| 1 | Purification of a Novel Antibacterial Short Peptide in Earthworm Eisenia foetida显示文摘A novel antimicrobial short peptide was purified from earthworm (Eisenia foetida) by a five-step protocol including ammonium sulfate precipitation, ultrafiltration, DE-52 ion exchange chromatography, Sephadex G-10 column chromatography, and C-18 reversed-phase HPLC techniques. The purified peptide was applied to the MALDI-TOF MS to determine the molecular mass and was also subjected to TOF MS-MS analysis to determine the amino acid sequence. As a result, a novel antibacterial peptide, named OEP3121, was obtained, with the molecular mass of 510.8 Da and the sequence being “ACSAG”. | Yan-QinLIU Zhen-JunSUN ChongWANG Shi-JieLI Yu-ZhiLIU | 2004 | Acta Biochimica et Biophysica Sinica2004，36，4： | 16 |

| 3 | Research on various factors influencing the moisture absorption property of sodium polyacrylate显示文摘Sodium polyacrylate was synthesized with acrylic acid as the monomer, and sodium bisulfate and ammonium persulfate as the initiator, by means of aqueous solution polymerization. The factors influencing the properties of moisture absorption, such as monomer concentration, dosage of initiator, and reaction temperature were systematically investigated. The experimental results indicate that the moisture-absorbing property of this polymer was better than other traditional material, such as silica gel, and molecular sieve. The best reaction condition and formula are based on the orthogonal experiment design. The optimum moisture absorbency of sodium polyacrylate reaches 1.01 g/g. The mathematical correlation of this polymer with various factors and moisture absorbency is obtained based on the multiple regression analysis. The moisture content intuitive analysis table shows that neutralization degree has the most significant influence on moisture absorbency, followed by monomer concentration and reaction temperature, while other factors have less influence. | ZHANG ChunXiao ZHANG WanXi PAN ZhenYuan ZHANG XiYao LIU Jian YUE ChongWang | 2009 | Science China Chemistry2009，52，7： | 1 |
