Reactive Oxygen Species Essay -- Biology, Lipids, Proteins, DNA

The formation of re alert oxygen species (ROS) is an unavoidable outgrowth in aerobic organisms as by products during metabolic respiration (Han et al., 2007, Je et al., 2009). These extremely re expeditious ROS can be considered as strong oxidants and have been shown to bring out damage in all cellular macromolecules, such as lipids, proteins and DNA. everywhere the years dietary polyphenols have been widely studied for their biologic activities including antioxidant bodily function (Ahn et al., 2007, Heo et al., 2009, Kang et al., 2005, Li et al., 2009). Polyphenolic compounds be naturally occurring compounds containing phenolic functionality and this large diverse root word of secondary metabolites are exist both in terrestrial and aquatic environments (Shibata et al., 2002, Susanto et al., 2009). Beside the strong antioxidant properties, these naturally occurring polyphenols are known to have numerous biological activities such as anti inflammatory (Ryu et al., 2008), a nti allergic (Lee et al., 2009), anti bacterial (Al-Mola, 2009, Suffredini et al., 2004), anti-plasmin inhibitiory (Fukuyama et al., 1990), matrix metalloproteinase inhibitory (Kim et al., 2006) and anticancer (Kong et al., 2009). The high antioxidant power of polyphenols is loosely believed to responsible for these activities. Therefore it is very clear that the possibility of use this active compounds in many industrial applications as functional ingredients. Phlorotannins (brown algal polyphenols) are polyphenolic compounds found exclusively in brown seaweeds. Phlorotannins, a sub congregation of tannins, are produced only if by polymerization of phloroglucinol units (Kang et al., 2007, Koivikko et al., 2005). During last two decades, the roles and functions of phlorotannins have been ... ... available proteases and carbohydrases. barely they reported that Alcalase and Viscozyme extractes were more effective than the other extracts tested. With these significant results it is clear that EAE affords sizable advantage over commonly used classical extraction technique. taken together, enzyme treatment previous to extraction has resulted in improved yields in the fountain of bioactive components from seaweeds. In all instances mentioned above, hydrolytic enzymes have been used in different combinations as agents that interact on cell walls, breaking down the structural rightfulness rendering the intracellular materials more exposed for solvent extraction. Since EAE has attracted growing please in the extraction of biologically active components, the technique could be explored as a mean to enhance the extraction of particular metabolites from seaweeds. Reactive atomic number 8 Species Essay -- Biology, Lipids, Proteins, DNAThe formation of reactive oxygen species (ROS) is an unavoidable force in aerobic organisms as by products during metabolic respiration (Han et al., 2007, Je et al., 2009). These super reactive ROS can be considere d as strong oxidants and have been shown to perplex damage in all cellular macromolecules, such as lipids, proteins and DNA. over the years dietary polyphenols have been widely studied for their biological activities including antioxidant activity (Ahn et al., 2007, Heo et al., 2009, Kang et al., 2005, Li et al., 2009). Polyphenolic compounds are naturally occurring compounds containing phenolic functionality and this large diverse group of secondary metabolites are exist both in terrestrial and aquatic environments (Shibata et al., 2002, Susanto et al., 2009). Beside the strong antioxidant properties, these naturally occurring polyphenols are known to have numerous biological activities such as anti inflammatory (Ryu et al., 2008), anti allergic (Lee et al., 2009), anti bacterial (Al-Mola, 2009, Suffredini et al., 2004), anti-plasmin inhibitiory (Fukuyama et al., 1990), matrix metalloproteinase inhibitory (Kim et al., 2006) and anticancer (Kong et al., 2009). The high antioxidant power of polyphenols is mainly believed to responsible for these activities. Therefore it is very clear that the possibility of use this active compounds in many industrial applications as functional ingredients. Phlorotannins (brown algal polyphenols) are polyphenolic compounds found exclusively in brown seaweeds. Phlorotannins, a subgroup of tannins, are produced entirely by polymerization of phloroglucinol units (Kang et al., 2007, Koivikko et al., 2005). During last two decades, the roles and functions of phlorotannins have been ... ... available proteases and carbohydrases. just they reported that Alcalase and Viscozyme extractes were more effective than the other extracts tested. With these significant results it is clear that EAE affords gargantuan advantage over commonly used classical extraction technique. taken together, enzyme treatment previous to extraction has resulted in improved yields in the graphic symbol of bioactive components from seaweeds. In all instan ces mentioned above, hydrolytic enzymes have been used in different combinations as agents that interact on cell walls, breaking down the structural honor rendering the intracellular materials more exposed for solvent extraction. Since EAE has attracted growing bear on in the extraction of biologically active components, the technique could be explored as a mean to enhance the extraction of particular metabolites from seaweeds.
