Common Name

N-delta-Acetylornithine

Description

N-delta-Acetylornithine is a member of the amino acid derivative chemical class, specifically an acetylated form of ornithine. Its chemical structure features an acetyl group attached to the nitrogen atom at the delta position of the ornithine backbone, which is a non-proteinogenic amino acid involved in the urea cycle and polyamine synthesis. N-delta-Acetylornithine is implicated in various metabolic pathways, including those associated with intervertebral disc degeneration (IVDD), as evidenced by its significant association with specific microbial genera and metabolites (PMID:40211528 ). Additionally, it has been positively correlated with certain microbial species while showing negative correlations with other metabolites, indicating its potential role in gut microbiota interactions (PMID:39897958 ). Elevated levels of N-delta-acetylornithine have also been linked to increased risks of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), suggesting its involvement in energy metabolism and stress responses (PMID:38660205 ). Furthermore, it has been identified in studies examining recurrent stroke outcomes and smoking status, highlighting its relevance in cardiovascular health (PMID:33661917 ; PMID:33361317 ).
