Provides flexible strength to our skin, tendons, and internal organs,Īnd underlying structure for bones and teeth. Strands twisted together, collagen is strong, yet flexible. Collagen isĪ relatively simple protein, made of three separate chains of aminoĪcids that twist together.
several polysaccharides, such as cellulose and glycogen.Their most famous functions are those of energy storage and providing cellular structure. Carbohyrates range from simple sugars to complex assemblies of sugars, and have diverse functions. The antigen bound to this antibody is a small protein, lysozymeĬomposed entirely of carbon, hydrogen, and oxygen, carbohydrates are literally hydrated carbon, as seen by their generalized formula, C x(H 2O) y.The "business end" is the part of an antibody thatīinds to a foreign molecule (antigen) to alert the immune system.
Making it easier to show the different protein chains that make This is a partially idealized (computer modeled) structure,.View a model of a complete human antibody.Note: Includes some very advanced material on antibodies Shows the domain structure of IgG, and details of the interactions with an antigen (lysozyme), and more.Includes introductions to molecular displays for amino acids,.Severe infections, and are treated by injecting antibodies from People who lack antibodies get recurrent, Microbes marked with bound antibodies are Recognize and bind very specifically to foreign molecules, suchĪs toxins or parts of invading microbes. Secreted by specialized cells called B lymphocytes. Antibodies, also called immunoglobulins, are soluble proteins Mounted by the immune systems of vertebrates to an unwelcome molecular PLEASE tell us if you use BME3D for teaching!Īntibody production is one part of a complex response All Biomodel resources authored by Angel Herráez unless otherwise noted.

To access more functions, click on the Jmol logo in the corner of the structure area for a pop-up menu.Īll 3d resources open in a new window. Use buttons and controls next to or below the molecule to change the display. To identify an atom, let the mouse cursor rest on top of it for a few seconds. To zoom in or out, use your scroll wheel, or SHIFT-drag with the mouse. To rotate a molecule in the 3d display, click and drag on it with the mouse. Each molecule is descibed briefly in a summary, which is followed by links to the 3d displays, bullet points of features of each display, and finally links to background information for lesson planning purposes. This table draws together the 3d resources with background information for your convenience.
