  • Lipid Extraction Essay

    The major bottleneck for lipid extraction from the wet microalgae is the low extraction efficiency, because of the immiscibility of nonpolar organic solvents with water contained in wet microalgae {Yoo, 2012 #31} {Kim, 2013 #118}. Traditional method for lipid extraction from dry biomass uses a co-solvent system, which consist of a non-polar solvent and polar solvent {Halim, 2012 #7} {Kim, 2013 #118}. When the co-solvent system is directly applied to wet microalgal biomass, the microalgal cells tend to stay in the hydrophilic phase because of their negatively charged surface, limiting the direct contact between hydrophobic extraction solvents and the microalgal cells {Huang, 2013 #1} {Yoo, 2012 #31} {Kim, 2013 #118}. Therefore, the drying process…

  • Viral Pathogens Essay

    Viral pathogens use liver cells to replicate, then attach to their lipid droplets to to accumulate, assemble and bud off into the rest of the body. Liver produces and secretes LDL, VLDL and HDL which are taken up by every cell in the body that uses cholesterol, including the liver cells that take them up too.2 Viruses hijack these lipoproteins and use them to get into the liver cells, where they replicate, which opens up a gateway to the rest of the body. They replicate within the endoplasmic…

  • Lipid Oxidation Essay

    1.3.3 Lipid oxidation While not a direct outcome of proteinaceous compounds, aldehydes such as hexanal and (E)-2-nonenal have been attributed to the oxidation of lipid components present in the raw material (Aaslyng et al., 1998b). They are often present in much higher concentrations in enzyme hydrolysates and have been correlated to beany off-odours described in numerous literature. Solina et al. (2005) compared the volatile components of soy protein isolate (SPI) and acid-hydrolysed soy…

  • Lipid Biochemistry

    Lipids are fatty acids and their derivatives, and substances related biosynthetically or functionally to these compounds. Lipids are diverse group of organic compounds including fats, oils, hormones, and certain components of membranes that are grouped together and mainly amphipathic. The variation in head groups and aliphatic chains allows the presence of more than 1000 different lipid species in any eukaryotic cell. Different types of lipid include Phospholipids, Sphingolipids and…

  • Lipids Research Paper

    Lipids: Lipids have a hydrophobic nature because of the predominantly of hydrocarbon chains in their structure. They are insoluble or poorly soluble in water, but readily soluble in non polar solvents such as ether and benzene. Characteristics of Lipids:  Amphiphatic  Naturally occurring  Soluble in organic solvents but insoluble in water  Undergo saponification  Undergo emulsification Classification and biological functions of Lipids: • Fatty Acids:  Energy sources  Biosynthetic…

    phospholipid head groups and the hydrophobic residues on the peptides with the hydrophobic core of the membrane 3) pore formation and micellization of the lipid bilayer occurs, leading to disintegration of the membrane allowing leakage of essential nutrients and ions, followed by complete cell lysis.[1][4] In the barrel-stave mechanism, α-helical peptides form transmembrane pores with their hydrophobic parts in contact with the external lipid environment and hydrophilic parts pointing inwards…

  • Dietary Lipids Essay

    General Introduction Dietary lipids: Dietary lipids consist of a broad group of compounds that are soluble in organic solvents and insoluble in water. Their density is lower than water and consistency varies from liquids to solids at normal room temperature, depending on their structure and function. They are also referred as ‘Oils’ which are liquid and ‘fats’ which are solid at room temperature. Lipids are the important constituents of diet due to their higher energy value. One gram of lipid…

  • Tpk-Trypsin Lab Report

    Culture Infective Dose (TCID50) will be used. In TCID50 serial dilutions from the supernatant of the infected cells will be used to cause cytopathic effects (CPE) on MDCK cells. The TCID50 will be lower in case of viperin-transfected cells compared to the negative control ones. Objective 3: Investigate the effect of viperin on the cell lipid rafts and investigate the IAV release from the cells in the presence of duck viperin. Human viperin inhibits FPPS, which inhibit the formation of lipid…

  • Ambulanc Lipids: A Case Study Essay

    Lipids are more commonly referred to a fats. They are used for energy and cell structure. There are multiple types of fats, including saturated fats, unsaturated fats, polyunsaturated fats, and phospholipids. Saturated fats, unsaturated fats, and polyunsaturated fats are used for energy because they store large amounts of it. Phospholipids are used for cell structure. Proteins are the final organic compound. They are made up of amino acids that are chained together. Since there are 20 types…

  • Lipids In Milk Lab Report

    purpose of this lab was to identify the lipids in an egg yolk and to identify the amount of lipids in milk [1]. To extract the lipids from the egg yolk, the egg yolk needed to be combined with an organic solvent such as a mixture of CHCl3/MeOH. An organic solvent was needed to carry the extracted lipids up the TLC plate because the plate was polar, due to the presence of silica gel (silanol groups). To compare relatively similar lipids to the ones found in the egg yolk, the egg yolk extract was…
