Nitrite-positive urine is a sign of a possible urinary tract infection (UTI) caused by bacteria. Learn how a urinalysis detects nitrites in urine, how antibiotics treat UTIs and how to prevent them.
Nitrite is a compound of nitrogen and oxygen, formed by natural and human activities. Learn about its uses, health impacts, and how to prevent and treat nitrite contamination in water, food, and soil.
Nitrates and nitrites are natural chemicals in some foods, but added to others as preservatives. Learn how they affect your health, from heart benefits to cancer risks, and which foods to choose.
nitrite, any member of either of two classes of compounds derived from nitrous acid.Salts of nitrous acid are ionic compounds containing the nitrite ion, NO-2, and a positive ion such as Na + in sodium nitrite (NaNO 2).Esters of nitrous acid are covalent compounds having the structure R―O―N―O, in which R represents a carbon-containing combining group such as ethyl (C 2 H 5) in ethyl nitrite.
Nitrate (NO 3) and nitrite (NO 2) widely exist in water, soil, air, and plants [].The main source of absorbed nitrate in the body is food, with green vegetables contributing the major portion. Although nitrates are stable, dietary nitrate is converted to nitrite through a non-enzymatic process and nitric oxide (NO) by symbiotic bacteria in the oral cavity and stomach, therefore performing ...
