  2. Lipid metabolism - Wikipedia

    en.wikipedia.org/wiki/Lipid_metabolism

    Since lipids are hydrophobic molecules, they need to be solubilized before their metabolism can begin. Lipid metabolism often begins with hydrolysis, [7] which occurs with the help of various enzymes in the digestive system. [2] Lipid metabolism also occurs in plants, though the processes differ in some ways when compared to animals. [8]

  3. Lipolysis - Wikipedia

    en.wikipedia.org/wiki/Lipolysis

    Lipolysis / l ɪ ˈ p ɒ l ɪ s ɪ s / is the metabolic pathway through which lipid triglycerides are hydrolyzed into a glycerol and free fatty acids. It is used to mobilize stored energy during fasting or exercise, and usually occurs in fat adipocytes.

  4. 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. [34] [35] Cholesterol sulfate reaches its highest concentration in the granular layer of the ...

  5. Fatty acid metabolism - Wikipedia

    en.wikipedia.org/wiki/Fatty_acid_metabolism

    Fatty acid metabolism consists of various metabolic processes involving or closely related to fatty acids, a family of molecules classified within the lipid macronutrient category. These processes can mainly be divided into (1) catabolic processes that generate energy and (2) anabolic processes where they serve as building blocks for other ...

  6. Lipidology - Wikipedia

    en.wikipedia.org/wiki/Lipidology

    The surface of a curved lipid bilayer. Lipidology is the scientific study of lipids. Lipids are a group of biological macromolecules that have a multitude of functions in the body. [1] [2] [3] Clinical studies on lipid metabolism in the body have led to developments in therapeutic lipidology for disorders such as cardiovascular disease. [4]

  7. 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.

  8. Beta oxidation - Wikipedia

    en.wikipedia.org/wiki/Beta_oxidation

    Furthermore, studies indicate that lipid disorders are involved in diverse aspects of tumorigenesis, and fatty acid metabolism makes malignant cells more resistant to a hypoxic environment. Accordingly, cancer cells can display irregular lipid metabolism with regard to both fatty acid synthesis and mitochondrial fatty acid oxidation (FAO) that ...

  9. Fatty acid degradation - Wikipedia

    en.wikipedia.org/wiki/Fatty_acid_degradation

    The products of lipolysis, free fatty acids, are released into the bloodstream and circulate throughout the body. During the breakdown of triacylglycerols into fatty acids, more than 75% of the fatty acids are converted back into triacylglycerol, a natural mechanism to conserve energy, even in cases of starvation and exercise.
