Relative quantification of Leg1 and Leg2 in chickpea chymotryptic hydrolysates by ultrahigh performance-tandem mass spectrometry in scheduled multiple reaction monitoring mode (UHPLC–MS/MS-sMRM). The analytical parameters of the method are displayed. QILQWQ was used as internal standard. The net charge is given by superscript numbers (1+,2+,3+,4+).
