L-L-Homoglutathione

2-amino-4-[(Z)-{1-[(Z)-(2-carboxyethyl)-C-hydroxycarbonimidoyl]-2-sulfanylethyl}-C-hydroxycarbonimidoyl]butanoic acid

C11H19N3O6S (321.0995)

L-l-homoglutathione is a member of the class of compounds known as hybrid peptides. Hybrid peptides are compounds containing at least two different types of amino acids (alpha, beta, gamma, delta) linked to each other through a peptide bond. L-l-homoglutathione is practically insoluble (in water) and a moderately acidic compound (based on its pKa). L-l-homoglutathione can be found in pulses, which makes L-l-homoglutathione a potential biomarker for the consumption of this food product. L-L-Homoglutathione is found in pulses. L-L-Homoglutathione occurs in seeds of various legume

2-Amino-4-oxo-4-alpha-hydroxy-6-(erythro-1',2',3'-trihydroxypropyl)-5,6,7,8-tetrahydroxypterin

2-Amino-4-oxo-3,4,5,6,7,8-hexahydro-6-(erythro-1,2,3-trihydroxypropyl)-5,6,7,8-tetrahydroxypteridine

C9H15N5O8 (321.0921)

2-Amino-4-oxo-4-alpha-hydroxy-6-(erythro-1,2,3-trihydroxypropyl)-5,6,7,8-tetrahydroxypterin is a pterin derivative. Pterin is a heterocyclic compound composed of a pyrazine ring and a pyrimidine ring with Several tautomers; the pyrimidine ring has a carbonyl oxygen and an amino group. As a group, pterins are compounds that are derivatives of 2-amino-4-oxopteridine, with additional functional groups attached to the pyrazine ring. Pterins were first discovered in the pigments of butterfly wings and perform many roles in coloration in the biological world. Pterins also function as cofactors in enzyme catalysis (Wikipedia). Some pterin derivatives (biopterin, 6-formylpterin, 6-carboxypterin) accumulate in the skin of patients affected by vitiligo, a depigmentation disorder, where the protection against UV radiation fails due to the lack of melanin. Pterins participate in biologically important photosensitization processes; for example, pterins act as sensitizers in photochemical reactions that induce DNA damage4,5 and are able to generate singlet molecular oxygen6 and other reactive oxygen species (PMID: 19199487). 2-Amino-4-oxo-4-alpha-hydroxy-6-(erythro-1,2,3-trihydroxypropyl)-5,6,7,8-tetrahydroxypterin is a pterin derivative.
