Abstract: 3-methoxy-4-hydroxymandelic acid (VMA) was the critical intermediate for the synthesis of vanillin by the glyoxylic acid method. Meanwhile, a valuable byproduct (2-hydroxy-3-methoxy-mandelic acid, o-VMA) was obtained during the reaction. Al3+ was found to be a… read more here.

Abstract: Urinary homovanillic acid (HVA) and vanillylmandelic acid (VMA) are widely used diagnostic markers for neuroblastoma, but urinary markers for risk assessment prior to invasive biopsy are lacking. We hypothesized that cystathionine (CTN) may be a… read more here.
