  2. Glucose transporter - Wikipedia

    en.wikipedia.org/wiki/Glucose_transporter

    structure summary. Glucose. Glucose transporters are a wide group of membrane proteins that facilitate the transport of glucose across the plasma membrane, a process known as facilitated diffusion. Because glucose is a vital source of energy for all life, these transporters are present in all phyla.

  3. Glycolysis - Wikipedia

    en.wikipedia.org/wiki/Glycolysis

    d -Glucose + 2 [NAD] + + 2 [ADP] + 2 [P] i 2 × Pyruvate 2 × + 2 [NADH] + 2 H + + 2 [ATP] + 2 H 2 O Glycolysis pathway overview The use of symbols in this equation makes it appear unbalanced with respect to oxygen atoms, hydrogen atoms, and charges. Atom balance is maintained by the two phosphate (P i) groups: Each exists in the form of a hydrogen phosphate anion, dissociating to contribute ...

  4. Glycal - Wikipedia

    en.wikipedia.org/wiki/Glycal

    Glycal. Glucal, the glycal formed from glucose. Glycal is a name for cyclic enol ether derivatives of sugars having a double bond between carbon atoms 1 and 2 of the ring. The term "glycal" should not be used for an unsaturated sugar that has a double bond in any position other than between carbon atoms 1 and 2. [1]

  5. Fatty acid synthesis - Wikipedia

    2, to interact with the saturated fatty acyl-CoA chain, forming a double bond and two molecules of water, H 2 O. Two electrons come from NADH + H + and two from the single bond in the fatty acid chain. [7] These mammalian enzymes are, however, incapable of introducing double bonds at carbon atoms beyond C-9 in the fatty acid chain. [nb 1].)

  6. Beta oxidation - Wikipedia

    en.wikipedia.org/wiki/Beta_oxidation

    Beta oxidation. In biochemistry and metabolism, beta oxidation (also β-oxidation) is the catabolic process by which fatty acid molecules are broken down in the cytosol in prokaryotes and in the mitochondria in eukaryotes to generate acetyl-CoA. Acetyl-CoA enters the citric acid cycle, generating NADH and FADH 2, which are electron carriers ...

  7. Sodium-glucose transport proteins - Wikipedia

    en.wikipedia.org/wiki/Sodium-glucose_transport...

    InterPro. Sodium-dependent glucose cotransporters (or sodium-glucose linked transporter, SGLT) are a family of glucose transporter found in the intestinal mucosa (enterocytes) of the small intestine (SGLT1) and the proximal tubule of the nephron (SGLT2 in PCT and SGLT1 in PST). They contribute to renal glucose reabsorption.

  8. O-linked glycosylation - Wikipedia

    en.wikipedia.org/wiki/O-linked_glycosylation

    O-linked glycosylation is the attachment of a sugar molecule to the oxygen atom of serine (Ser) or threonine (Thr) residues in a protein. O-glycosylation is a post-translational modification that occurs after the protein has been synthesised. In eukaryotes, it occurs in the endoplasmic reticulum, Golgi apparatus and occasionally in the ...

  9. Glycosyltransferase - Wikipedia

    en.wikipedia.org/wiki/Glycosyltransferase

    Most glycosyltransferase enzymes form one of two folds: GT-A or GT-B. Glycosyltransferases (GTFs, Gtfs) are enzymes that establish natural glycosidic linkages.They catalyze the transfer of saccharide moieties from an activated nucleotide sugar (also known as the "glycosyl donor") to a nucleophilic glycosyl acceptor molecule, the nucleophile of which can be oxygen- carbon-, nitrogen-, or sulfur ...
