Common NameN-Acetylornithine
DescriptionN2-Acetylornithine belongs to the class of organic compounds known as n-acyl-l-alpha-amino acids. These are n-acylated alpha amino acids which have the L-configuration of the alpha-carbon atom. N2-Acetylornithine exists in all living species, ranging from bacteria to plants to humans. N2-Acetylornithine is found, on average, in the highest concentration within a few different foods, such as wheats (Triticum), nanking cherries (Prunus tomentosa), and red raspberries (Rubus idaeus) and in a lower concentration in red bell peppers (Capsicum annuum), dills (Anethum graveolens), and carrots (Daucus carota ssp. sativus). N2-Acetylornithine has also been detected, but not quantified in, several different foods, such as arabica coffees (Coffea arabica), pears (Pyrus communis), black chokeberries (Photinia melanocarpa), macadamia nuts (Macadamia), and garland chrysanthemums (Chrysanthemum coronarium). This could make N2-acetylornithine a potential biomarker for the consumption of these foods. N2-Acetylornithine is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a significant number of articles have been published on N2-Acetylornithine.
