Chemical biology Chemical biology is a scientific discipline spanning the fields of chemistry, biology, and physics.hemical biologists attempt to use chemical principles to modulate systems to either investigate the underlying biology or create new function. Research done by chemical biologists is often closer related to that of cell biology than biochemistry.

Chain reaction A chemical chain reaction proceeds by a sequence generally subdivided into three stages: (1) Initiation, in which a reactive intermediate, which may be an atom, an ion, or a neutral molecular fragment, is formed, usually through the action of an agent such as light, heat, or a catalyst.

Chemical reaction A chemical reaction is a process that always results in the interconversion of chemical substances. The substance or substances initially involved in a chemical reaction are called reactants.Chemical reactions are usually characterized by a chemical change, and they yield one or more products, which usually have properties different from the reactants. chemical reaction is a process that always results in the interconversion of chemical substances.

Types of Chemical Reactions A chemical reaction is a process that is usually characterized by a chemical change in which the starting materials (reactants) are different from the products. Chemical reactions tend to involve the motion of electrons, leading to the formation and breaking of chemical bonds. Direct Combination or Synthesis Reaction. 2  In a synthesis reaction two or more chemical species combine to form a more complex product. 3  A + B → AB. 4  The combination of iron and sulfur to form iron (II) sulfide is an example of a synthesis reaction :

Feedback mechanism Feedback mechanism. Definition. noun. (1) A loop system in which the system responds to perturbation either in the same direction (positive feedback) or in the opposite direction (negative feedback).(2) A process in which the level of one substance influences the level of another substance.(3) A mechanism or a signal that tends to initiate (or accelerate) or to inhibit (or slow down) a process. Supplement. An example of positive feedback loop is the onset of contractions in childbirth.2) A process in which the level of one substance influences the level of another substance.

Chemistry A chemical reaction can be envisioned to take place in a number of steps, each of which may have a different speed. Many reaction intermediates with variable stability can thus be envisaged during the course of a reaction. Reaction mechanisms are proposed to explain the kinetics and the relative product mix of a reaction. Many physical chemists specialize in exploring and proposing the mechanisms of various

Chemical equation (September 2011). A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side.he stoichiometric coefficients (the numbers in front of the chemical formulas) result from the law of conservation of mass and the law of conservation of charge (see Balancing Chemical Equation section below for more information).

Reaction mechanism In chemistry, a reaction mechanism is the step by step sequence of elementary reactions by which overall chemical change occurs. A chemical mechanism describes in detail exactly what takes place at each stage of an overall chemical reaction (transformation).It also describes each reactive intermediate, activated complex, and transition state, and which bonds are broken (and in what order), and which bonds are formed (and in what order). reaction mechanism must also account for the order in which molecules react. Often what appears to be a single-step conversion is in fact a multistep reaction.

Chemical reaction In biochemistry, a consecutive series of chemical reactions (where the product of one reaction is the reactant of the next reaction) form metabolic pathways. These reactions are often catalyzed by protein enzymes.he general concept of a chemical reaction has been extended to reactions between entities smaller than atoms, including nuclear reactions, radioactive decays, and reactions between elementary particles as described by quantum field theory.

Absorption, Distribution, and Storage of Chemicals The cell membrane consists mainly of phospholipids and proteins in the form of a lipid bilayer. Mechanisms for moving chemicals through the cell membrane include: passive diffusion, facilitated diffusion, active transport, and endocytosis. Factors such as human anatomy and chemical structures affect the movement of chemicals in the body.

- A chemical reaction is the process in which atoms present in the starting substances rearrange to give new chemical combinations present in the substances formed by the reaction. These starting substances of a chemical reaction are called the reactants, and the new substances that result are called the products. properly written chemical equation provides information about reactants, products, molecule-to-molecule relationships between reactants and products, and mole-to-mole relationships. between reactants and products.
