Geranylfarnesyl diphosphate
Geranylfarnesyl diphosphate reacts with isopentenyl diphosphate to produce all-trans-hexaprenyl diphosphate and diphosphate. The reaction is catalyzed by a all-trans-hexaprenyl-diphosphate synthase enzyme.

Dolichyl diphosphate
(C5H8)nC20H38O7P2 (681010.1147)
The glycosylation of asparagine residues in proteins is known to occur by transfer from a dolichyl diphosphate oligosaccharide containing glucose. The addition of all three glucoses to the dolichyl diphosphate oligosaccharide occur with dolichyl phosphate glucose as donor.(http://www.blackwell-synergy.com/links/doi/10.1111/j.1432-1033.1980.tb04498.x/abs/) [HMDB]. Dolichyl diphosphate is found in many foods, some of which are taro, winter squash, sweet rowanberry, and oregon yampah. The term dolichol refers to a group of long-chain mostly unsaturated organic compounds consisting of a variable number of isoprene units that terminate with an alpha-saturated isoprenoid group containing an alcohol functional group. In the form of dolichol phosphate, dolichols help facilitate protein N-glycosylation (Wikipedia). Glycosylation of asparagine residues in proteins is carried out by transferring glucose from a dolichyl diphosphate oligosaccharide (PMID: 7379786).
