D glyceraldehyde

D,L-glyceraldehyde-3-phosphate was purchased from Santa Cruz Biotechnology, Inc. D-glyceraldehyde (GA) and other reagents were purchased from Sigma-Aldrich.

Bovine serum albumin (BSA) (essentially fatty acid free and essentially globulin free, lyophilized powder) and D-glyceraldehyde were purchased from Sigma (St. Louis, MO, USA). Ethyl acetate and n-butanol were purchased from Wako Pure Chemical Industries, Ltd. (Osaka, Japan).

Cell lines were maintained in DMEM (Thermo Fisher Scientific Waltham, MA, USA) medium, without glucose, glutamine, phenol red, and sodium pyruvate. The media were supplemented with 10% fetal bovine serum (Thermo Fisher Scientific Waltham, MA, USA), 2 mM glutamine (Thermo Fisher Scientific Waltham, MA, USA), and 2.5 g/L glucose (Merck, Darmstadt, Germany) and cultivated at $37 °\mathrm{C}$ , 5% CO₂, 21% O₂ and 85% relative humidity. To avoid contact inhibition, cells were passaged every 3–4 days. The neuroblastoma cell lines BE(2)-C (RRID: CVCL_0529) were obtained from ECACC (Salisbury, UK). The IMR-32 (RRID: CV CL_0346), GI-ME-N (RRID: CVCL_1232) and SH-SY5Y (RRID: CVCL_0019) cell lines were purchased from the DSMZ (Braunschweig, Germany). Cell lines were authenticated via the Multiplex human Cell line Authentication Test (Multiplexion, Immenstaad, Germany). The active primary human foreskin fibroblasts from an infant donor (VH7) were a gift from Petra Boukamp (German Cancer Research Center (DKFZ), Heidelberg, Germany). L-glyceraldehyde (73572, Sigma-Aldrich, St. Louis, MO, USA), D-glyceraldehyde (49800, Sigma-Aldrich, St. Louis, MO, USA) were prepared in 1M stock solutions in PBS and stored at 4% before use. N-acetyl-cysteine (A9165, Sigma-Aldrich, St. Louis, MO, USA) was prepared in a 500 mM solution in PBS fresh before use in cell culture.
