5,6-Dihydrouridine
Dihydrouridine is a pyrimidine which is the result of adding two hydrogen atoms to a uridine. Dihydrouridine is found only in tRNA molecules. An inhibitor of nucleotide metabolism. [HMDB] Dihydrouridine (abbreviated as D,[1] DHU, or UH2) is a pyrimidine nucleoside which is the result of adding two hydrogen atoms to a uridine, making it a fully saturated pyrimidine ring with no remaining double bonds. D is found in tRNA and rRNA molecules as a nucleoside; the corresponding nucleobase is 5,6-dihydrouracil. Because it is non-planar, D disturbs the stacking interactions in helices and destabilizes the RNA structure. D also stabilizes the C2’-endo sugar conformation, which is more flexible than the C3’-endo conformation; this effect is propagated to the 5’-neighboring residue. Thus, while pseudouridine and 2’-O-methylations stabilize the local RNA structure, D does the opposite.[2] The tRNAs of organisms that grow at low temperatures (psychrophiles) have high 5,6-dihydrouridine levels (40-70\\\% more on average) which provides the necessary local flexibility of the tRNA at or below the freezing point.[3] Dihydrouridine.

Aspartylhydroxyproline
Aspartylhydroxyproline is a dipeptide found in urine (PMID: 3782411). It is likely a proteolytic breakdown product of collagen. Aspartylhydroxyproline belongs to the family of peptides. These are compounds containing an amide derived from two or more amino carboxylic acid molecules (the same or different) by the formation of a covalent bond from the carbonyl carbon of one to the nitrogen atom of another. L-alpha-Aspartyl-L-hydroxyproline is a dipeptide found in urine (PMID: 3782411). It is likely a proteolytic breakdown product of collagen. [HMDB]
