  2. Lipolysis - Wikipedia

    en.wikipedia.org/wiki/Lipolysis

    In the body, stores of fat are referred to as adipose tissue. In these areas, intracellular triglycerides are stored in cytoplasmic lipid droplets. When lipase enzymes are phosphorylated, they can access lipid droplets and through multiple steps of hydrolysis, breakdown triglycerides into fatty acids and glycerol. Each step of hydrolysis leads ...

  3. Lipid metabolism - Wikipedia

    en.wikipedia.org/wiki/Lipid_metabolism

    The second step in lipid metabolism is absorption of fats. Short chain fatty acids can be absorbed in the stomach, while most absorption of fats occurs only in the small intestines. Once the triglycerides are broken down into individual fatty acids and glycerols, along with cholesterol, they will aggregate into structures called micelles. Fatty ...

  4. Fatty acid metabolism - Wikipedia

    en.wikipedia.org/wiki/Fatty_acid_metabolism

    Once freed from glycerol, the free fatty acids enter the blood, which transports them, attached to plasma albumin, throughout the body. [4] Long-chain free fatty acids enter metabolizing cells (i.e. most living cells in the body except red blood cells and neurons in the central nervous system) through specific transport proteins, such as the ...

  5. Ketogenesis - Wikipedia

    en.wikipedia.org/wiki/Ketogenesis

    Ketogenesis is the biochemical process through which organisms produce ketone bodies by breaking down fatty acids and ketogenic amino acids. [ 1 ] [ 2 ] The process supplies energy to certain organs, particularly the brain , heart and skeletal muscle , under specific scenarios including fasting , caloric restriction , sleep, [ 3 ] or others.

  6. Fatty acid degradation - Wikipedia

    en.wikipedia.org/wiki/Fatty_acid_degradation

    Fatty acid degradation is the process in which fatty acids are broken down into their metabolites, in the end generating acetyl-CoA, the entry molecule for the citric acid cycle, the main energy supply of living organisms, including bacteria and animals. [1] [2] It includes three major steps: Lipolysis of and release from adipose tissue

  7. Lipase - Wikipedia

    en.wikipedia.org/wiki/Lipase

    Human pancreatic lipase (HPL) is the main enzyme that breaks down dietary fats in the human digestive system. [5] To exhibit optimal enzyme activity in the gut lumen, PL requires another protein, colipase, which is also secreted by the pancreas. [18] lysosomal lipase: LIPA: interior space of organelle: lysosome

  8. Starvation response - Wikipedia

    en.wikipedia.org/wiki/Starvation_response

    Starvation response in animals (including humans) is a set of adaptive biochemical and physiological changes, triggered by lack of food or extreme weight loss, in which the body seeks to conserve energy by reducing metabolic rate and/or non-resting energy expenditure to prolong survival and preserve body fat and lean mass.

  9. Chemical process of decomposition - Wikipedia

    en.wikipedia.org/wiki/Chemical_process_of...

    The human body is composed of approximately: 64% water, 20% protein, 10% fat, 1% carbohydrate, 5% minerals. [1] The decomposition of soft tissue is characterized by the breakdown of these macromolecules, and thus a large proportion of the decomposition products should reflect the amount of protein and fat content initially present in the body.
