Fourteen cholinium-amino acid based room temperature ionic liquids were prepared using a cleaner synthetic method. Chemicophysical properties were well correlated with the wide range of amino acid chemical structures.

A series of room temperature ionic liquids (ILs), in which cholinium acts as the cation and amino acids as the anions, were prepared via a simple and green chemical route, and characterized. Most of the ILs dissolved lignin efficiently and selectively (with solubilities of 140–220 mg of lignin per g of IL). The solubility of xylan in these ILs (which ranged from <1 to 85 mg g−1) depended on the nature of the anion, while cellulose was scarcely soluble (<5 mg g−1). In addition, enzymatic hydrolysis of microcrystalline cellulose and rice straw was enhanced significantly after pretreatment using the IL [Ch][Gly].
of various cations was also investigated. Cellulose was only dissolved in EMIM salts of amino acids. In particular, the influence of the cation type on selected physicochemical and spectroscopic properties were discussed. The article is a mini review on amino acid ionic liquids.

Disclosed herein are methods for reprogramming a somatic cell into a pluripotent stem cell by contacting the somatic cell with one or more antifolate agents, with or without methionine, in vitro for a period of time sufficient to reprogramming the somatic cell and selecting and growing the cells that express one or more stem cell markers. Also disclosed are induced pluripotent stem cells obtained from somatic cells.
