TL;DR: Intraperitoneal administration of galactosamine to rats results in reversible liver cell injury that is related to a dose‐dependent depletion of uridine phosphates by formation of UDP‐sugar derivatives, and the hepatic carbohydrate metabolism was greatly altered to maintain plasma glucose concentration.

TL;DR: Results indicate that a novel isozyme, which is related to other 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase isozymes, is expressed specifically in neural tissues.

TL;DR: Fru-2,6-P2 increases slightly from day 16 of gestation, reaching a maximum 24 h after birth, remaining quite constant during postnatal development, compared with 6-phosphofructo-1-kinase, which increases progressively after the first week of age, which remains unaltered throughout the period studied.

TL;DR: An HPLC method to quantify hexosamine phosphates in biological samples is described, modified from the o-phthaldialdehyde amino acid analysis procedure, which is more selective and sensitive than previous enzymatic analyses of hexosamines phosphorylation.
