Prolyl-Threonine

3-Hydroxy-2-{[hydroxy(pyrrolidin-2-yl)methylidene]amino}butanoate

C9H16N2O4 (216.111)

Prolyl-Threonine is a dipeptide composed of proline and threonine. It is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis. This dipeptide has not yet been identified in human tissues or biofluids and so it is classified as an Expected metabolite.

Threonylproline

(2S)-1-[(2S,3R)-2-amino-3-hydroxybutanoyl]pyrrolidine-2-carboxylic acid

C9H16N2O4 (216.111)

Threonylproline is a dipeptide composed of threonine and proline. It is an incomplete breakdown product of protein digestion or protein catabolism. Dipeptides are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Some dipeptides are known to have physiological or cell-signalling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis.

N2,N5-Diacetylornithine

(2S)-2,5-diacetamidopentanoic acid

C9H16N2O4 (216.111)

N2,N5-Diacetylornithine, also known as bisorcic, 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,N5-Diacetylornithine is an N-acetyl-L-amino acid that is L-ornithine carrying two acetyl substituents at positions N-2 and N-5. N2,N5-Diacetylornithine was identified as one of forty plasma metabolites that could be used to predict gut microbiome Shannon diversity (PMID: 31477923). Shannon diversity is a metric that summarizes both species abundance and evenness, and it has been suggested as a marker for microbiome health.

2,5-Bis(acetylamino)pentanoic acid

2,5-Bis[(1-hydroxyethylidene)amino]pentanoate

C9H16N2O4 (216.111)

[(2S,3R)-2-Amino-3-hydroxybutanoyl] (2S)-pyrrolidine-2-carboxylate

[(2S,3R)-2-Amino-3-hydroxybutanoyl] (2S)-pyrrolidine-2-carboxylic acid

Isoketocamphoric acid

3-(2-methyl-3-oxobutan-2-yl)pentanedioic acid

C10H16O5 (216.0998)

Isoketocamphoric acid, also known as isoketocamphate, is a member of the class of compounds known as medium-chain fatty acids. Medium-chain fatty acids are fatty acids with an aliphatic tail that contains between 4 and 12 carbon atoms. Isoketocamphoric acid is slightly soluble (in water) and a weakly acidic compound (based on its pKa). Isoketocamphoric acid can be found in common sage, which makes isoketocamphoric acid a potential biomarker for the consumption of this food product.
