In pharmacology, biological activity or pharmacological activity describes the beneficial or adverse effects of a drug on living matter. [1] [2] When a drug is a complex chemical mixture, this activity is exerted by the substance's active ingredient or pharmacophore but can be modified by the other constituents. Among the various properties of ...
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Biological processes are regulated by many means; examples include the control of gene expression, protein modification or interaction with a protein or substrate molecule. Homeostasis : regulation of the internal environment to maintain a constant state; for example, sweating to reduce temperature
Biological interactions range from mutualism, beneficial to both partners, to competition, harmful to both partners. Interactions can be direct when physical contact is established or indirect, through intermediaries such as shared resources, territories, ecological services, metabolic waste, toxins or growth inhibitors.
Metabolism (/ m ə ˈ t æ b ə l ɪ z ə m /, from Greek: μεταβολή metabolē, "change") is the set of life-sustaining chemical reactions in organisms.The three main functions of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks of proteins, lipids, nucleic acids, and some carbohydrates; and the ...
Biological activity, the effect of a drug or compound on living matter; Bioactive compounds, a compound that has an effect on a living organism, tissue /cell; Bioactive glass,a group of surface reactive glass-ceramic biomaterials used as implanted devices in the human body to repair and replace diseased or damaged bones
Additionally, the number of structural analogues available for structure–activity analysis (SAR) is limited by the biology of the organism, and thus beyond experimental control. [ 125 ] When the desired product is difficult to obtain or modify to create analogs, a middle-to-late stage biosynthetic precursor or analog can sometimes be used to ...
In physiology, a function is an activity or process carried out by a system in an organism, such as sensation or locomotion in an animal. [1] This concept of function as opposed to form (respectively Aristotle's ergon and morphê [2]) was central in biological explanations in classical antiquity.
