volume of heterotrophic microalgae than the photoautotrophic methods. Miao and Wu (2006) examined the strain of C. protothecoides and reported their lipid content as high as 55% compared to the autotrophic organisms at only 15% with analogous conditions.…

Module 5 Assignment: Fats (Lipids) 1. Steven is an IT manager who spends much of his day sitting at his computer. When he is home with his family, he enjoys watching his children play soccer and swim but rarely finds time to exercise himself. Steven’s doctor recently told him that his blood cholesterol levels are elevated. His blood lipids and other information about his medical history are given below: Sex: Male Age: 37 Family history: Mother had a heart attack at age 60…

is what distinguishes them. It has a sweet taste and is soluble in water. A nitrogen atom is present in amino acids but not in sugar molecules Elements found in lipids are hydrogen, oxygen, and carbon. Purpose The purpose in this lab is to determine the presence of certain macromolecules made by cells by detecting carbohydrates, lipids and proteins with four different indicators. Materials Test tubes Test tube rack Benedict's solution Iodine Biuret reagent White paper Hot water bath Vegetable…

Carbohydrates, lipids, proteins and nucleic acids are large biological molecules that play a major role in relation to the structure and function in plants and animals. These organic molecules consist of many examples and functions. Each biological molecule has a unique function and emergent properties that helps contribute to the cellular structure in both plants and animals. These biological molecules are known as macromolecules because they are large and are composed of thousands of atoms.…

formed. These complex molecules are macromolecules. Macromolecules are polymers, formed by dehydration synthesis. Dehydration Synthesis is when monomers are combines and water is removed. There are four types of macromolecules, carbohydrates, lipids, nucleic acids, and proteins. Carbohydrates are made up of carbon, hydrogen, and oxygen. With a structural components such as glucose and sugar. Carbohydrates can be singular molecules such as monosaccharides, or multiple molecules such as…

hydrophobic tails are buried within the membrane to avoid contact with water (Cooper, 2000). This arrangement represents the formation of cell membranes and is referred to as the lipid bilayer (Cooper, 2000). Because phospholipids are amphipathic molecules, meaning both water-soluble and water-insoluble, they can help lipids move back and forth across the cell membranes into the watery fluids on both sides (Cooper, 2000). This enables fat-soluble substances, including vitamins and hormones, to…

organic macromolecules which are essential to all life are carbohydrates, proteins, lipids, and nucleic acids.. These four organic macromolecules provide all cells with structure, create and store energy, and can be hormones, immune substances and genetic material. A macromolecule, or polymer, is a large complex molecule built from smaller molecules, or monomers, such as nucleic acids, proteins, carbohydrates, and lipids. Monosaccharides and polysaccharides are both carbohydrates.…

second messenger and regulator of apoptosis, stabilizes β secretase activity [36;36](He et al., 2010). In AD, increased CM levels regulate β and γ secretases and amyloid precursor protein (APP) processing on lipid rafts [69](Vetrivel et al., 2004). Mislocalization of β and γ secretase to lipid rafts in post Golgi rather than lysosomes can promote Aβ accumulation [69](Vetrivel et al., 2004). Sphingosine is associated with apoptosis and is elevated in AD brains [30](Hagen-Euteneuer et al., 2012).…

Biochemical tests are used to detect the presence of different kinds of organic molecules, carbohydrates, lipids, nucleic acids, and proteins. These tests include the Benedict’s Test, Iodine Test, Sudan III Stain Test, Biuret Test and many others. With these tests, the nutrients from an unknown solutions can be identified in the solution. The Benedict’s test is used for identifying reducing sugars, which are simple sugars that include monosaccharides and some disaccharides. The Benedict’s…

releases energy. Examples of macromolecules would be nucleic acids, proteins, and polysaccharides (2 or more sugars). The biological components are composed of starches, proteins, lipids, and nucleic acids. Starches consisit entirely of glucose monomers and are joined by glycosidic linkages, only found in plants. Lipids are a large group of biological molecules that…
