Theoretical Molecular Biophysics

"Theoretical Molecular Biophysics" is a sophisticated research e-book for college students, almost immediately sooner than or after finishing undergraduate reports, in physics, chemistry or biology. It offers the instruments for an figuring out of user-friendly techniques in biology, resembling photosynthesis on a molecular point. A simple wisdom in mechanics, electrostatics, quantum conception and statistical physics is fascinating.

Mathematical Theory of Electrophoresis

The improvement of latest molecular biology with its growing to be tendency towards in-depth research of the mechanisms of organic tactics, constitution, functionality, and identity of biopolymers calls for program of exact physicochemical tools. Electrophoresis occupies a key place between such equipment.

This machine permits the detection of small and medium size peptides/proteins and even permits their specific identification. There are several machine strategies, but all work by ionizing proteins and forcing them to move through an electric field in a way that permits selection and detection of different protein molecular weights. The best mass spectrometer (MS) machines not only detect proteins by their individual molecular weights but also are able to put selected proteins through a fragmentation process that in principle generates a series of amino acid sequences that are characterized by their molecular weights.

The first technique generates transgenic animals, animals that from birth contain a gene of another species. The new gene is inserted into the genome of a fertilized egg and the eggs are implanted into a foster mother. Offspring are tested for the new gene and positive animals are bred to establish a new strain. Examples of this technology are the production of human proteins and human antibodies in cattle and the generation of green mice, transgenic mice that contain a green fluorescent protein originally found in jellyfish.

As the excitement in genomics converts into routine identifications of problem genes, a new frontier, called proteomics has emerged (24). Proteomics is the study of the entire pool of protein, the proteome, that a cell or organism makes. Proteomics is a more complicated science than genomics and lags further behind it because the biochemical rules for protein folding and protein interactions are less well worked out than for DNA and RNA. In fact, although there are super computers and numerous groups working on this problem, it is still impossible to take a string of amino acids and predict how it will fold in solution and how effectively it will interact with the other protein surfaces it must interact with and recognize.
