Study Findings from National Cheng Kung University Broaden Understanding of Essential Amino Acids

June 13, 2014



By a News Reporter-Staff News Editor at Science Letter -- Current study results on Essential Amino Acids have been published. According to news reporting originating in Tainan, Taiwan, by NewsRx journalists, research stated, "The preparation of alkyl chain-grafted poly(L-lysine) (PLL) vesicles with tunable molecular assembly in aqueous solution and the evaluation of their membrane permeability by drug release experiments have been investigated."

The news reporters obtained a quote from the research from National Cheng Kung University, "Upon grafting long alkyl chains, polypeptides confined in the assembled nanostructures adopted ordered conformations such as alpha-helices or beta-sheets/turns, leading to the dense packing of membranes and, consequently, the decreases in vesicular size and membrane permeability. The vesicles can also be cross-linked by genipin to form stable structures with tunable membrane permeability."

According to the news reporters, the research concluded: "Additionally, these vesicles exhibited noticeable pH-sensitive behavior, depending on the grafted alkyl chain and cross-linking."
