Omega-3 fatty acids from marine and plant sources provide a wide range of benefits in several human healthconditions. In vivo studies indicate that omega-3 fatty acids influence the course of several human diseases, including thosethat involve abnormal immune function, mental disorders, and genetic abnormalities in lipid metabolism. Omega-3 fatty acidsare taken up by virtually all body cells and affect membrane composition, eicosanoid biosynthesis, cell signaling cascades,and gene expression. These fatty acids are especially important during human brain development; maternal deficiency ofomega-3 fatty acids may lead to several neurological disorders. The review highlights recent findings on omega-3 fatty acids’influence on autoimmune diseases, mental health, and gene expression.

The omega-3 polyunsaturated fatty acids have a wide range of beneficial effects in several human health pathologies. Laboratory animal and in-vitro studies have indicated that omega-3 fatty acids affect blood lipid profiles, cardiovascular health, membrane lipid composition, eicosanoid biosynthesis, cell signaling cascades and gene expression. Findings from epidemiological studies suggest that intake of n-3 fatty acids from natural sources or supplements may influence the onset and progression of several disease states including cardiovascular disease and cancer. This review highlights some recent findings in health research that advance our understanding of how omega-3 fatty acids influence cardiovascular health and cancer development.
Phenolic Compounds in Plant Foods : Chemistry and Health Benefits
Marian Naczk,Fereidoon Shahidi 한국식품영양과학회 2003 Preventive Nutrition and Food Science Vol.8 No.2
Phenolic compounds in food and plant materials belong to the simple phenols, phenolic acids, coumarins, flavonoids, stilbenes, tannins, lignans and lignins, all of which are considered as secondary plant metabolites. These compounds may be synthesized by plants during normal development or in response to stress conditions. Phenolics are not distributed uniformly in plants. Insoluble phenolics are components of cell walls while soluble ones are present in vacuoles. A cursory account of phenolics of cereals, beans, pulses, fruits, vegetables and oilseeds is provided in this overview. The information on the bioavailability and absorption of plant phenolics remains fragmentary and diverse. Pharmacological potentials of food phenolics are extensively evaluated. However, there are many challenges that must be overcome in order to fully understand both the function of phenolics in plant as well as their health effects.

Purification and Characterization of a Collagenolytic Protease from the Filefish , Novoden modestrus
Kim, Se Kwon,Kim, Jong Bae,Park, Pyo Jam,Shahidi, Fereidoon 생화학분자생물학회 1998 BMB Reports Vol.35 No.2
A serine collagenolytic protease was purified from the internal organs of filefish, Novoden modestrus, by ammonium sulfate, ion-exchange chromatography on a DEAE-Sephadex A-50, ion-exchange rechromatography on a DEAE-Sephadex A-50, and gel filtration on a Sephadex G-150 column. The molecular mass of the filefish serine collagenase was estimated to be 27.0 kDa by gel filtration and SDS-PAGE. The purified collagenase was optimally active at pH 7.0-5.0 and 55℃. The purified enzyme was rich in Ala, Ser, Leu, and De, but poor in Trp, Pro, Tyr, and Met. In addition, the purified collagenolytic enzyme was strongly inhibited by N-P-toluenesulfonyl-L-lysine chloromethyl ketone (TLCK), diisopropylfluorophosphate (DFP), and soybean trypsin inhibitor.

A serine collagenolytic protease was purified from the internal organs of filefish Novoden modestrus, by ammonium sulfate, ion-exchange chromatography on a DEAE-Sephadex A-50, ion-exchange rechromatography on a DEAE-Sephadex A-50, and gel filtration on a Sephadex G-150 column. The molecular mass of the filefish serine collagenase was estimated to be 27.0 kDa by gel filtration and SDS-PAGE. The purified collagenase was optimally active at pH 7.0-8.0 and $55^{\circ}C$. The purified enzyme was rich in Ala, Ser, Leu, and Ile, but poor in Trp, Pro, Tyr, and Met. In addition, the purified collagenolytic enzyme was strongly inhibited by N-P-toluenesulfonyl-L-lysine chloromethyl ketone (TLCK), diisopropylfluorophosphate (DFP), and soybean trypsin inhibitor.
Characterization of Acid- and Pepsin-soluble Collagens from Flatfish Skin
허민수,Jae Hyoung Lee,Hyung Jun Kim,Seong Joon Jee,Jung Suck Lee,You-Jin Jeon,김진수,Fereidoon Shahidi 한국식품과학회 2010 Food Science and Biotechnology Vol.19 No.1
Acid-soluble collagen (ASC) and pepsin-soluble collagen (PSC) from flatfish skin were characterized. The yield of PSC was 85.5%, which was higher than that of ASC at 57.3%. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) patterns showed that both the ASC and PSC were consisted of α1 and α2 chains, and β-chain. According to the results of Fourier transform infrared (FTIR) spectroscopy and hydroxylation, no difference in the helical structure between ASC and PSC was found. Thermal denaturation temperature (TDT) of flatfish skin collagen was 26.6℃ for ASC and 26.7℃ for PSC, which were similar to those of temperate fishes, while were lower compared to tropical fishes, such as the conger eel and Nile perch. There was no solubility difference between ASC and PSC at various pH and NaCl concentrations. Therefore,PSC will be preferable compared to ASC for commercial uses because of its higher yield.
