A pheromone (from Ancient Greek φέρω (phérō) 'to bear' and hormone) is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to affect the behavior of the receiving individuals. [1]
All plasma proteins except Gamma-globulins are synthesised in the liver. [1] Human serum albumin, osmolyte and carrier protein; α-fetoprotein, the fetal counterpart of serum albumin; Soluble plasma fibronectin, forming a blood clot that stops bleeding; C-reactive protein, opsonin on microbes, [2] acute phase protein; Various other globulins
Plasma proteins, sometimes referred to as blood proteins, are proteins present in blood plasma. They serve many different functions, including transport of lipids, hormones, vitamins and minerals in activity and functioning of the immune system. Other blood proteins act as enzymes, complement components, protease inhibitors or kinin precursors.
Primer pheromones have a major influence on the organization of hymenopteran states formed by Hymenoptera and of termite colonies. These pheromones influence the hormonal system of the recipient; they often interfere with metabolism via a signaling cascade or activate proteins that can bind to DNA. In contrast to the releaser pheromones, the ...
Sweat is mostly water, but it does contain some electrolytes, since it is derived from blood plasma. The presence of sodium chloride gives sweat a salty taste. The total volume of sweat produced depends on the number of functional glands and the size of the surface opening.
A secretory protein is any protein, whether it be endocrine or exocrine, which is secreted by a cell. Secretory proteins include many hormones , enzymes , toxins , and antimicrobial peptides . Secretory proteins are synthesized in the endoplasmic reticulum.
In 2010, this definition of secretome was revised to include only proteins secreted into the extracellular space. [2] Related concepts include the matrisome , which is the subset of the secretome that includes extracellular matrix proteins and their associated proteins; [ 3 ] the receptome , which includes all membrane receptors, [ 4 ] and the ...
Pheromones, in general, are secreted chemical substances by organisms that trigger a social reaction in the same species. Sex pheromones are a special type of olfactory signal, produced to attract the opposite sex, to encourage mating or to perform some other function closely related to sexual reproduction .
