Application

Glycerol kinase (glpK) was used to study the effects of pain controlling neuropeptides on human fat cell lipolysis.
Glycerol kinase has been used along with adenosine triphosphate (ATP) for the conversion of glycerol to glycerol-3 phosphate (glycerol-3P) in white adipose tissue (WAT) adipocyte samples by label distribution method. It has also been used along with adenosine triphosphate (ATP) in the derivatization of glycerol to sn-glycerol-3 phosphate (glycerol-3P).

Actions biochimiques/physiologiques

Glycerol kinase catalyzes tge MgATP-dependent phosphorylation of glycerol to produce sn-glycerol-3-phosphate and is the rate limiting enzyme in the utilization of glycerol. It is also subject to feedback regulation by fructose-1,6-bisphosphate.

Définition de l'unité

One unit will convert 1.0 μmole of glycerol and ATP to L-α-glycerophosphate and ADP per min at pH 9.8 at 25 °C in a coupled system with PK/LDH.

Forme physique

Suspension in 3.1 M (NH4)2SO4 pH 7.3, with 1% BSA and 2% trehalose

White adipose tissue (WAT) produces large amounts of lactate and glycerol from glucose. We used mature epididymal adipocytes to analyse the relative importance of glycolytic versus lipogenic glycerol in adipocytes devoid of external stimuli. Cells were incubated (24/48 h) with 7/14 mM

Neuropeptides NPFF and NPSF are involved in pain control, acting through the G-protein coupled receptors (GPR)74 (high affinity for NPFF) and GPR147 (equal affinity for NPFF and NPSF). GPR74 also inhibits catecholamine-induced adipocyte lipolysis and regulates fat mass in humans.

White adipose tissue can metabolize large amounts of glucose to glycerol and lactate. We quantitatively traced glucose label to lactate, glycerol and fats in primary cultures of mature rat epididymal adipocytes. Cells were incubated with 7/14 mM 14C-glucose for 24/48 h. Medium

Recently, we reported on a new class of naphthoquinone derivatives showing a promising anti-trypanosomatid profile in cell-based experiments. The lead of this series (B6, 2-phenoxy-1,4-naphthoquinone) showed an ED(50) of 80 nM against Trypanosoma brucei rhodesiense, and a selectivity index of
