  • Staphylococcus Aureus Research Paper

    Staphylococcus aureus is responsible for various types of infections including skin and also respiratory tract infections. S.aureus can infect tissue when if the defensive line such as the skin or mucosal barriers had been breached. The infection caused by this bacteria can be spread in different modes such as direct contact from an infected wound, contact with the hyaluronidase, an enzyme produced by the bacteria that destroys tissues or even skin to skin contact with an infected person.…

  • Macromolecules

    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…

  • Subterranean Ecosystems

    regulation (Hervant et al, 1999; Caruso et al, 2008). Lipids play an important role as reserves in cave adapted amphipod N. virei. When N. virei and N. rhenorhodanensis were starved for 6 months, N. virei depleted lipids to a greater extent from initial content (63.2%) followed by carbohydrates (50.9%) and proteins (34.5%), whereas interstitial N. rhenorhodanensis used all of its carbohydrates reserves (94.4%) followed by proteins (52.5%) and lipids (41.9%). In epigean amphipod Gammarus…

  • Barrier Of Skin Essay

    protection, sensation, temperature and damage as to make sure skin maintain in good condition. Study have been carried out on microscopic structure of skin where layer of epidermis which stratum corneum play an important role in hydration and its lipid maintaining skin hydration by preventing evaporation of water from skin or in other word it hold moisture of skin. As mention before, epidermis which is the outermost layer of skin which characterized by thin, tought ,waterproof and also play role…

  • Fat In Milk

    Information Lipids, a broad term referring to fats and oils, are incredibly important in the human diet. “[Lipids] store more than twice as much energy as carbohydrates in a given weight, and so are a much more efficient supply.” (McGee) Lipids have many functions, they aid in cell growth, help transmit inflammatory and other signals, as well as making up most of the cell membrane. They…

  • Macromolecules In Biology

    are composed of nutrients. Nutrients are chemical substances essential for survival because they provide energy and raw materials and support body processes such as growth, maintenance, or repair of tissues. These nutrients include Carbohydrates, lipids, and proteins which are three macromolecules that play important roles in nutrition and digestion. There are two types of Carbohydrates, simple and complex. Carbohydrates are commonly called sugars and provide the major source of fuel to power…

  • Essential Nutritional Contents Of The Food Label

    molecules have essential functions like as source of energy, materials for building new body mass such as muscles, and other molecules with essential functions like hemoglobin, which carries oxygen in the blood. These biomolecules are carbohydrates, lipids, proteins and nuclei acids. Biomolecules are called polymers (large molecules) which are composed of smaller molecules known as monomers. 11.1 Elements Present in Biomolecules Biomolecules are organic compounds, thus they are composed…

  • Essay On Prokaryotic And Eukaryotic Cells

    I. The most basic unit of life is the cell. All living things are composed of cells. Cells may only from through a process of division and replication of previously existing cells. Cells are microscopic; however their structure is complex. All types of cells possess a plasma membrane which separates its contents from its surroundings. . There are two types of cells: prokaryotic and eukaryotic. a. Prokaryotic cells are simpler than eukaryotic cells. Within prokaryotic cells are bacteria cells…

  • Rancidity Of Cooking

    molecules and for easier absorption of nutrients by our guts. However, heating oil repeatedly with the presence of air, for certain period of time, might cause undesired chemical changes within the chemical characteristics of the oils, for example lipid oxidation, which is responsible for rancidity. The word “rancid” is used to describe the unpleasant odor and flavour produced by decomposing oils or fats. In the food industry, antioxidants normally act as food additives and are added in oils to…

  • Synthesis Process Of Macromolecules

    the fresh information, the Dehydration Synthesis process and the Macromolecules. I’ll start with the Macromolecules. These molecules are the four molecules all living things need to survive. The four molecules are Proteins, DNA, Carbohydrates, and Lipids. Each of these molecules is made of Carbon, Hydrogen, and Oxygen at the very least. Proteins have Nitrogen as an added element, and DNA has Phosphate and Nitrogen. The base structure of each molecule has a carbon skeleton. This means that…
