Chlorogenic acid is the ester of caffeic acid and (-)-quinic acid. Chlorogenic acid is a naturally occurring plant metabolite and can be found with the related compounds cryptochlorgenic acid and neochlorogenic acid in the leaves of Hibiscus sabdariffa, coffee, potato, eggplant, peaches, and prunes. Chlorogenic acid has been investigated as a dietary supplement to improve glucose intolerant hypoglycemia and non-alcoholic fatty liver disease. It has also been identified as a potential anticancer agent by reducing the expression of HIF-1a and Sphingosine Kinase-1. Chlorogenic acid was also identified as a neuraminidase blocker effective against influenza A virus (H1N1 and H3N2).

DL-Cystine is a racemic mixture of the proteinogenic amino acids L-cystine and the non-proteinogenic D-cystine. Cystine is the oxidized dimer form of the amino acid cysteine. L-Cystine serves two biological functions, a site of redox reactions and a mechanical linkage that allows proteins to retain their 3-dimensional structure. DL-cystine is used in the preparation of sulfur-containing dimeric and monomeric surfactants.
