Ara H 3
Ara h 3 is a seed storage protein from ''Arachis hypogaea'' (peanuts). It is a heat stable 11S legumin-like globulin with a stable trimeric form that comprises 19% of the total protein in peanut extracts. Structure Ara h 3 forms homotrimers and has a highly stable structure, mediated through hydrophobic interactions. It has been established as an allergen. The trimeric assemblies are stabilized by multiple hydrogen bonds. Influence of Ara h 3 in peanut allergies The protein Ara h 3 plays an important role in peanut allergic reactions. Ara h 3 makes up 19% of the total protein in peanut extracts and is classified as a major peanut allergen because it provokes sensitization of patients with this allergy. This protein is a very potent allergen and it causes a severe reaction. The symptoms can be: * Skin reaction: urticarial, redness or edema. * Itchy reaction: usually around the mouth and throat. * Digestive problems: such as diarrhea, stomach cramps, nausea or vomiting. * Br ...

Arachis Hypogaea
The peanut (''Arachis hypogaea''), also known as the groundnut, goober (US), pindar (US) or monkey nut (UK), is a legume A legume () is a plant in the family Fabaceae (or Leguminosae), or the fruit or seed of such a plant. When used as a dry grain, the seed is also called a pulse. Legumes are grown agriculturally, primarily for human consumption, for livestock f ... crop grown mainly for its edible Seed, seeds. It is widely grown in the tropics and subtropics, important to both small and large commercial producers. It is classified as both a grain legume and, due to its high oil content, an oil crop. World annual production of shelled peanuts was 44 million tonnes in 2016, led by China with 38% of the world total. Atypically among legume crop plants, peanut pods develop underground (geocarpy) rather than above ground. With this characteristic in mind, the botanist Carl Linnaeus gave peanuts the specific epithet ''hypogaea'', which means "under the earth." The peanut bel ...
