Abstract

"This dissertation is divided into two parts. The first part of the research involved an assessment of antioxidant activity of synthetic antioxidants, such as Butylated hydroxytoluene (BHT), santoquin, tocopherols and extracts of naturally occurring materials such as green tea, ginger root, kelp etc. Assessment included the classical active oxygen method (AOM) and gas chromatographic - mass spectrometry determinations of oxidative degradation products...The second part of the research involved enzymatic synthesis and liquid chromatographic - mass spectrometric (LC-MS) characterization of cysteine containing hydrophobic oligopeptides. Two types of oligopeptides L-cysteine homo-oligopeptides and L-cysteine, L-methionine hetero-oligopeptides were synthesized through papain catalyzed oligomerization reactions."--Abstract, page iii.
