Oftentimes, scavenger communities differ in consistency due to carcass size and carcass types, as well as by seasonal effects as consequence of differing invertebrate and microbial activity. [4] Competition for carrion results in the inclusion or exclusion of certain scavengers from access to carrion, shaping the scavenger community.
A scavenger in chemistry is a chemical substance added to a mixture in order to remove or de-activate impurities and unwanted reaction products, for example oxygen ...
Scavenger is an organism that seeks and feeds on discarded or abandoned material such as carrion or detritus. ... science fiction film; The Scavengers, ...
It appears that the major scavenger cell systems of vertebrates and invertebrates are based on a dual-cell principle of waste clearance. [11] In vertebrates, distinct populations of scavenger endothelial cells represent the professional pinocyte, clearing the blood of a wide range of soluble macromolecules and small particles (<200 nm) by clathrin-mediated endocytosis, [13] while the ...
The components of an oxygen absorber vary according to intended use, the water activity of the product being preserved, and other factors. Often the oxygen absorber or scavenger is enclosed in a porous sachet or packet but it can also be part of packaging films and structures. [4] Others are part of a polymer structure. [5]
Scavenger resins are polymers (resins) with bound functional groups that react with specific by-products, impurities, or excess reagents produced in a reaction. Polymer-bound functional groups permit the use of many different scavengers, as the functional groups are confined within a resin or are simply bound to the solid support of a bead.

The scavenger receptor superfamily is defined by its ability to recognize and bind a broad range of common ligands. These ligands include: polyanionic ligands including lipoproteins, apoptotic cells, cholesterol ester, phospholipids, proteoglycans, ferritin, and carbohydrates. [ 4 ]
