Unreferenced date December 2009 Nitrogen assimilation is a fundamental biological process that occurs in plant s and algae that are incapable of independent nitrogen fixation . The assimilation of nitrogen has marked effects on plant productivity, biomass, and crop yield, and nitrogen deficiency leads to a decrease in structural components. Initial conversion of nitrate to nitrite by nitrate reductase is followed by a reduction to ammonia by nitrite reductase also called nitrite oxidoreductase . The ammonia is incorporated into glutamine as an amido nitrogen and is reductively transferred to 2 oxoglutarate to form 2 molecule s of glutamate by glutamate synthase. The general steps of assimilation have been known for several years, however, the chemical mechanisms that occur in these processes remain poorly understood in large part due to the lack of detailed structural information concerning the enzyme s that catalyze these reactions.

A positive value is often found during periods of growth, tissue repair or pregnancy. This means that the intake of nitrogen into the body is greater than the loss of nitrogen from the body, so there is an increase in the total body pool of protein. A negative value can be associated with burns, fevers, wasting diseases and other serious injuries and during periods of fasting.
