Water soluble carbohydrates were studied at various developmental stages in the cellular slime mold, Dictyostelium discoideum. The only water soluble sugars found were, the non-reducing disaccharide, trehalose and glucose. The level of trehalose varied very dramatically during the life cycle. Throug

✦ Synopsis
In the slime mold Dictyostelium discoideum polysioprenylphosphomannosides are substrates for membrane bound mannosyltransferases; the isolated and purified isoprenyl derivatives transfer mannose to protein in vitro in presence of membrane fractions. The biosynthesis of the mannolipids as well as the biosynthesis of a glucose containing cerebroside, which becomes synthesized in an early stage of the cell development proceeds under control of the cell differentiation. The isolation procedure and the properties of the glycolipids are described, and their functions for the cellular development are discussed.

## T W O FIGURES I n the Acrasiales or amoeboid slime molds, there is, in their development, first a period of active feeding, growth and cell division (the vegetative stage) followed by the aggregation of the cells and subsequent morphogenesis of the collected cell mass or pseudoplasmodium. It is
