difference between antibodies &  antibiotics.

 Antibodies-It is also known as an immunoglobulin, is a large Y-shaped protein produced by B-cells that is used by the immune system to identify and neutralize foreign objects such as bacteria and viruses. The antibody recognizes a unique part of the foreign target, called an antigen.Each tip of the Y of an antibody contains a paratope that is specific for one particular epitope  on an antigen, allowing these two structures to bind together with precision. Using this binding mechanism, an antibody can tag a microbe or an infected cell for attack by other parts of the immune system, or can neutralize its target directly. The production of antibodies is the main function of the humoral immune system.Antibodies are produced by a type of white blood cell called a plasma cell. Antibodies can occur in two physical forms, a soluble form that is secreted from the cell, and a membrane-bound form that is attached to the surface of a B cell and is referred to as the B cell receptor. The BCR is only found on the surface of B cells and facilitates the activation of these cells and their subsequent differentiation into either antibody factories called plasma cells, or memory B cells that will survive in the body and remember that same antigen so the B cells can respond faster upon future exposure. In most cases, interaction of the B cell with a T helper cell is necessary to produce full activation of the B cell and, therefore, antibody generation following antigen binding.Soluble antibodies are released into the blood and tissue fluids, as well as many secretions to continue to survey for invading microorganisms.

Antibiotics-It is a compound or substance that kills or slows down the growth of bacteria. The term is often used synonymously with the term Antibiotics. Ioday, however, with increased knowledge of the causative agents of various infectious diseases, they has come to denote a broader range of antimicrobial compounds, including anti-fungal and other compounds.

With advances in medicinal chemistry, most of today's antibacterials chemically are semisynthetic modifications of various natural compounds. These include, for example, the beta-lactam antibacterials, which include the penicillins, the cephalosporins, and the carbapenems. Compounds that are still isolated from living organisms are the aminoglycosides, whereas other antibacterials—for example, the sulfonamides, the quinolones, and the oxazolidinones—are produced solely by chemical synthesis. In accordance with this, many antibacterial compounds are classified on the basis of biosynthetic origin into natural, semisynthetic, and synthetic. Another classification system is based on biological activity; in this classification, antibacterials are divided into two broad groups according to their biological effect on microorganisms: bactericidal agents kill bacteria, and bacteriostatic agents slow down or stall bacterial growth.

antibodies r produced by our bosy 2 fight against harmful micro-organisma ....n antibiotics r those which r made by micro-organisms dat kills / slows down d harmful bacteria..

antibodies are those substances that are produced by our body when a pathogen enters our body. it fight with the envader and keeps us fit

on the other hand antibiotics are those medicines which are made from microbes and are used to kill the pathogen .

antibodies are produced by our body automatically while we have to intake the antibiotics.

antibodies are some type of cells while antibiotics are medicines.
