Dehydration synthesis is the formation of a new compound by the removal of oxygen and hydrogen from reactants, while hydrolysis is the breakdown of a compound through a chemical reaction with water. These opposite processes are very common in nature and in life. One common non-biological form of hydrolysis is the dissolution of salt in water, a process which breaks apart the ionic bonds between the sodium and chloride ions.Continue Reading
Hydrogen and oxygen are a part of a vast number of biological and non-biological compounds, and water can easily react with other compounds in the right circumstances to form them. One way this happens is in acid-based reactions. The pH of water falls exactly in the middle of the acid-base scale, and it can act as either an acid, proton donator, or base, a proton acceptor. In the presence of acetic acid, also known as vitamin C, it accepts a proton, or hydrogen nucleus, to become the positive hydronium ion. This is an example of acid hydrolysis. If another base is present, it will often donate the proton to the base in turn.
The opposite happens with the weak base, ammonia. In water, ammonia accepts a hydrogen ion to become ammonium, leaving a hydroxide ion as the other chemical product.Learn more about Cells
According to the Fayette County Public Schools, the breakdown of adenosine triphosphate (ATP) in a chemical reaction with water provides energy for skeletal muscles to contract. Since the amount of ATP stored in muscles is small, metabolic pathways that generate new ATP must be activated for continued muscle contraction. These pathways are either anaerobic (in the absence of oxygen) or aerobic (in the presence of oxygen).Full Answer >
A decomposition reaction occurs between catalase and hydrogen peroxide, where catalase speeds up the breakdown of hydrogen peroxide into oxygen and water. The general equation for the reaction is 2H2O2 -> 2H2O + O2.Full Answer >
Acid-catalyzed dehydration is an important elimination reaction in organic chemistry, whereby water is removed from a compound, according to Old Dominion University. This chemical process is very important in converting alcohols into alkenes. During the process of acid-catalyzed dehydration, alcohols experience either E1 or E2 mechanisms that result in them losing water and thus forming a double molecular bond.Full Answer >
Glucose and oxygen are the reactants of cellular respiration. In the presence of oxygen, the chemical bonds in glucose break down, creating a form of energy known as ATP that is used by cells to perform their daily functions. Water and carbon dioxide are also formed when glucose and oxygen react, but these products are expelled from the body as waste.Full Answer >
