Extract of sample "Hyperlipidemia and Membrane Composition"

As mentioned earlier that the lipids are an important component of the cell membranes, they are also affected by an increase or decrease in the amount of circulating lipids in the body. The increased amount of lipids in the body leads to an increased number of fatty acids. These increased free fatty acids are taken up by cell membranes of many cells of the body, the most important of which are erythrocytes, immune cells, and platelets. The increased fatty acid content of the cell membrane helps to retain its fluidity of the membrane but, on the other hand, it also affects the enzymatic activity of the membrane due to oxidative damage to membrane proteins (Fatty acids: physiological and behavioral functions, 2001). The alteration in the structure and function of erythrocyte due to increased incorporation of fatty acid was found to be a cause of their hemorheological behavior leading to many diseases. The major protein channel affected by this was the Na-K ATPase transporter (Koter M et al, 2004).
Atherosclerosis, a diseased characterized by increased aggregation of platelets was also found to be caused by increased lipid content of the body. The increased amount of arachidonic acid in the platelet cell membrane was thought to be a cause of this increased platelet aggregation (omega-3 fatty acids and health, 1995).
Apart from all the adverse of hyperlipidemias on membrane composition and function, they have been found to be rather helpful in patients with epilepsy. Increases lipid content decreases one’s susceptibility to seizures as increased fatty acids in the membrane affect the protein channels leading to decreased firing capacity of neuronal and glial cells (Fatty acids: physiological and behavioral functions, 2001).

...Hyperlipidemia and Membrane Composition... Hyperlipidemia and Membrane Composition... the impact of solute concentration on the rate of osmosis Introduction: Osmosis is defined as the movement of water molecules through a selective membrane (Freeman, 2010). Osmosis occurs so as to balance the water potential on either side of the membrane. Water potential is used to describe the tendency with which water moves from one region to another. This experiment was carried out in order to determine how the rate of osmosis changes under different solute concentrations. Solute concentrations heavily influence how osmosis occurs. In animal cells, when the solute concentration is equal on both sides of the membrane, there will be no movement of water...

Membrane and Diffusion Introduction The interior of the cells is separated from the outside by a membrane known as a cell membrane whose permeability to ions and organic molecules are selective[Yos07]. The cell membrane controls the move movement of molecular particles in and out of the cell and its main function is protecting the cell from its surrounding. The cell membrane is mainly composed of the lipid layer embedded with proteins and it’s involved in the following cellular processes: Signaling of the cell, Adhesioning of the cell and conductivity of the ions in the cell and it forms the external attachment of cells interior to the extracellular structures wh...

It allows me to get a dose of the cool breeze of San Francisco while getting a closer look at the happenings in its alleys. I always see a bunch of young people chatting while sipping espressos in a coffee shop everyday. In my night out with friends, the presence of young people is more dominant at the bars; they puff on cigarettes as adults do. Caffeine for the day and nicotine at night; these are indeed part of everyday life in America and elsewhere in the world. To some, these substances have become a necessity. Caffeine and nicotine stimulate the body and eases drowsiness and tension, but these are...

I might have picked up this notion from school where students with homosexual orientation were considered ‘weirdoes’ and good kids were supposed keep themselves away from them. I got to know about gay marriages when our neighboring apartment was occupied by a gay couple, who were legally married. At first, the idea seemed ludicrous to me, but as time passed I came to know of the real issues of sexuality and marriage. With the help of my broadminded parents and real life experiences, my antagonistic attitude to homosexuality and gay marriages has changed altogether. Now I und...

Glomerular basement membrane diseases

...Hyperlipidemia and Membrane Composition... Hyperlipidemia and Membrane Composition... Basement Membrane Diseases Glomerular basement membrane or GBM is an important membrane of the glomerulus that forms the boundary between blood and urine. It consists of a central thick electro-dense layer known as lamina densa surrounded by 2 thin peripheral layers, the lamina rara interna and lamina rara externa. The constituents that make up the membrane are type- 4 collagen, laminin, polyanionic proteoglycans, fibronectin, entactin and several other glycoproteins and collagen (Alper, 2007). The main supra structure is formed by type- 4 collagen to which other glycoproteins attach (Kang et al, 2006).   NORMAL GBM. LEFT - a single glomerulus. There are one mill...
