When a protein is folded into its correct shape, it is said to be in its native state. The native state can include one or a small number of conformations that are involved in the natural functioning of the protein. When a protein is unfolded, so that it is no longer in its native state, we say that it is denatured. Experimentally, we can expose proteins to denaturing agents, such as heat, changes in pH, or exposure to certain chemicals. Denaturing agents destabilize the protein s higher-order structure (i.e., quaternary, tertiary, and/or secondary structure) causing the polypeptide chain to unfold. Frying an egg makes the clear part of the egg become hard and white, because the protein in the egg white, albumen, becomes denatured. Frying an egg is irreversible, because the peptide chains from neighboring albumen molecules become entangled in one another. However, under carefully controlled experimental conditions, it is possible to avoid entangling of the denatured chains (e.g., by keeping the protein concentration low and using a gentle chemical denaturing agent). In such a case denaturing is reversible. We can remove the denaturing agent and allow the protein to fold back into its native state. In this way we can experimentally reproduce the folding and unfolding of a protein in order to study the physics of protein folding. Protein folding is, for the most part, an example of self-assembly. Self assembly means that the forces driving the molecules to assemble in the appropriate configuration or quaternary structure are inherent in the molecules themselves, and in their interactions with solvent molecules (such as water and small ions in solution). Only molecules that are part of the final structure are involved. Solvent molecules such as water and small ions in solution are part of the final structure in that they remain associated with the folded protein (or other self-assembled structure) forming hydrogen bonds and other interactions that contribute to stabilizing the structure. Not all protein folding is self-assembly. Many proteins do require assistance from other molecules, called folding moderators or chaperones, in order to achieve their native state. In some cases the folding moderators (often proteins themselves) catalyze a step in the folding process that would otherwise occur very slowly. In other cases a folding moderator may temporarily bind to the peptide chain and bring certain parts of the molecule closer together or may provide a sequestered environment that fosters the protein s native state. Proteins are polymers of amino acids. There are 20 major amino acids commonly found in proteins. Other amino acids are also found in proteins (many of which are slight variations of the major 20), but these 20 are by far the most common. Table 9-1 lists the 20 major amino acids and some of their properties.

Choose the menu item or press the button on your camera that enables continuous or burst shooting mode. Switch to continuous focus mode, if your camera is so equipped. Press the shutter button halfway to focus on the subject. Press the shutter button fully, and hold it down to create a sequence of images, as shown in Figure 5-3. To capture the essence of speed, a slow shutter speed was selected, and the camera was panned with the cyclist, which created the blurry background.

The output is shown here:

string[] strs = { "one", "two", "Three"}; if(IsIn("two", strs)) Console.WriteLine("two is found."); if(IsIn("five", strs)) Console.WriteLine("This won t display.");

To get a web page from your cloud provider, you ll likely be using the Hypertext Transfer Protocol (HTTP) as the computing mechanism to transfer data between the cloud and your organization. HTTP is a stateless protocol. This is beneficial because hosts do not need to retain information about users between requests, but this forces web developers to use alternative methods for maintaining users states. For example, when a host needs to customize the content of a web site for a user, the web application must be written to track the user s progress from page to page. The most common method for solving this problem is sending and receiving cookies.

interface constraint, the type argument must be either the interface or a type that implements that interface. The interface constraint uses this form of the where clause: where T : interface-name Here, T is the name of the type parameter, and interface-name is the name of the interface. More than one interface can be specified by using a comma-separated list. If a constraint includes both a base class and interface, then the base class must be listed first. The following program illustrates the interface constraint:
