  2. Lipid - Wikipedia

    en.wikipedia.org/wiki/Lipid

    In an aqueous system, the polar heads of lipids align towards the polar, aqueous environment, while the hydrophobic tails minimize their contact with water and tend to cluster together, forming a vesicle; depending on the concentration of the lipid, this biophysical interaction may result in the formation of micelles, liposomes, or lipid bilayers.

  3. 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.

  4. 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]

  5. Nutrition - Wikipedia

    en.wikipedia.org/wiki/Nutrition

    Nutrition is the biochemical and physiological process by which an organism uses food to support its life. It provides organisms with nutrients , which can be metabolized to create energy and chemical structures.

  6. Biochemistry - Wikipedia

    en.wikipedia.org/wiki/Biochemistry

    Lipids are usually made from one molecule of glycerol combined with other molecules. In triglycerides , the main group of bulk lipids, there is one molecule of glycerol and three fatty acids . Fatty acids are considered the monomer in that case, and may be saturated (no double bonds in the carbon chain) or unsaturated (one or more double bonds ...

  7. Macromolecule - Wikipedia

    en.wikipedia.org/wiki/Macromolecule

    Many macromolecules are polymers of smaller molecules called monomers. The most common macromolecules in biochemistry are biopolymers (nucleic acids, proteins, and carbohydrates) and large non-polymeric molecules such as lipids, nanogels and macrocycles. [1]

  8. Catabolism - Wikipedia

    en.wikipedia.org/wiki/Catabolism

    Catabolism breaks down large molecules (such as polysaccharides, lipids, nucleic acids, and proteins) into smaller units (such as monosaccharides, fatty acids, nucleotides, and amino acids, respectively). Catabolism is the breaking-down aspect of metabolism, whereas anabolism is the building-up aspect.

  9. Biopolymer - Wikipedia

    en.wikipedia.org/wiki/Biopolymer

    Like other polymers, biopolymers consist of monomeric units that are covalently bonded in chains to form larger molecules. There are three main classes of biopolymers, classified according to the monomers used and the structure of the biopolymer formed: polynucleotides, polypeptides, and polysaccharides.
