Phospholipid

form within the biliary system, usually in the gallbladder where bile is stored and concentrated. Bile is a yellow-green substance containing bile salts, bile pigments, cholesterol, triglycerides, phospholipids, proteins and a wide variety of electrolytes. Though from all those substances, just phospholipids and bile salts help to the digestion of fats. (Marieb and Hoehn, 2015) A healthy adult is able to produce in a daily basis an approximate amount of 400-1100ml hepatic bile which is produced…

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…

For the purpose of this report we will be focusing mainly on the base level of cells, and those of an animal. Within all organisms we find cells, they form the life blood of their being. Cells contain the blue prints for all life forms known as D.N.A. Cellular structure While complex, cellular structures can also be relatively simplistic in design. Each component of the cell plays a vital role, working together in harmony to provide life. Initially we must look at the cell membrane. The cell…

 COMPOSITION OF MILK Milk is nearly complete natural food on the earth. It contains water, fat, protein, lactose and minerals as major constituents. The proportions of these constituents vary with species of the animal. For example, Mare’s milk contains only about 1.6% fat, while Reindeer’s milk contain 22.5% fat. Apart from this, the composition also varies with several other factors, viz., the breed of animal, the feeding pattern, season, lactation period, age of animal, environment, etc..…

Abstract Tafazzin, encoded by the TAZ gene, is a mitochondrial membrane-associated protein that remodels cardiolipin (CL), an important mitochondrial phospholipid. CL is essential for proper mitochondrial structure and function, ensuring proper functioning of energy production and apoptosis. TAZ mutations are associated with the X-linked metabolic disorder, Barth syndrome (BTHS). BTHS is a lipid metabolic disorder that affects mitochondria that is often fatal in infancy and early childhood, due…

Identifying the Presence of Macromolecules Using Benedict’s, Biuret’s, Sudan III, and Lugol’s Solution Betty Ngo Introduction Macromolecules are the critically important large molecules that fall into four main classes: carbohydrates, lipids, proteins and nucleic acids. Macromolecules are polymers which are built up by monomers. Monomers become polymers from the process dehydration reaction and polymers are broken apart by the process hydrolysis. Macromolecules are critically important…

Peroxisomes serve to produce hydrogen peroxide through oxidation, as well as break it down by converting it to water, or using the hydrogen peroxide to oxidize other organic compounds. They also produce energy by metabolizing fatty acids (Cooper, 2000). Peroxisomes execute various metabolic functions and create hydrogen peroxide as a byproduct from the process of oxidation. However, since the hydrogen peroxide created by the peroxisome is toxic, the organelle also produces an enzyme called…

The actual membrane is created up of phospholipids which naturally form a bilayer, these phospholipids have a head that are hydrophilic and two fatty acid tails that are hydrophobic, and this allows water molecules to pass between the phospholipid molecules by osmosis and allowed self-orientating properties. It’s more than just a passive envelope; it is a dynamic structure that is actively…

transport? The movement of molecules in passive transport travels with the concentration gradient (areas of high concentration to areas of low concentration). It does not need energy in the form of ATP. Facilitated diffusion moves substances across the phospholipid bilayer using transport proteins. Therefore, it does not require energy in the form of ATP, since the molecules in facilitated diffusion travels with the concentration gradient as…
