Efficient conversion of glutamic acid to healthy protein like thiomide with lycopene as catalyst using catalytic transfer sulfurization process

Abstract

This paper describes a simple one-step catalytic transfer sulfurization technique that may be used to synthesize glutamic thiamides with the aid of lycopene. First, lycopene is made from fresh tomatoes using a solvent extraction technique, and it is then utilized to make the glutamic thiomides. Glutamic thiamide particles are characterized by Raman, FTIR, XRD, SEM and EDS. The lycopene acted as a catalyst for sulfurizing of glutamic acid in H₂S atmosphere. According to Image J analysis, the average size of the glutamic thiomide enclosed by lycopene is estimated to be in the range of 30 nm - 10 nm, respectively. When lycopene or H₂S are heated to 100°C for 45 min, lycopene shows 81.9 % catalytic activity in the conversion of glutamic acid to glutamic thiomide, and 89.2% with selectivity. Lycopene alone demonstrates 35.68% catalytic activity in the conversion of glutamic acid to glutamic thiomide with ethanol for the reaction time 15min. Moreover, lycopene-100 is stable and exhibits high catalytic efficiency in the decomposition of glutamic acids using various polar solvents.
