Feedback inhibition occurs when the end product of a reaction interferes with the enzyme that helped produce it. The inhibitor does this by binding to a second active binding site that's different from the one attached to the initial reactant. The enzyme then changes its shape and can't catalyze the reaction anymore. This type of inhibition is done as a regulatory mechanism to meet the metabolic needs of the cell or organism.
Formaldehyde is a chemical compound that is widely used in industrial manufacturing and a number of other industries. Many people are familiar with it in the form of formalin, an aqueous solution of formaldehyde that is used as an embalming preservative. This chemical is toxic, known to cause cancer and a variety of other health problems, and for this reason, most people make an effort to avoid it.
Formaldehyde is a colorless, flammable, strong-smelling chemical that is used in building materials and to produce many household products. It is used in pressed-wood products, such as particleboard, plywood, and fiberboard; glues and adhesives; permanent-press fabrics; paper product coatings; and certain insulation materials.
