(S)-ATPA
A non-proteinogenic L-alpha-amino acid that is L-alanine in which one of the methyl hydrogens is replaced by a 5-tert-butyl-3-hydroxy-isooxazol-4-yl group.
Prolylhydroxyproline
Prolylhydroxyproline is a dipeptide. Prolylhydroxyproline is a marker of bone collagen degradation, showing high sensitivity for the diagnosis of osteoporosis. Prolylhydroxyproline has been suggested as a possible alternative to hydroxyproline determination in bone resorption studies. Prolylhydroxyproline is one of the iminodipeptides present in the urine of patients with prolidase deficiency. Prolidase (X-Pro dipeptidase EC 3.4. 13.9) splits iminodipeptides containing C-terminal proline or hydroxyproline (X-Pro or X-Hyp) to X+Pro or X+Hyp. Prolidase deficiency is a rare autosomal recessive disease characterized by chronic ulcerative dermatitis and mental retardation. These patients excrete large amounts of iminodipeptides containing C-terminal proline in the urine due to hereditary prolidase deficiency.

Pyroglutamylvaline
Pyroglutamylvaline, also known as pyro-Glu-Val or 5-oxoprolylvaline, is classified as a member of the dipeptides. Dipeptides are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Pyroglutamylvaline is considered to be practically insoluble (in water) and acidic.
Hydroxyprolyl-Proline
Hydroxyprolyl-Proline is a dipeptide composed of hydroxyproline and proline. 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.
Tetraacetylethylenediamine
Bleach activator used in food-contact paper and paperboard. TAED is an important component of detergents and bleaches. Its is an activator for "active oxygen" bleaching agents. Such active oxygen bleaching agents release hydrogen peroxide during the wash cycle. Such agents include sodium perborate, sodium percarbonate, sodium perphosphate, sodium persulfate, and urea peroxide. The released hydrogen peroxide is an inefficient bleach below 40 °C, except in the presence of activators such as TAED. Tetraacetylethylenediamine, commonly abbreviated TAED, is an organic compound with the formula (CH3C(O))2NCH2CH2N(C(O)CH3)2. This colourless compound is often dyed blue or green for use in laundry detergents, its most significant application. It is produced by acetylation of ethylenediamine. The activation process entails a reaction of the hydrogen peroxide with TAED to release peracetic acid, which is a fast-acting bleaching agent.:.
