Graphene (/ËÉ¡rÃ¦f.iËn/) is an allotrope of carbon in the form of a two-dimensional, atomic-scale, hexagonal lattice in which one atom forms each vertex. It is the basic structural element of other allotropes, including graphite, charcoal, carbon nanotubes and fullerenes.
Proton pump inhibitors are a type of acid reducer that helps to decrease levels of acid in your stomach. They work by causing your body to make less stomach acid. This helps to treat heartburn and acid reflux problems. Another type of acid reducer, in addition to a proton pump inhibitor, is an H2 blocker.
Purpose. Proton pump inhibitors are used to treat ulcers; gastroesophageal reflux disease (GERD), a condition in which backward flow of acid from the stomach causes heartburn and injury of the food pipe (esophagus); and conditions in which the stomach produces too much acid, such as Zollinger-Ellison syndrome.efinition. The proton pump inhibitors are a group of drugs that reduce the secretion of gastric (stomach) acid. They act by binding with the enzyme H+, K(+)-ATPase, hydrogen/potassium adenosine triphosphatase, which is sometimes referred to as the proton pump.
