Dr Mustafa Jawad Introduction The proteins of immune system include structural proteins soluble proteins Structural proteins include surface proteins such as MHC system HLA cytokine receptors surface antibodies.

Our Immune System protects us from diseases. 2. Proteins (. Polypeptides. ). Chains of Amino acids (. 20. different kinds). bonded together by . peptide bonds. . (. polypeptides. ). Made of . Nitrogen, Carbon, Oxygen, and Hydrogen. Functions:. B.2. Properties of 2-amino acids . (B.2.2). Zwitterion. (dipolar) . amino acids contain both acidic and basic groups in the same molecule . therefore, are . amphoteric. in nature (capable of behaving as acids or bases). What is structure?. What is function?. The . structure. is the shape of each part of a living thing. . Function. . describes how the part . is used . or how it works.. Velcro, a road reflector, a video game joystick, and a submarine's ballast tanks all have structures inspired by nature.. Ligand. In biochemistry and pharmacology, a ligand is a substance that forms a complex with a biomolecule to serve a biological purpose. In protein-ligand binding, the ligand is usually a molecule which produces a signal by binding to a site on a target protein. The binding typically results in a change of conformation of the target protein.. Introducing proteins. Proteins. are a diverse group of large and complex polymer molecules, made up of long chains of . amino acids. .. They have a wide range of biological roles, including:. structural:. Key attributes of immune system. 4 attributes that characterize the immune system as a whole. specificity. antigen-antibody specificity. diversity. react to millions of antigens. memory. rapid 2° response. By Renira Rugnath and Jeshanah Johnson . Basics . Homeostasis, or a "steady state," is a continual balancing act of the body systems to provide an internal environment that is comparable with life. The two liquid tissues of the body, the blood and lymph have separate but interrelated functions in maintaining this balance. They combine with a third system, the immune, to protect the body against pathogens that could threaten the organism's viability. . Main Function. The Immune System is used to prevent infection and . disease.. Using . a variety of cells and organs, the Immune System disposes of foreign or harmful antibodies through a process known as the immune response.. The specialists who diagnose and treat immune system disorders are called . immunologists. , and the specialty itself is called . immunology. .. Phagocytes. Phagocytes are often the first immune system cells . HIV. (Human immunodeficiency virus)- a virus that attacks the immune system.. Infection with HIV can be prevented. Responsible decisions is the most valuable tool for protection against HIV.. Example: Abstinence from sexual activity and injecting drugs reduce your risk.. Each amino acid (aa) shares a common structure; i.e. an amine (NH. 2. ) group, an acid group (COOH), and a central carbon atom bonded to hydrogen and to a side chain (R).. The side chains qualify aas as acidic, basic, neutral, aromatic, and sulphur-containing amino acids.. The Immune System. The immune system is a group of cells & soluble molecules, which interact & distinguish patterns in the body as “self” or “non-self,” in order to eliminate those that are “non-self.”.
