![The nitrate/nitrite/nitric oxide (NO 3 − /NO 2 − /NO) pathway after beetroot juice (BRJ) ingestion. Next to BRJ ingestion, oral microbiota on the posterior surface of the tongue is able to reduce NO 3 − to NO 2 − by means of their enzymatic machinery. The strict anaerobes Veillonella atypical and Veillonella dispar are the most important NO 3 − reducers; however, Actinomyces, Rothia, Prevotella, Neisseria, and Haermophilus are also present on the oral cavity. Even though this non-enzymatic reduction process continues in stomach, where more NO 2 − and NO are produced due to the acid environment, a considerable amount of NO 3 − from blood (≈25%) is taken up by an electrogenic 2NO 3 − /H + symporter called SLC17A5 (also known as sialin, UniProt ID: Q9NRA2) in the salivary gland acinar cells [14]. Both dietary and saliva NO 3 − , and its reduced forms NO 2 − and NO,](https://i0.wp.com/www.researchgate.net/profile/Diego-Bonilla-2/publication/328730123/figure/fig1/AS:689115192385537@1541309273724/The-nitrate-nitrite-nitric-oxide-NO-3-NO-2-NO-pathway-after-beetroot-juice-BRJ.jpg?ssl=1)
