Posted by: | Posted on: November 27, 2020

26. It’s a good idea to have your cholesterol levels checked every few years, unless your doctor recommends more frequent checks. For example, lipids containing saturated fatty acids are solids at room temperature, whereas lipids containing unsaturated fatty acids are liquids. Content Filtrations 6. (a) 4 Mols of O2, (b) 3 Mols of O2, (c) 2 Mols of O2, (d) 1 Mole of O2. (a) Fatty acids, (b) Glycerol, (c) Both of the above, (d) None of the above. The excretion of ketone body in the urine in­volves the deficiency of, 101. (a) Digitonin, (b) Strobanthin, (c) Lycopyll, (d) Digi­talis. © 2005-2020 Healthline Media a Red Ventures Company. 1. Lipids are a naturally occurring group of substances that are not soluble in water but are freely soluble in organic solvents. Red blood cells have been very useful in the study of membranes and the protein components that provide structural support. As a result, energetically stable, large-scale assemblies of phospholipid molecules are formed in which the hydrophobic tails congregate within enclosed regions, shielded from contact with water by the polar heads (Figure \(\PageIndex{3}\)). Answer e. All of the options describe lipids. 22. The condition in which there is a high concen­tration of ketone bodies in tissues and _____________ is called_________. Previous question Next question Get more help from Chegg . Cholesterol is part lipid, part protein. True. Acetoacetate and p-hydroxyburate are readily oxidized by _____________ tissues; but acetone utiliza­tion is very _____________. 75. Niacin in the dosage of____________ thrice daily ________ cholesterol and triacylglycerol. 120. True B. Triacylglycerol is accumulated even in normal rate of fatty acid synthesis by the deficiency of. Here are the typical goals for lipid levels: However, rather than focusing on specific numbers, your doctor may recommend a variety of lifestyle changes to help lower your overall risk for heart disease. 104. Gaucher’s disease is caused by the deficiency of the enzyme _____________. (a) 5-membered ring, (b) 6-membered ring, (c) 8- membered ring, (d) None of the above. molestie consequat, ultrices ac magna. Both glycoproteins and proteoglycans contribute to the carbohydrate layer on the surface of the cell. Lipids serve numerous and diverse purposes in the structure and functions of organisms. Figure 2 depicts a typical phospholipid composed of two fatty acids linked to glycerol (a diglyceride). IDL is formed when _____________ is largely removed by the action of . The rate of fatty acid oxidation is increased by. (a) Nervonic acid, (b) Hydroxynervonic acid, (c) Cerebronic acid, (d) Lignoceric acid. Serum LDL has been found to be increased in. 22. Cholesterol is more soluble in water than a triacylglyceride or a phospholipid. Fatty acid oxidation captures high-energy phos­phate as 48 per cent. Because the long hydrocarbon chain, fatty acids are hydrophobic (“water fearing”) or nonpolar. Phospholipid Bilayer. Fourteen prostaglandins have been isolated from male reproductive tract. Explain why fatty acids with hydrocarbon chains that contain only single bonds are called saturated fatty acids. High; Polyunsaturated; Monounsaturated. 106. Choline is the most important__________ agent. MEMORY METER. 49. A. hydrophilic Glycolipids lack the glycerol component found in phospholipids. 81. The number of__________ of KOH required to neu­tralize Igm. When applied directly to the skin, it can reduce inflammation and temporarily relieve minor skin irritations, itching, and rashes by reducing the secretion of histamine, a compound produced by cells of the immune system in response to the presence of pathogens or other foreign substances. 111. Waxes contain esters formed from long-chain __________ and saturated __________, and they may also contain substituted hydrocarbons. 51. Since then, researchers have developed a more complex formula for this calculation. Practice. 11. 29. Triglycerides are classified as simple lipids because they are formed from just two types of compounds: glycerol and fatty acids.In contrast, complex lipids contain at least one additional component, for example, a phosphate group (phospholipids) or a carbohydrate moiety (glycolipids).Figure 2 depicts a typical phospholipid composed of two fatty acids linked to glycerol (a diglyceride). 116. 12. Copyright 10. Essential fatty acids effect the prolongation of clotting time and increase fibrinolytic activity. Which one of the following statements is true? One of the most prominent bacteria that feed on lipids is Propionibacterium acnes, which uses the skin’s lipids to generate short-chain fatty acids and is involved in the production of acne. Gaucher’s disease is characterized specially by the increase in. Which lipid is most plentiful in the cell membrane? Hydrocortisone is a synthetic form of cortisol, a corticosteroid hormone produced in the adrenal glands, from cholesterol. Compare and contrast triacylglycerides (triglycerides) and phospholipids. Carrier protein; squalene and sterol carrier protein. Cholesterol is actually part lipid, part protein. Phospholipase A2 catalyzes the hydrolysis of the ester bond in position 2 of glycerophospholipids to form sphingosine. Linoleic acid; Linolenic acid; Arachidonic acid. Prostaglandin endoperoxide synthase catalyze. In chylomicrons the predominant lipid is _____________. 52. This is why the different kinds of cholesterol are called lipoproteins. Which one of the following adjustments might the bacterium make to maintain the same level of membrane fluidity? Choline is synthesized using labile ______________ groups donated by__________ in the process of transmethylation. (a) Linoleic acid, (b) Linolenic acid, (c) Arachidonic acid, (d) All of the above. The structural integrity of cell surface and sub­cellular particles are maintained by lipoproteins. Peroxides are formed at the double bonds of unsaturated fatty acids by oxidation when ex­posed to air. The substances that prevent the accumulation of fat in the _____________ are known as _____________.
