  2. 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 ...

  3. Polysaccharide - Wikipedia

    en.wikipedia.org/wiki/Polysaccharide

    Starch (a polymer of glucose) is used as a storage polysaccharide in plants, being found in the form of both amylose and the branched amylopectin. In animals, the structurally similar glucose polymer is the more densely branched glycogen, sometimes called "animal starch". Glycogen's properties allow it to be metabolized more quickly, which ...

  4. Glycosidic bond - Wikipedia

    en.wikipedia.org/wiki/Glycosidic_bond

    DNA molecules contain 5-membered carbon rings called deoxyriboses that are directly attached to two phosphate groups and a nucleobase that contains amino groups. The nitrogen atoms from the amino group in the nucleotides are covalently linked to the anomeric carbon of the ribose sugar structure through an N-glycosidic bond. Occasionally, the ...

  5. Enzyme - Wikipedia

    en.wikipedia.org/wiki/Enzyme

    An enzyme together with the cofactor(s) required for activity is called a holoenzyme (or haloenzyme). The term holoenzyme can also be applied to enzymes that contain multiple protein subunits, such as the DNA polymerases; here the holoenzyme is the complete complex containing all the subunits needed for activity.

  6. Glucose - Wikipedia

    en.wikipedia.org/wiki/Glucose

    The enzymes that join glucose to other molecules usually use phosphorylated glucose to power the formation of the new bond by coupling it with the breaking of the glucose-phosphate bond. Other than its direct use as a monomer, glucose can be broken down to synthesize a wide variety of other biomolecules.

  7. α-Amylase - Wikipedia

    en.wikipedia.org/wiki/Α-Amylase

    Endohydrolysis of (1→4)-α-D-glucosidic linkages in polysaccharides containing three or more (1→4)-α-linked D-glucose units. It is the major form of amylase found in humans and other mammals. [3] It is also present in seeds containing starch as a food reserve, and is secreted by many fungi. It is a member of glycoside hydrolase family 13.

  8. Amylopectin - Wikipedia

    en.wikipedia.org/wiki/Amylopectin

    The synthesis of amylopectin depends on the combined efforts of four different enzymes. These four different enzymes are: [16] [19] [21] ADP glucose pyrophosphorylase (AGPase) soluble starch synthase (SS) starch branching enzyme (BE) starch debranching enzyme (DBE) Amylopectin is synthesized by the linkage of α(1→4) Glycosidic bonds.

  9. Pyruvate decarboxylation - Wikipedia

    en.wikipedia.org/wiki/Pyruvate_decarboxylation

    Because of this, the link reaction occurs twice for each glucose molecule to produce a total of 2 acetyl-CoA molecules, which can then enter the Krebs cycle. Energy-generating ions and molecules , such as amino acids and carbohydrates , enter the Krebs cycle as acetyl coenzyme A and oxidize in the cycle. [ 5 ]
