Annual Review of Microbiology, 1958
The ultimate source of nitrogen for all forms of life is inorganic nitro gen. The nitrogen atom has a variety of oxidation states ranging from the disputed oxidation level of plus six as represented by the presumed short half-lived NOs [Wells ( 1 ) ] through the oxidation states of plus five (N205 or its hydrated form, HNOs); plus four (NO.); plus ...

Annual Review of Plant Physiology, 1955
The two years that have elapsed since the appearance of the last review on this subject (1) have witnessed a substantial increase in our knowledge the detailed biochemical pathways involved in nitrogen metabolism in plants. In addition, considerable information has accumulated on (a) the identification of hitherto unsuspected nitrogenous plant ...

Nitrogen Metabolism After Fracture
Nature, 1948AFTER a severe injury, such as a fracture, nitrogen balance usually becomes negative and the body loses nitrogen. The extent to which local effects of the injury (damage to tissues and disuse atrophy of muscles) contribute to this outpouring of nitrogen appears to have received little attention.

Nitrogen metabolism: nucleotide metabolism
2018This chapter talks about nucleotides. These are synthesized de novo. Purine nucleotides are synthesized by a salvage pathway via ribotidation of free bases released by the degradation of nucleotides. The chapter reviews the de novo synthesis of purine nucleotides, wherein the purine ring that is assembled by a series of steps in which the intermediates

Nitrogen metabolism: amino acid metabolism
2018This chapter refers to amino acids which are supplied in the diet from protein hydrolysis in the gut. This includes proteins in the body that are constantly degraded and resynthesized. The chapter clarifies how the body can synthesize about ten of the amino acids.
