  • Homeostasis: Cell Membrane Proteins

    the organelles while eliminating wastes that could be harmful to them. The cell membrane is also known as the phospholipid bilayer because of the fact that there are two layers formed by phospholipid molecules. The phospholipid has a phosphate and a lipid portion. "The phospholipids lie with their hydrophilic heads at the membrane surface and their hydrophobic tails on the inside..." (Anatomy and Physiology Textbook 66) There are two general membrane proteins, including the integral proteins,…

  • Diabetes Mellitus (T1DM): A Case Study

    1.1 Background The World Health Organization (WHO) defines Type 1 Diabetes mellitus (T1DM) as insulin-dependent diabetes mellitus (IDDM) (1). A chronic autoimmune disease due to pancreatic dysfunctions leading to a decrease of insulin production. According to AACE Diabetes resource Centre T1DM is described as an autoimmune disorder that exhibits a catabolic function leading to a decrease in the plasma concentration of insulin and a compensatory elevated plasma glucagon and beta cell death that…

  • Carbohydrates Research

    m and n could be possibly different. Some biologists refer to carbohydrates as hydrates of carbon and they are technically correct. Alternately, there is no possible empirical formula that can describe lipids. Lipid must be identified experimentally. The broad definition is sometimes given to lipids as water insoluble organic compound usually located in biological organisms or systems. A variety of test for different substances would be done in this experiment. The Molisch test is not…

  • Macromolecules Lab Report

    experimental design for our project was to simulate the digestion of carbohydrates, lipids, and proteins. Using a certain medication called pancreatin we tested its effects on how it was able to break down these macromolecules. pancreatin is a mixture of pancreatic enzymes that help to aid in digestion; the enzymes that are present in this mixture include amylase (breaks down carbohydrates), lipase(breaks down lipids), and protease (breaks down proteins). We had set up trials for these enzymes…

  • Essay On Cosmetic Applications Of Inorganic Materials

    polymeric membrane, and nanospheres are composed of a cosmetic ingredient dispersed through a sphere (see above picture) [4]. Solid lipid nanoparticles (SLN) have also been found to be especially useful in the formulation industry. Solid lipid nanoparticles differ in their composition and preparation methods. In the most general terms they are composed of solid lipid, emulsifiers, and water/solvent [7]. They can be prepared by various techniques including, but not limited to, high shear…

  • Protein Molecules Essay

    atom. Carbohydrates can be traced back to photosynthesis. Take the form of starches, sugars and cellulose. They contain carbon, hydrogen, and oxygen like the lipids. Lipids include fats, oils, waxes, and sterols. Use the same elements as carbs. Made of glycerol and 3 fatty acids. (Triglyceride lipid) Steroids are a type of lipid Lipids include phospholipids that make cell membranes. Proteins are made of thousands of amino acids. Amino acids contain an amino group and carboxyl group. There are…

  • Meal Mix Up Lab Report

    see if the stomach content contains lipids or not.. This involved taking a piece of bag paper and using a pencil to divide it into five sections. Next, I labeled each section with the number of the stomach contents. Then, I placed two drops of each sample in the appropriate section. After, I set aside the paper and let it dry. Once it died I lifted up the paper to see which one I can see light through, if light shines through than the stomach content contains lipids. Thus, content two was the…

  • Body Fat Research Paper

    Lipids have a significant energy role, but also a fundamental role in the composition of the membranes of cells, nuclei, and nervous tissue. Focus on these fats and the foods that contain them. Edible fats Dietary fats should be present in the daily diet at 2-3 g / kg bodyweight per day (30-35% of total energy intake). But this rate is very easily exceeded because lipids are not always visible. The hidden fats are those that are contained in foods that do not appear fatty: meat, cold meats,…
