Phospholipid

targeted to the skin but instead an antihistamine used to prevent balance related sickness, this might suggest why the use of the alternative lipid, DSPC, gave better results. For sample CIN14, (Table 8) that no cholesterol was used, observed the formation of crystals rather than functional liposomes and the most extreme drop in EE% of 28.33% (from 35.55% to 7.00%). This emphasises the requirement for some degree of fluidity for a membrane to be functional. As the presence of cholesterol is…

In the blood, cholesterols are parts of a molecular chain called Lipoproteins. These lipoproteins are found as droplets. Lipoproteins transport cholesterol throughout the body. Lipoproteins consists of cholesterols, lipids, phospholipids, and proteins. When one talks about "good cholesterol" verses "bad cholesterol", what one is actually talking about are one of two lipoprotein chains. A lipoprotein chain that has a high amount of proteins as compared to a lower amount of lipids…

Gallstones are formed when a chemical imbalance in the bile chemical makeup occurs and roughly effects about 10-15% of all Western adults.4 In the human body, the gallbladder produces bile which is made up of components of not only bile salts and phospholipids but also cholesterol. When the liver secretes an excessive amount of cholesterol or an increase consumption of salt and water, build up of cholesterol occurs in the gallbladder forming a gallstone. Often, gallstones are small enough to…

3.1 1. The improvements in the microscope help scientists see the cells better and distinguish the different organelles inside the cell. 2. Prokaryotic cells do not have a nucleus and most internal structures that eukaryotic cells. 3. This method builds on the work of early scientists by changing the soup broth with bacteria in it to a preserved petri dish. 4. Both cells and atoms are basic building blocks. 5. This poison would not kill bacteria because bacteria do not have a nucleus. 3.2 1.…

The SER plays an important role in the carbohydrate metabolism, synthesis of fats and phospholipids and in the detoxification drugs. The RER is very important for protein processing and is called rough because it contain ribosomes in its membrane (refer figure1). The double membranes of rough ER form sacs called cisternae. Insulin molecules…

Plasma lipids consist of triacylglycerols (16%), phospholipids (30%), cholesterol (14%), cholesterol ester (36%) and fatty acids free (4%). Lipids are transported in plasma lipoproteins (Figure 3). Four major classes of lipoproteins important are: chylomicrons, VLDL, LDL and HDL. Chylomicrons transport the…

It has a “thin murein layer surrounded by an outer membrane containing lipopolysaccharide and phospholipids, and they do produce a capsule. This rod-shaped bacterium is non-motile, non-spore forming, and about 0.5-1.0 μm in length”(Microbewikki). The bacterium has respiratory metabolism, but never performs fermentation. They are strict aerobes and uses…

The human body is made up of thousands of cells, each with a defined genetic program that allows them to work synchronically to regulate the metabolic and physiological processes required by the organism. All cells die (not accidentally), because in old age or because they are Cell death by apoptosis plays a crucial role in tissue development and homeostasis. This process is carried out through mitochondrial permeabilization and the activation of caspases. The condensation of chromatin and the…

Membrane Self-Assembly Processes: Steps Toward the First Cellular Life by Pierre-Alain Monnard & David W. Deamer Summary: To summarize, early cells must have had a membrane to encapsulate its components and keep them within the cell. This membrane was made up of amphiphiles. This membrane was very permeable and as a result, passive diffusion occurred. Later on this membrane evolved to be a little impermeable as to keep the metabolic reactions and catalysts that drive these reactions within…

Many things live in your mouth. Bacteria live in it. You ask, “What kinds of bacteria? Why can’t we sense it? Is it good or bad?” Be brave, take a reading adventure and find out answers to all these questions, and more. How much bacteria exactly? A lot of bacteria live in your mouth, colonies, and colonies. About 6 billion live in your mouth. That’s interesting because about 7.3 billion people live on earth. All those bacteria that live in your mouth actually live in diverse communities,…
