Example sentences for: unsaturated
How can you use “unsaturated” in a sentence? Here are some example sentences to help you improve your vocabulary:
Other unsaturated fatty acids also failed to stimulate Ppt1p activity with this substrate (Table 1).
Peroxisomes shorten chains of very long fatty acids, unsaturated fatty acids and branched fatty acids by β-oxidation [ 60 61 ] . They play critical roles in synthesis of ether phospholipids and cholesterol [ 62 63 ] . Peroxisomal abundance is associated with high membrane demand such as myelination in the central nervous system [ 64 65 ] and peroxisome diseases result in defective myelination [ 66 ] . Because the outer mitochondrial membrane normally tightly wraps around mitochondria, the extension of the outer membrane during vacuolation requires new membranes.
In the case of pNPP hydrolysis, others have reported both saturated and unsaturated fatty acyl coenzyme A esters stimulate PP5 activity, with concentrations required for half-maximal stimulation approximately 10-fold lower than those of their corresponding free fatty acids [ 21 ] . We therefore tested whether a saturated fatty acyl coenzyme A ester could also stimulate Ppt1p.
Like PP5, the dephosphorylation of 32P-MBP by Ppt1p was stimulated by arachidonic acid and other unsaturated fatty acids, but lipids lacking either a double bond or a carboxylate group were not effective (Table 1).
It has been proposed that vitamin E may incorporate into cellular membranes by association of the tocopherol side chain with the polyenoic fatty acid residues in the membrane fatty acids [ 15 19 ] . This interaction may stabilize cell membranes by making highly unsaturated fatty acids less liable to peroxidation as well as by making highly unsaturated fatty acids less available for phospholipid hydrolysis by phospholipase [ 15 16 ] . The latter action may reduce mobilization of arachidonic acid (AA) from the membranes and in this way reduce the amount of AA available as a substrate to cyclooxygenase and/or lipoxygenase to produce eicosanoids with mitogenic and with inflammatory properties [ 17 20 ] . Other possible antitumor actions include: induction of apoptosis, interference with hormone production, modulation of cellular signaling and gene transcription, and induction of differentiation [ 4 21 22 23 24 ] .
