  2. Glycosidic bond - Wikipedia

    en.wikipedia.org/wiki/Glycosidic_bond

    Glycosidic bonds of the form discussed above are known as O-glycosidic bonds, in reference to the glycosidic oxygen that links the glycoside to the aglycone or reducing end sugar. In analogy, one also considers S-glycosidic bonds (which form thioglycosides ), where the oxygen of the glycosidic bond is replaced with a sulfur atom.

  3. Glycoside - Wikipedia

    en.wikipedia.org/wiki/Glycoside

    Salicin, a glycoside related to aspirin Chemical structure of oleandrin, a cardiac glycoside. In chemistry, a glycoside / ˈ ɡ l aɪ k ə s aɪ d / is a molecule in which a sugar is bound to another functional group via a glycosidic bond.

  4. Glycosynthase - Wikipedia

    en.wikipedia.org/wiki/Glycosynthase

    This can result in different regioselectivity depending on the acceptor resulting in products with different glycosidic linkages. One example is the Agrobacterium sp. β-glucosynthase, which forms a β-1,4-glycoside with glucose as the acceptor, but forms a β-1,3-glycoside with xylose as the acceptor.

  5. Carbohydrate synthesis - Wikipedia

    en.wikipedia.org/wiki/Carbohydrate_synthesis

    The glycosidic bond is formed from a glycosyl donor and a glycosyl acceptor. There are four types of glycosidic linkages: 1, 2-trans-α, 1, 2-trans-beta, 1, 2-cis-α, and 1, 2-cis-beta linkages. 1, 2-trans glycosidic linkages can be easily achieved by using 2-O-acylated glycosyl donors (neighboring group participation).

  6. Glycobiology - Wikipedia

    en.wikipedia.org/wiki/Glycobiology

    Defined in the narrowest sense, glycobiology is the study of the structure, biosynthesis, and biology of saccharides (sugar chains or glycans) that are widely distributed in nature. [ 1 ] [ 2 ] Sugars or saccharides are essential components of all living things and aspects of the various roles they play in biology are researched in various ...

  7. Glycolipid - Wikipedia

    en.wikipedia.org/wiki/Glycolipid

    Glycolipid. Glycolipids are lipids with a carbohydrate attached by a glycosidic (covalent) bond. [1] Their role is to maintain the stability of the cell membrane and to facilitate cellular recognition, which is crucial to the immune response and in the connections that allow cells to connect to one another to form tissues. [2]

  8. Lysozyme - Wikipedia

    en.wikipedia.org/wiki/Lysozyme

    In this stressed state, the glycosidic bond is more easily broken. [13] An ionic intermediate containing an oxo-carbenium is created as a result of the glycosidic bond breaking. [ 14 ] Thus distortion causing the substrate molecule to adopt a strained conformation similar to that of the transition state will lower the energy barrier of the ...

  9. Disaccharide - Wikipedia

    en.wikipedia.org/wiki/Disaccharide

    The glycosidic bond can be formed between any hydroxy group on the component monosaccharide. So, even if both component sugars are the same (e.g., glucose), different bond combinations (regiochemistry) and stereochemistry ( alpha- or beta- ) result in disaccharides that are diastereoisomers with different chemical and physical properties.
