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.
Casein is a protein that is found in milk and used independently in many foods as a binding agent. Technically, it is part of a group called phosphoproteins, collections of proteins bound to something containing phosphoric acid.It may also be called caseinogen, particularly in European foods.) Casein is a slow acting protein (opposite of whey) that is ideal for taking right before sleep if you are in the bodybuilding game. 6) Saying something causes cancer blindly and something does not is total ignorance because each individual reacts differently.
