Bromide is present in typical seawater (35 PSU) with a concentration of around 65 mg/L, which is about 0.2% of all dissolved salts. Seafood and deep sea plants generally have higher levels than land-derived foods. Bromargyrite—natural, crystalline silver bromide—is the most common bromide mineral known but is still very rare. In addition to ...
This category is limited to chemical compounds which contain inorganic bromine in a -1 oxidation state. These may be metal salts containing bromide ion such as potassium bromide , or more covalent bromides of metals or nonmetals such as tantalum(V) bromide or phosphorus tribromide .
The largest living land animal, the African bush elephant, is a herbivore. This is a list of herbivorous animals, organized in a roughly taxonomic manner. In general, entries consist of animal species known with good certainty to be overwhelmingly herbivorous, as well as genera and families which contain a preponderance of such species.
Dogs and other animals that metabolize theobromine (found in chocolate) more slowly [35] can succumb to theobromine poisoning from as little as 50 g (1.8 oz) of milk chocolate for a smaller dog and 400 g (14 oz), or around nine 44-gram (1.55 oz) small milk chocolate bars, for an average-sized dog. The concentration of theobromine in dark ...
In biochemistry, naturally occurring phenols are natural products containing at least one phenol functional group. [1] [2] [3] Phenolic compounds are produced by plants and microorganisms. [4] Organisms sometimes synthesize phenolic compounds in response to ecological pressures such as pathogen and insect attack, UV radiation and wounding. [5]
Selenium, which is an essential element for animals and prokaryotes and is a beneficial element for many plants, is the least-common of all the elements essential to life. [ 3 ] [ 63 ] Selenium acts as the catalytic center of several antioxidant enzymes, such as glutathione peroxidase , [ 11 ] and plays a wide variety of other biological roles .
Plants in the Bromeliaceae are widely represented in their natural climates across the Americas. One species (Pitcairnia feliciana) can be found in Africa. [30] They can be found at altitudes from sea level to 4,200 meters, from rainforests to deserts. 1,814 species are epiphytes, some are lithophytes, and some are terrestrial
Organobromine chemistry is the study of the synthesis and properties of organobromine compounds, also called organobromides, [1] which are organic compounds that contain carbon bonded to bromine. The most pervasive is the naturally produced bromomethane .
