty acid - Wikipedia

    en.wikipedia.org/wiki/Essential_fatty_acid

    Essential fatty acids, or EFAs, are fatty acids that are required by humans and other animals for normal physiological function that cannot be synthesized in the body. [ 1 ] [ 2 ] ⁠ As they are not synthesized in the body, the essential fatty acids – alpha-linolenic acid (ALA) and linoleic acid – must be obtained from food or from a ...

    Cervonic acid (or docosahexaenoic acid) has 22 carbons, is found in fish oil, is a 4,7,10,13,16,19-hexa unsaturated fatty acid. In the human body its generation depends on consumption of omega 3 essential fatty acids (e.g., ALA or EPA), but the conversion process is inefficient. [ 22 ]

  6. Fatty acid metabolism - Wikipedia

    en.wikipedia.org/wiki/Fatty_acid_metabolism

    A significant proportion of the fatty acids in the body are obtained from the diet, in the form of triglycerides of either animal or plant origin. The fatty acids in the fats obtained from land animals tend to be saturated, whereas the fatty acids in the triglycerides of fish and plants are often polyunsaturated and therefore present as oils.

  7. Unsaturated fat - Wikipedia

    en.wikipedia.org/wiki/Unsaturated_fat

    Studies on bird fatty acid composition have noted similar proportions to mammals but with 1/3rd less omega-3 fatty acids as compared to omega-6 for a given body size. [10] This fatty acid composition results in a more fluid cell membrane but also one that is permeable to various ions (H+ & Na+), resulting in cell membranes that are more costly ...

  8. Fat - Wikipedia

    en.wikipedia.org/wiki/Fat

    Fatty acids, monoglycerides (one glycerol, one fatty acid), and some diglycerides are absorbed by the duodenum, once the triglycerides have been broken down. In the intestine , following the secretion of lipases and bile , triglycerides are split into monoacylglycerol and free fatty acids in a process called lipolysis .

  9. 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.
