The potential of bio based plastics for replacement of petrochemical plastics is 90%, corresponding to 240 million tons per year.1 Bio-based materials such as polynucleotides, polyamides, polysaccharides, polyoxoesters, polythioesters, polyanhydrides, polyisoprenoids and polyphenols are potential candidates for substitution of synthetic plastics.2 Polyhydroxyalkanoates (PHAs), belonging the gro...

The effect of sterol carrier protein-2 (SCP-2) on dolichol biosynthesis by rat liver microsomes was investigated. cis-Prenyltransferase activity was stimulated 7-fold in the presence of 5 micrograms of purified SCP-2/mg of microsomal protein, which was similar to the increase obtained by adding detergent. The polyisoprenoid pattern obtained in the presence of SCP-2 was the same as that present ...

Polyisoprenoid alcohols, linear polymers of isoprenoid residues are widespread in nature from bacteria to human cells. Their structures, distribution and biogenesis will be highlighted. Membrane localization of polyisoprenoid alcohols within the cell and techniques used for structural elucidation will be presented. Attention will be focused on the biosynthesis of polyisoprenoid alcohols in plan...
