Glucose breakdown in certain mammalian and bacterial cells can occur by mechanisms other than classic glycolysis.  In most of these, glucose 6-phosphate is oxidized to 6-phosphogluconate, which is then further metabolized by:

#XL - S Microbiology
  1. an aldolase-type split to form glyceric acid and glyceraldehyde 3-phosphate.

  2. an aldolase-type split to form glycolic acid and erythrose 4-phosphate.

  3. conversion to 1,6-bisphosphogluconate.

  4. decarboxylation to produce keto- and aldopentoses.
