Nitrates

Nitrates

A group of medications that are made from a chemical with a nitrogen base. Nitrates relax smooth muscle, dilate veins, lower blood pressure and improve blood flow through the coronary arteries.

Examples include: nitroglycerin, erythrityl tetranitrate, isosorbide dinitrate, isosorbide mononitrate and pentaerythritol tetranitrate.


nitrates are minerals needed by plants, to produce protein in order for the plant to grow. Nitrates may be obtained by the plant via the root Hair cells on roots by active uptake/transport.

A2 nitrogen fixation + denitrification

Sorry but I have no idea. I guess they have to uptake nitrogen as nitrates because thats the only form that they can absorb? How would they convert ammonia into amino acids? I thought that ammonification converted amino acids to ammonia so that it could be ...

A2 nitrogen fixation + denitrification

I'm taking it back. Why should plants uptake nitrogen as nitrates? Why not incorporate ammonia into amino acids? Regarding your last post, there are bacteria converting NO3- to NO2- and bacteria converting NO2- to N2 ;)

A2 nitrogen fixation + denitrification

I think its that denitrifing bacteria in the soil convert the excess nitrates into nitrites and then nitrogen gas so that the nitrogen can be put back into the cycle. Otherwise in waterlogged soil, there would be a load of nitrogen in the form of nitrates ...

A2 nitrogen fixation + denitrification

... nitrogen gas from the soil and converts it into ammonium compounds. This (after nitrification) allows plants to take up nitrogen in the form of nitrates. denitrification occurs in anaerobic conditions and converts the nitrates which aren't taken up by plants (due to lack of oxygen so plants ...
