Abstract

Some proteins are soluble in aqueous solutions and some are not. Insoluble proteins can be a problem because the proteins can form large aggregates in solution which are difficult to purify, crystallize, and use in experiments. Compare the amino acid sequence and 3-D structures of some soluble and insoluble proteins (Berman, 2000). Is the structure polar or non-polar, and how might this affect solubility? How do detergents make an insoluble protein more soluble? Investigate how this technology is used to make cleaning products that are designed to break up the biochemical particulate matter that create stains on clothing and other surfaces. Are detergents or special enzymes involved?

Life is all around you in beauty, abundance, and complexity. Biologists are the scientists who study life in all its forms and try to understand fundamental life processes, and how life relates to its environment. They answer basic questions, like how do fireflies create light? Why do grunion fish lay their eggs based on the moon and tides? What genes control deafness? Why don't cancer cells die? How do plants respond to ultraviolet light? Beyond basic research, biologists might also apply their research and create new biotechnology.
