Associate Professor (SSD CHIM/06)


ORGANIC CHEMISTRY I AND LABORATORY (A-L) in the Bachelor's Degree Course in Chemistry.

Main research topics:

  1. Characterization of cereal and milk proteins, in particular for the identification of components with allergenic characteristics (anti-nutritional factors), and of bioactive peptides with nutraceutical properties;
  2. Structural studies of the mitochondrial Voltage-Dependent Anion Selective Channel proteins (VDACs).
  3. Analysis of protein mixtures by means of electrophoretic and chromatographic techniques combined with mass spectrometry.

Rosaria Saletti graduated cum laude in Chemistry at the University of Catania and since 2018 she is Associate Professor of Organic Chemistry.

She has participated to several national and international research programs and has been coordinator of a research unit within the Research Project of National Interest (PRIN) 2006. She has participated to research projects in collaboration with public institutions and pharmaceutical industries.

She is author of over 90 scientific papers on international referred journals, and of about 160 communications at scientific national and international meetings.

She is currently the lecturer of the course of Organic Chemistry I and Laboratory (A-L) in the Bachelor's Degree Course in Chemistry.

She is supervisor of numerous graduate theses in Chemistry, Industrial Chemistry, Organic and Bioorganic Chemistry, Biomolecular Chemistry, and Sanitary and Cell-Molecular Biology. She was tutor of PhD students of the Doctoral School in Chemical Sciences and of the Doctoral School in Neuroscience of the University of Catania, and currently she is tutor of a PhD student of the XXXV cycle (Industrial Doctoral School, within the National Operational Program (PON) FSE-FESR "Research and Innovation 2014-2020" - Action I.1 "Innovative Doctorates with industrial characterization", entitled “Biomarkers in ophthalmology: tissue crosstalk in ocular pathologies”, industrial partner S.I.F.I.

The scientific activity is mainly devoted to the structural characterization of proteins by mass spectrometry and combined electrophoretic and chromatographic techniques (nUHPLC/nESI MSMS).

In particular:

  1. The characterization of the primary structure and post-translational modifications of Voltage-Dependent Anion Selective Channel (VDACs) proteins in different organisms and in a model cell line of Amyotrophic Lateral Sclerosis (ALS), in order to identify possible biomarkers of this neurodegenerative disease useful for its early diagnosis;
  2. The comparative analysis, using proteomic approaches, of the protein fraction of ancient and modern wheat varieties, of unmodified and transgenic cultivars, and of wheat varieties subjected to thermal stress compared to those grown under normal conditions, in order to identify the differentially expressed proteins. The study also concerned the structural characterization of high and low molecular weight glutenin subunits.
  3. Proteomic analysis of milk of various species, including the determination of minority components and post-translational modifications;
  4. The study of the orange flesh proteome;
  5. The structural analysis of bioactive peptides extracted from marine organisms;
  6. The protein characterization of archaeological finds.
