Recent Studies from Nankai University Add New Data to Sulfur Amino Acids

May 27, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Researchers detail new data in Sulfur Amino Acids. According to news reporting out of Tianjin, People's Republic of China, by NewsRx editors, research stated, "Two nano-material-containing azo groups have been designed and developed, and the binding ability of nano-materials with various amino acids has been characterized by UV-vis and fluorescence titrations. Results indicated that two nano-materials showed the strongest binding ability for homocysteine among twenty normal kinds of amino acids (alanine, valine, leucine, isoleucine, methionine, aspartic acid, glutamic acid, arginine, glycine, serine, threonine, asparagine, phenylalanine, histidine, tryptophan, proline, lysine, glutamine, tyrosine and homocysteine)."

Our news journalists obtained a quote from the research from Nankai University, "The reason for the high sensitivity for homocysteine was that two nano-materials containing an aldehyde group reacted with -SH in homocysteine and afforded very stable thiazolidine derivatives. Theoretical investigation further illustrated the possible binding mode in host-guest interaction and the roles of molecular frontier orbitals in molecular interplay."

According to the news editors, the research concluded: "Thus, the two nano-materials can be used as optical sensors for the detection of homocysteine."
