Mass spectra of lipid species in complex biological samples are a challenge to interpret since the lipid composition is specific to organism, tissue and cell. Additionally, thousands of lipid species are present in a biological sample and the number of lipid classes and the isomer are high and diverse. For their accurate identification different measured physicochemical properties, such as accurate mass, fragmentation behaviour and a polarity, have to be considered in the pre-processed data. Here, we present a recently proposed bioinformatics tool i.e. Lipid-Pro (Ahmed et al., 2015a; Ahmed et al., 2015b), a desktop application for the interpretation of LC-MS/MS data. It is a lipid identification solution towards the lipidome analysis, where defined lipid species are identified in the pre-processed data (lipid profiling). The graphical interface of the Lipid-Pro is very simple to install and use. It consists of five main modules: Building Bock, Precursor Candidates, Fragment Candidates, Mass Analyzer and Lipid Identifier. Using these modules, user can define building blocks, compose lipid molecular ions and their fragments, calculate m/z-values of lipid molecular ions and their characteristic fragments, and identify lipid species. Moreover, it also provide comprehensive data management, sharing and integration features. Lipid-Pro is a well-planned scientific solution, implementing the Butterfly paradigm (Ahmed et al., 2014a; Ahmed et al., 2014b). Started with the initialization of the finalized scientific solution’s requirements, then modelled and mocked using HCI guidelines. It is programmed in C# programming language, using Microsoft Dot Net Framework and only compatible to the Microsoft Windows Operating Systems (preferred OS version: 7). The most recent available version of Lipid-Pro has been tested and validated at the Metabolomics Core Unit and Department of Pharmaceutical Biology, University of Wuerzburg Germany. Lipid-Pro is a freely available tool for non-commercial, academic and scientific research, accessible at the following web link: (http://www.neurogenetics.biozentrum.uni-wuerzburg.de/en/project/services/lipidpro/). To have complete application details, please consult publication (Ahmed et al., 2015a).
