Jun 21, 2024 · Antibody, a protective protein produced by the immune system in response to the presence of a foreign substance, called an antigen. Antibodies recognize and latch onto antigens in order to remove them from the body. Learn more about the function and structure of antibodies in this article.
The antibody's paratope interacts with the antigen's epitope. An antigen usually contains different epitopes along its surface arranged discontinuously, and dominant epitopes on a given antigen are called determinants. Antibody and antigen interact by spatial complementarity (lock and key).
The article gives a detailed account of antibody including antibody structure, types of antibodies, functions of antibody, and its production. It also explains how an antibody is different from an antigen.
Aug 3, 2023 · They are also known as Immunoglobulins. The use of the term antibody defines an Immunoglobulin molecule that has specificity for an epitope of the molecules that make up antigens.
May 6, 2022 · Antibodies are proteins that protect you when an unwanted substance enters your body. Produced by your immune system, antibodies bind to these unwanted substances in order to eliminate them from your system. Another word for antibody is immunoglobulin.
Aug 11, 2021 · Each antibody is specific and has one of two precise tasks: tag an invader for destruction by other immune cells, or destroy the invader by itself. An antibody can recognize and bind to an...
Apr 22, 2018 · An antibody is a specialized defense protein synthesized by the vertebrate immune system. These small structures are actually made of 4 different protein units. The ends of the molecule are variable, and can be adapted to bind to any molecule.
Jun 21, 2024 · Antibody - Structure, Classes, Function: Each antibody molecule is essentially identical to the antigen receptor of the B cell that produced it. The basic structure of these proteins consists of two pairs of polypeptide chains (lengths of amino acids linked by peptide bonds) that form a flexible Y shape.
Jul 17, 2020 · Antibodies are Y-shaped proteins that bind to the body's foreign invaders and signal the immune system to get to work.(Image credit: Shutterstock) Antibodies are specialized, Y-shaped proteins...
An antibody is a class of protein called an immunoglobulin, which is made by specialised white blood cells to identify and neutralise material foreign to an immune system.
