4 Pharmacology and Biochemistry
4.1 MeSH Pharmacological Classification

Anticoagulants

Agents that prevent BLOOD CLOTTING. (See all compounds classified as Anticoagulants.)


Buffers

A chemical system that functions to control the levels of specific ions in solution. When the level of hydrogen ion in solution is controlled the system is called a pH buffer. (See all compounds classified as Buffers.)


Food Preservatives

Substances capable of inhibiting, retarding or arresting the process of fermentation, acidification or other deterioration of foods. (See all compounds classified as Food Preservatives.)
