The University of Minnesota Biocatalysis/Biodegradation Database (UM/BBD) contains "microbial biocatalytic reactions and biodegradation pathways primarily for xenobiotic, chemical compounds." A new microbial enzyme-catalyzed reactions has been posted for 2,4-Dichlorophenoxyacetic Acid. 2,4-dichlorophenoxyacetic acid (2,4-D) is used in cultivated agricultural areas, rangeland and pastures,...

The National Oceanic and Atmospheric Administration's (NOAA) Office of Response and Restoration has created the Chemical Reactivity Worksheet to help teachers, students, and the general public learn about the chemical reactivity of thousands of common hazardous chemicals. After downloading a free program, visitors will find that the datasheets contain information about the hazards of a number of...

Before becoming an author, Jeremy Schneider was a chemistry teacher. Over the past several years he has placed a number of helpful instructional resources here on his site. These particular resources cover atomic structure, quantum mechanics, atomic size, bonding, and several dozen additional topics. Visitors can browse through these resources at their leisure and each topic area includes a brief...

The University of Minnesota Biocatalysis/Biodegradation Database (UM/BBD) contains "microbial biocatalytic reactions and biodegradation pathways primarily for xenobiotic, chemical compounds." A new microbial enzyme-catalyzed reactions has been posted for Flourene. Flourene is commonly found in vehicle exhaust emissions, motor oils, crude oils, coal and oil combustion products, industrial...

This Web site addresses Professor Dr. J. Gmehling's research group activities in "the synthesis and design of chemical processes with an emphasis on thermal separation processes." Ranging from the development of thermodynamic models to the construction of software tools and data banks, their research at the University of Oldenburg, covers a broad range in the field of Industrial Chemistry....

The Institute for Chemical Research at Kyoto University provides this frequently updated and well-documented database of enzyme reactions. With more than 9,300 entries, the LIGAND Chemical Database includes over 3,700 entries for enzymes (the Enzyme Reaction Database) and 5,600 entries for compounds (Chemical Compound Database). The database is searchable by keyword using DBGET (which supports...

The University of Minnesota Biocatalysis/Biodegradation Database (UM/BBD) contains "microbial biocatalytic reactions and biodegradation pathways primarily for xenobiotic, chemical compounds." A new microbial enzyme-catalyzed reactions has been posted for Organomercury. The Organomercury pathway map highlights mercury, a highly toxic heavy metal used "as a pesticide, herbicide, fungicide,...

Scientists Huan-Xiang Zhou, Stanislaw Wlodek, and Andrew McCammon created this animation showing "the 'breathing' motions of the gorge or channel that leads from the region outside the enzyme Acetylcholinesterase (AChE), to the active site." The enzyme AChE controls the communication among nerve and muscle cells. This animation demonstrates, for the first time, the role of molecular dynamics in...

Dr. Thomas Chasteen at Sam Houston State University created this compilation of sites and texts related to chemiluminescence, a process where "energy in the form of light is released from matter because of a chemical reaction." The site contains Quick Time animations, descriptions of related phenomena, links to related sites, and two bibliographies, one targeting advanced readers and the other...
