Lipid

Lipid rafts are defined as the subdomains of the plasma membrane that exist as distinct liquid-ordered regions of the membrane [1]. These membrane domains preferentially arise due to the interaction of specific lipids. They are mobile, dynamic and insoluble in non-ionic detergents such as Triton X-100 [2]. Lipid rafts are enriched in cholesterol, sphingolipids and phospholipids within cell membranes (Figure 1). Figure 1. Organization of lipid rafts (Note the higher concentration of cholesterol and

Production of Neutral lipid from algae Basanti L. and Gautieri P., 2014 states that the source of oil from algae biomass are lipids, these are classified as fatty acids and fatty acids derivatives, like Triacylglycerol’s, Wax esters, Phospholipids, phosphoglycerides and sphingomyelin, Isoprenoids (based on isoprene structure).The type of algal lipids that are convertible to biodiesel is the neutral type like triglycerides cholesterol though other types are like galactolipids among others are also

Dear Mr. Brown, I have received the result panel from your previous visit to check your lipids. We would like to share them with you. Test Result Triglycerides 145 mg/dL Cholesterol 210 mg/dL HDL 33 mg/dL LDL 160 mg/dL Triglycerides is the fat found in the blood and is used for energy. Having high levels of triglycerides can increase the risk for heart disease and could be a sign of metabolic syndrome (combination of high blood pressure, high blood sugar, low HDL, and high triglycerides). High

INTRODUCTION: Among several newer and promising new drug-delivery systems, liposomes represent an advanced technology to deliver active molecules to the site of action. They were first observed in late 1960. Their major purpose is to increase the therapeutic index of any drug and minimizing its side effects. Some of the anti-neoplastic agent are not able to reach at the therapeutic concentration at their site of action and some conventional drugs have a lot of side effect. One way to overcome this

Carbohydrates, Lipids or Proteins? Elizabeth Martin del Campo 20609008 Partner: April D’Souza TA’s: Avril Metcalfe & Quinton Yau BIOL 130L 005 Tuesday from 7:00PM to 9:50PM B2 149 Sept 22, 2015 INTRODUCTION The purpose of this lab is to determine the type of macromolecules that make up a particular unknown solution; using 3 different chemical tests. The first test consists of adding Benedict’s reagent to 12 different solutions; including the unknown. If any of the 12 solutions

The membrane around the cells in the body is the boundary that keeps them from reaching the surroundings on the outside. It allows for certain substances to pass through to the cells rather than others, and it contains proteins and lipids such as phospholipids (cholesterol) (Erster 3). The simplest membranes are known as a phospholipid bilayer, given that there are two layers containing hydrophilic heads and hydrophobic tails allowing the membrane to have its semipermeability. The tails on both layers

will be. But if the concentration of the ethanol is beyond a certain limit, it may break down the cell membrane to the point where there is in fact no overall effect as the ethanol would disturb the lipids in the membrane. Therefore, more of the red pigment in the beetroot would leak as the lipids control the substances that enter and leave the cell membrane. However the ethanol might also impair particular

How different temperatures effect the cell membrane of a beetroot Hypothesis: The more betalain is leaked when the membrane is in higher temperatures Abstract: The experiment which was conducted was to identify the effects of temperature of the beetroot discs. Majority of the pigment from the beetroot is found within the vacuole which is called anthocyanin and each of the vacuole is surrounded by a tonoplast membrane. Externally the cytoplasm is surrounded by the plasma membrane hence the foundation

The cell membrane surrounds the cytoplasm of a cell and is the barrier as to what can and cannot pass through the cell. The cell membrane acts as a barrier and is one of the many key factors for supporting life, without it diffusion and osmosis would not be able to occur. The barrier is selectively/partially permeable and regulates what enters and exits the cell, therefore facilitating the transport of materials needed for survival. There is two processes in which substances are carried across the

A large fraction of the phosphatidylcholine components of surfactant is Dipalmitoylphosphatidylcholine, which account for 70-80% of the surfactant lipid layer (Holm et al. 1996). Holm et al. determined that Dipalmitoylphosphatidylcholine is a disaturated phospholipid that has a liquid crystal transition temperature of 41* C - 42*C and exists in a rigid gel phase at body temperature which decrease
