Raphanuside, chemically known as (2S,4aS,6R,7S,8S,8aR)-2-(4-hydroxy-3,5-dimethoxyphenyl)-6-(hydroxymethyl)-3,4a,6,7,8,8a-hexahydro-2H-pyrano[3,2-b][1,4]oxathiine-7,8-diol, is a naturally occurring glycoside isolated from radish (Raphanus sativus) seeds. It features a complex polycyclic structure combining a pyran ring fused with an oxathiine ring, substituted with a hydroxymethyl group and two hydroxyl groups at positions 7 and 8, as well as a 4-hydroxy-3,5-dimethoxyphenyl moiety at position 2.

Porphyrin is a group of organic heterocyclic compounds that are comprised of four modified pyrrole subunits connected via methine bridges and form an aromatic macrocyclic structure, which has one or more side chains attached. Many porphyrins are naturally occurring pigments. Porphyrins with metal ions bound to the porphin ring can be cofactors for biological processes, such as oxygen transport by hemes and photosynthesis by chlorophyll.
