- Definition [edit]. Allosteric control refers to a type of enzyme regulation involving the binding of a non-substrate molecule, known as the allosteric effector, at locations on the enzyme other than the active site. The name allo means other and steric refers to a position in a certain amount of space.n allosteric site is a site at which a small regulatory molecule interacts with an enzyme to inhibit or activate that specific enzyme; which is different from the active site where catalytic activity occurs. The binding of the allosteric effector is in general noncovalent and reversible.

Amphotericin B One of the main uses of amphotericin B is treating a wide range of systemic fungal infections. Due to its extensive side effects, it is often reserved for severe infections in critically ill, or immunocompromised patients.

Amphoterism Amphoteric oxides include lead oxide and zinc oxide, among many others. One type of amphoteric species are amphiprotic molecules, which can either donate or accept a proton (H+). Examples include amino acids and proteins, which have amine and carboxylic acid groups, and self-ionizable compounds such as water.

Amphoteric: Definition, Properties & Examples Video: Amphoteric: Definition, Properties & Examples. There are substances that can only act as an acid and those that can only act as a base. However, there are also substances that can do both - these are called amphoteric substances. In this lesson, we will learn all about the amphoteric substances.

Difference Between Amphiprotic and Amphoteric As amphiprotic and amphoteric are quite similar, the difference between amphiprotic and amphoteric too is quite confusing. Both of the terms, amphiprotic and amphoteric, are both related to acid – base chemistry. Amphoteric substances behaves as an acid and as a base.

Pseudohalogen  [show article only]hover over links in text for more info Water is amphoteric, meaning it is both an acid and a base—it produces H+ and OH− ions by self ionization. This regulates the concentrations of H+ and OH− ions in water. Because water is a very good solvent, it is rarely pure and some of the properties of impure water can vary from those of the pure substance.

Ampicillin Ampicillin is an antibiotic used to prevent and treat a number of bacterial infections. This includes respiratory tract infections, urinary tract infections, meningitis, salmonella infections, and endocarditis. It may also be used to prevent group B streptococcal infection in newborns.mpicillin acts as an irreversible inhibitor of the enzyme transpeptidase, which is needed by bacteria to make their cell walls. It inhibits the third and final stage of bacterial cell wall synthesis in binary fission, which ultimately leads to cell lysis; therefore ampicillin is usually bacteriocidal.

Oxides An oxide that combines with water to give an acid is termed as an acidic oxide. The oxide that gives a base in water is known as a basic oxide. An amphoteric solution is a substance that can chemically react as either acid or base. However, it is also possible for an oxide to be neither acidic nor basic, but is a neutral oxide. There are different properties which help distinguish between the three types of oxides.

Xenomorph Facehugger Edit. A facehugger, is the second stage in the alien's life-cycle. Its bony finger-like legs allow it to crawl rapidly and its long tail can launch it in great leaps. These particular appendages give them an appearance comparable to Chelicerata arthropods such as arachnids and horseshoe crabs.

- Amphoteric surfactants are used in personal cleansing and household cleaning products for their mildness, sudsing and stability. They have the ability to be anionic (negatively charged), cationic (positively charged) or nonionic (no charge) in solution, depending on the pH (acidity or alkalinity) of the water. Imidazolines and betaines are the major amphoterics. Builders enhance or maintain the cleaning efficiency of the surfactant.
