A SULFOLIPID IN PLANTS

Abstract
A sulfolipid occurs in high concentrations in photosynthetic tissues. It is readily labeled with S35 or C14 during photosynthesis by Chlorella. Radiochromatographic examination of the sulfolipid molecule revealed an anionic aldohexo-pyranosyl monoglyceride structure. Acid hydrolysis gave an acid-stable anionic hexose containing the sulfur. Periodate oxidation of the ethyl glycoside-sulfonate-cl''* produced 1 mole of formic acid. The structure of the sulfolipid consistent with the observed properties of l-0-([beta]-6''-deoxy-aldohexopyranosyl 6''-sulfonic acid)-3-0-oleoyl glycerol. The sulfonic acid structure suggests its origin by peroxidation of an-S-S-linked glycolipid in the photosynthetic apparatus.
