They are also found frequently, but not always, as constituents of cell envelopes of archaebacteria (Sumper 1987). The possibility of rare occurrence in eubacteria (Messner and Sleytr 1988) is still under debate.

In these membranes, sterols play a major role both architecturally and functionally. The most common membrane sterol in animals is cholesterol

Aufbau der modernen Kostenrechnung,way. The conversion of this 30-carbon hydrocarbon to the tetracyclic lanosterol structure was originally thought to occur in one step without intermediates. Tchen and Bloch (1957) showed that rat liver extracts require oxygen and reduced pyridine nucleotide to perform cyclisation of squalene. Yeast
