title: Sialosphingolipids of sea urchin eggs and spermatozoa showing a characteristic composition for species and gamete.
abstract: 1. Sialosphingolipids of four species of the Japanese sea urchin were compared. The composition of sialosphingolipids was characteristic for species and gamete. 2. It is suggested that sialosphingolipids may have a common carbohydrate backbone composed solely of hexoses and sialic acids.
