I have created most of the images found in BC Online, using programs such as Power Point, Paint Shop Pro, and ChemDraw. Some of these figures have been modeled after those found in various biochemistry textbooks. I have also used other figures which are already available on the web. I have referenced those by including the url for the site directly on the figure.
Some of the figures in this web book are used by permission from the journal (Science, Nature, and the Proceedings of the National Academy of Science) and in some cases also from the author of those figures. The specific reference for each figure is shown on the figure. For these specific figures:
