A freshwater aquatic food web. The blue arrows show a complete food chain (algae → Daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
Oleylamine reacts with carboxylic acid to form its carboxylate salt through an exothermic reaction. [8] [9] Its carboxylate salt can further condensate into amides through the loss of one water molecule. In the presence of acetic acid, oleylamin forms with DNA insoluble complexes with the radii of the particles equal 60–65 nm. [10]
Oleoylethanolamide (OEA) is an endogenous peroxisome proliferator-activated receptor alpha (PPAR-α) agonist.It is a naturally occurring ethanolamide lipid that regulates feeding and body weight in vertebrates ranging from mice to pythons.

A community matrix model is a type of interaction web that uses differential equations to describe every link in the topological web. Using Lotka–Volterra equations, that describe predator-prey interactions, and food web energetics data such as biomass and feeding rate, the strength of interactions between groups is calculated.

Synthetic oleamide has a variety of industrial uses, including as a lubricant. [15] Oleamide was found to be leaching out of polypropylene plastics in laboratory experiments, affecting experimental results. [16] Since polypropylene is used in a wide number of food containers such as those for yogurt, the problem is being studied. [17]

Food chain in a Swedish lake. Osprey feed on northern pike, which in turn feed on perch which eat bleak which eat crustaceans.. A food chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae), also called a producer, and typically ending at an apex predator (such as grizzly bears or killer whales), detritivore (such as earthworms and woodlice ...
