Sulfur is an essential biological element, yet its biochemistry is only partially understood because there are so few tools for studying this element in biological systems. X‐ray absorption spectroscopy provides a unique approach to determining the chemical speciation of sulfur in intact biological samples. Different biologically relevant sulfur compounds show distinctly different sulfur K‐edge X‐ray absorption spectra, and we show here, as an example, that this allows the deconvolution of the sulfur species in equine blood.
