If you can play an mp4, download the video as mp4 here ChemBioOffice is a scientifically intelligent, integrated suite of personal productivity tools that enables scientists and researchers to capture, store, retrieve and share data and information on compounds, reactions, materials and their properties. ChemBioOffice helps chemists and biologists to efficiently keep track of their work, visualize and gain a deeper understanding of their results and correlate biological activity with chemical structures. ChemBioOffice includes the following applications: Figure 1: Personal productivity tools to organize and explore compounds, reactions, materials and associated properties.

PyMOL - Wiki Non-free binaries[edit] On 1 August 2006, DeLano Scientific adopted a controlled-access download system for pre-compiled PyMOL builds (including betas) distributed by the company. Access to these executables is now limited to paying customers but is free for students and teachers. However, the current source code continues to be available at no cost, as are older pre-compiled builds. While the build systems for other platforms are open, the win32 build system is not (although Windows binaries are available online). Non-students and teachers can either compile an executable from the source code or pay for a subscription to the support services to obtain access to pre-compiled executables. Acquisition of PyMOL by Schrödinger[edit] Gallery[edit] Example of some molecular editing features of PyMOL, dihedral bond rotation and interactive molecular relaxation with "Sculpting mode", these are useful features for preparation of input geometry for quantum chemistry software See also[edit]

Database of Periodic Tables There are hundreds of periodic tables in web space, but there is only one comprehensive database of periodic tables & periodic system formulations. If you know of an interesting periodic table that is missing, please contact the database curator: Dr Mark R Leach. Harrington Periodic Tables So we start this effort tabula rasa (without preconceived ideas). 1) All atoms have a default "common denominator" structure at 270 mass units, irrespective of the element under discussion. Top of Page KAS Periodic Table The KAS periodic table reproduces and depicts the nuclear properties of chemical elements. The Segre Chart is based on the number of protons, Z, and the number of neutrons, N. Location that remains near the Neutron Dripline of element. Read more here, here and here.

Bioinformatics Tools for Pairwise Sequence Alignment Pairwise Sequence Alignment is used to identify regions of similarity that may indicate functional, structural and/or evolutionary relationships between two biological sequences (protein or nucleic acid). By contrast, Multiple Sequence Alignment (MSA) is the alignment of three or more biological sequences of similar length. From the output of MSA applications, homology can be inferred and the evolutionary relationship between the sequences studied. Global Alignment Global alignment tools create an end-to-end alignment of the sequences to be aligned. Needle EMBOSS Needle creates an optimal global alignment of two sequences using the Needleman-Wunsch algorithm. Protein Nucleotide Stretcher EMBOSS Stretcher uses a modification of the Needleman-Wunsch algorithm that allows larger sequences to be globally aligned. Protein Nucleotide Local Alignment Local alignment tools find one, or more, alignments describing the most similar region(s) within the sequences to be aligned. Water Protein Nucleotide

Chemistry Freeware On this page I post reviews and links to freeware chemistry programs available for download at other sites around the internet. All of the programs are ones that I have used, or currently use. None-the-less, I take no responsiblity for any problems you might experience as a result of installing any of these applications. Unless otherwise noted, the programs are for Windows systems. ACD/ChemSketch 12 Freeware. ACD continues to release updates to the outstanding Chemsketch freeware. MolView.Org is a web-based molecular viewing and modeling tool. Discovery Studio Visualizer 4. ChemAxon produces a wide range of Java-based chemistry tools, and they offer free academic licenses (you must register with them). The Virtual Laboratory from the ChemCollective is a personal favorite. KnowItAll Academic Edition - In a continued commitment to academia, Bio-Rad is offering this completely FREE and fully functional software package to promote learning and research in the academic community.

Fatty Acids Types of fatty acids[edit] Three-dimensional representations of several fatty acids Fatty acids that have carbon–carbon double bonds are known as unsaturated. Fatty acids without double bonds are known as saturated. They differ in length as well. Length of free fatty acid chains[edit] Fatty acid chains differ by length, often categorized as short to very long. Short-chain fatty acids (SCFA) are fatty acids with aliphatic tails of fewer than six carbons (i.e. butyric acid).[4]Medium-chain fatty acids (MCFA) are fatty acids with aliphatic tails of 6–12[5] carbons, which can form medium-chain triglycerides.Long-chain fatty acids (LCFA) are fatty acids with aliphatic tails 13 to 21 carbons.[6]Very long chain fatty acids (VLCFA) are fatty acids with aliphatic tails longer than 22 carbons Unsaturated fatty acids[edit] Unsaturated fatty acids have one or more double bonds between carbon atoms. cis A cis configuration means that adjacent hydrogen atoms are on the same side of the double bond. trans
