Research data no. 1 for the manuscript: Ovalbumin interaction with polystyrene and polyethylene terephthalate microplastics alters its structural properties

Data used for the analysis of pepsin interaction with polystyrene microplastic of 10 and 100 µm in size. Binding isotherms data were used for the construction of binding isotherms from which binding between pepsin and polystyrene microplastic was described. Structural features of pepsin in the presence of polystyrene were analysed by CD spectrometry and spectrofluorimetry.
