title: SIALIC ACID-CONTAINING GLYCOPEPTIDE FROM CHLORELLA.
abstract: A C(14)-labeled polyanion was isolated from Chlorella pyrenoidosa. It contained amino acids, sialic acid, and other carbohydrates, but no uronic acids, phosphate, or sulfate. It was stable to mild alkali, but released sialic acid upon mild acid treatment.
