  2. 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 ...

  3. Lipid droplet - Wikipedia

    en.wikipedia.org/wiki/Lipid_droplet

    Lipid droplets, also referred to as lipid bodies, oil bodies or adiposomes, [1] are lipid-rich cellular organelles that regulate the storage and hydrolysis of neutral lipids and are found largely in the adipose tissue. [2] They also serve as a reservoir for cholesterol and acyl-glycerols for membrane formation and maintenance.

  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 ...

  5. Cholesterol - Wikipedia

    en.wikipedia.org/wiki/Cholesterol

    As a rule of thumb, the epidermal lipid matrix is composed of an equimolar mixture of ceramides (≈50% by weight), cholesterol (≈25% by weight), and free fatty acids (≈15% by weight), with smaller quantities of other lipids also being present. [35] [36] Cholesterol sulfate reaches its highest concentration in the granular layer of the ...

  6. Lipoprotein - Wikipedia

    en.wikipedia.org/wiki/Lipoprotein

    A lipoprotein is a biochemical assembly whose primary function is to transport hydrophobic lipid (also known as fat) molecules in water, as in blood plasma or other extracellular fluids. They consist of a triglyceride and cholesterol center, surrounded by a phospholipid outer shell, with the hydrophilic portions oriented outward toward the ...

  7. Biomolecule - Wikipedia

    en.wikipedia.org/wiki/Biomolecule

    Lipids (oleaginous) are chiefly fatty acid esters, and are the basic building blocks of biological membranes. Another biological role is energy storage (e.g., triglycerides). Most lipids consist of a polar or hydrophilic head (typically glycerol) and one to three non polar or hydrophobic fatty acid tails, and therefore they are amphiphilic.

  8. LIPID MAPS - Wikipedia

    en.wikipedia.org/wiki/LIPID_MAPS

    LIPID MAPS was founded in 2003 with NIH funding. [14] LIPID MAPS was previously funded by a multi-institutional grant from Wellcome, and is now funded under an MRC Partnership award, held jointly by University of Cardiff led by Prof Valerie O'Donnell, the Babraham Institute, UCSD and Swansea University, and The University of Edinburgh.

  9. Annular lipid shell - Wikipedia

    en.wikipedia.org/wiki/Annular_lipid_shell

    Annular lipids (also called shell lipids or boundary lipids) are a set of lipids or lipidic molecules which preferentially bind or stick to the surface of membrane proteins in biological cells. They constitute a layer, or an annulus/ shell, of lipids which are partially immobilized due to the existence of lipid-protein interactions.
