All About Lipids
Lipids

1. What is your macromolecule made of? List element names and/or other molecules. a. Lipids are mostly composed of carbon, hydrogen and oxygen. Other elements, such as nitrogen and phosphorus can be found also. Molecules found in lipids include fats, waxes, sterols, and fat-soluble vitamins.

2. Include 2 examples of your macromolecule and their purpose in your body. a. An example of a lipid is steroids. Steroids are taken to increase the hormone testosterone, which helps to build muscles. Another example of a lipid is phospholipids. These are a class of lipids, and also a huge part of your cell membranes. They have quite a few roles in our body, such as helping an unborn babies lungs develop. 3. Find out where in the human body your macromolecule is found. Be specific. If it is found in cells, explain where it is in the cell and what is does for the cell.
a. Lipids make up the cell plasma membrane and the nuclear membrane. Steroids are also lipids, and they are hormones that act as signaling molecules. You can find lipids in all cells in your body because they make up the hydrophobic part of the phospholipid membrane.

4. List two foods in which your macromolecule is found in large amounts.
a. Cheese burgers from McDonalds contain an extremely high amount of cholesterol, which is a lipid.

b. This small entre may not seem very unhealthy, but it happens to be on America’s top 10 most unhealthy foods! This empanada is one of the most fatty deserts around. Fat is a molecule found in lipids.

5.How does your macromolecule affect your life? Be very specific about two ways it helps humans and one way it can hurt humans.
a. Lipids are a necessity in life and if you don’t have them, you cannot survive. On the other hand, if you eat too many it can lead to death because of the build up of fats. One way it can hurt humans is if the build up of lipid storage in places like liver can cause irreversible damage to the body and may

    Lipids are long aliphatic hydrocarbon chains which are either branched or unbranched that can form rings and may have unsaturation. [8] They are products of animal or vegetable origin which are extracted with either ether, chloroform, benzene, petroleum, carbon disulfide. [6] They can be described as substances which are insoluble in water but soluble in fat solvents. [5] Lipids are compounds that share properties based on their structural similarities mainly a preponderance of nonpolar groups. [4] It includes compounds such as fatty acids, glycerolipids, sphingolipids, terpenes, steroids and carotenoids. [7]…

    Abstract: The experiment was about the characterization of a fat/oil sample through three tests, namely the grease-spot test, saponification test, and unsaturation test. The procedures include the use of a filter paper divided into four sections and a drop of vegetable oil in a section; the same was done on lecithin, dichloromethane, and water and was heated. Oil, fat, and water were subjected into a saponification test using NaOH, and acidification using concentrated H2SO4. And lastly, oil, fat and glycerol were subjected into an unsaturation test by adding dichloromethane, and was added with a 5% Bromine-dichloromethane solution, the total volume of the 5% Br-DCM solution was then obtained.…

    1. Lipids are made up of 3 fatty acids and a glycerol molecule, referred to as a triglyceride. Glycerol is an alcohol with 3 hydroxyl groups (OH). A fatty acid attaches itself to each hydroxyl group with the elimination of 3 water molecules (condensation). The fatty acids vary and determine the properties of a lipid.…

    Lipids are a group of diverse fatty or oily substances that are grouped together because they are insoluble in water and are soluble in so-called fat solvents (diethyl ether, acetone, hexane and carbon tetrachloride). The elements present are carbon, hydrogen, and oxygen which are combined as esters of various fatty acids with the tri-hydroxy alcohol, glycerol. There are many different categories of lipids like triacyglycerols, phospholipids and steroids and each category has different components present in its structure. In this experiment, fatty acids are prioritized. Fatty acids are components of many types of lipids. Fatty acids are carboxylic acids with very long hydrocarbon chains, usually 12-18 carbon atoms long. Even though these carboxylic acids can hydrogen bond with water, they are insoluble…
