  2. Lipid - Wikipedia

    en.wikipedia.org/wiki/Lipid

    The fatty acid structure is one of the most fundamental categories of biological lipids and is commonly used as a building-block of more structurally complex lipids. The carbon chain, typically between four and 24 carbons long, [ 23 ] may be saturated or unsaturated , and may be attached to functional groups containing oxygen , halogens ...

  3. Glycerophospholipid - Wikipedia

    en.wikipedia.org/wiki/Glycerophospholipid

    For example sn-glycero-3-phosphoric acid and sn-glycero-1-phosphoric acid are enantiomers. Most vegetable oils have unsaturated fatty acids in the sn-2 position, with saturated fatty acids in the 1-sn and/or 3-sn position. [8] Animal fats more often have saturated fatty acids in the 2-sn, with unsaturated fatty acids in the 1-sn and/or 3-sn ...

  4. Lipid metabolism - Wikipedia

    en.wikipedia.org/wiki/Lipid_metabolism

    Lipid metabolism is the synthesis and degradation of lipids in cells, involving the breakdown and storage of fats for energy and the synthesis of structural and functional lipids, such as those involved in the construction of cell membranes. In animals, these fats are obtained from food and are synthesized by the liver. [1]

  5. Category:Lipids - Wikipedia

    en.wikipedia.org/wiki/Category:Lipids

    Lipids are a class of relatively water-insoluble organic molecules, which are the "basic" components of biological membranes. There are three forms of lipids: phospholipids , steroids , and triglycerides .

  6. Lipidomics - Wikipedia

    en.wikipedia.org/wiki/Lipidomics

    Examples of various lipid species. Lipidomics is the large-scale study of pathways and networks of cellular lipids in biological systems. [1] [2] [3] The word "lipidome" is used to describe the complete lipid profile within a cell, tissue, organism, or ecosystem and is a subset of the "metabolome" which also includes other major classes of biological molecules (such as amino acids, sugars ...

  7. Membrane lipid - Wikipedia

    en.wikipedia.org/wiki/Membrane_lipid

    Membrane lipids are a group of compounds (structurally similar to fats and oils) which form the lipid bilayer of the cell membrane. The three major classes of membrane lipids are phospholipids, glycolipids, and cholesterol. Lipids are amphiphilic: they have one end that is soluble in water ('polar') and an ending that is soluble in fat ...

  8. Lipogenesis - Wikipedia

    en.wikipedia.org/wiki/Lipogenesis

    In biochemistry, lipogenesis is the conversion of fatty acids and glycerol into fats, or a metabolic process through which acetyl-CoA is converted to triglyceride for storage in fat. [1] Lipogenesis encompasses both fatty acid and triglyceride synthesis , with the latter being the process by which fatty acids are esterified to glycerol before ...

  9. Saponifiable lipid - Wikipedia

    en.wikipedia.org/wiki/Saponifiable_lipid

    The primary saponifiable lipids are free fatty acids, neutral glycerolipids, glycerophospholipids, sphingolipids, and glycolipids. [ 1 ] By comparison, the non-saponifiable class of lipids is made up of terpenes, including fat-soluble A and E vitamins, and certain steroids, such as cholesterol.
