Fatty Acid Elongation Service

Online Inquiry


Longer chain fatty acids is very important for cells. Although longer chain fatty acids are derived from either dietary sources or from elongation of C16-CoA or C18-CoA formed by the cytoplasmic fatty acid synthetase system, all of the fatty acids needed by the body can be synthesized from palmitate (C16:0) except the essential, polyunsaturated fatty acids like linoleate. Elongation of fatty acids could happen at endoplasmic reticulum in which fatty acid molecules of length up to C24 may be produced. Mitochondrial elongation could lead to fatty acids up to C16 in length. Fatty acid elongation in mitochondria is essentially the reverse of beta-oxidation for fatty acid oxidation. Particularly, both pathways make use of acetyl-CoA acyltransferase, 3-hydroxyacyl-CoA dehydrogenase and enoyl-CoA hydratase. Any step in these pathways will impair the function of cell. A series of studies have shown that abnormal fatty acid elongation causes several pathologies like neuronal ceroid lipofuscinosis and fundus flavimaculatus. In Creative Proteomics, we provide reliable, rapid and cost-effective fatty acid synthesis related service to speed up your research aims ranging from diseases diagnosis to gaining new insights in disease mechanism or treatment.
