Determination of Ffa and Iodine Value

Also to determine the molar mass of an unknown solid acid by titration with standardized NaOH solution. First we prepared NaOH solution and standard acid. Measure appropriate amount of 6 M NaOH. Transfer to 500 ml volumetric flask. Use deionized water to fill the 500 ml flask. Then transfer it to plastic Erlenmeyer flask. Same thing with the acid but use 250 ml volumetric flask. Weight appropriate amount of oxalic acid dehydrate, transfer and mix it with deionized water in 250 ml volumetric flask. Transfer this standard acid solution to a 250 ml plastic Erlenmeyer flask. After that standardization of NaOH by titration. Take 15-20 ml of the acid into 250 ml glass and add 2 or 3 drops of phenolphthalein. Add NaOH with constant swirling until the acid solution change into pink. Record the final and initial volume used in

Unsaturated fatty acid not filled with all the hydrogen it can hold. Because of that, it's less thick and less dense like liquid oil. Monounsaturated fat has one empty spot. Examples of monounsaturated fat include plants base liquid oil which contains olive oil and peanut oil

Over the course of three days, the intake of daily foods was documented in the iProfile food journal tracking system. The iProfile provides information on a nutritional analysis report that examines the macronutrients of carbohydrates, proteins, and fats when measured to the Recommended Dietary Intake (RDI) for overall health. The results will provide data to determine if the individual is consuming the recommended nutrients for strength, their metabolism, and to ensure that other body components are functioning.

The fatty acids are then purified by distillation and neutralized with an alkali to produce soap and water. The fats and oils used in soap-making come from animal or plant sources. The four basic soaps used in this procedure were made using olive oil, vegetable oil, vegetable shortening, and lard. Each fat or oil is made up of a distinctive mixture of several different triglycerides. In a triglyceride molecule, three fatty acid molecules are attached to one molecule of glycerin. There are many types of triglycerides; each type consists of its own particular combination of fatty acids. They are weak acids composed of two parts: A carboxylic acid group consisting of one hydrogen (H) atom, two oxygen (O) atoms, and one carbon (C) atom, plus a hydrocarbon chain attached to the carboxylic acid group. Generally, it is made up of a long straight chain of carbon (C) atoms each carrying two hydrogen (H) atoms. The carboxylate end of the soap molecule is attracted to water. It is called the hydrophilic end; this end of the fatty acid chain prefers water. The hydrocarbon chain is attracted to oil and grease and is the hydrophobic end. However, when soap is presented to hard water which is water containing minerals, such as calcium, magnesium, and seldom minerals like iron. Soap produces what is known as soap scum, or residue from the

Doctors use Iodine-131. Iodine-131 can be used to treat someone with hyperthyroidism. It can also be used to treat thyroid cancer. It can also be used as a type of medical imaging.

Iodine is an indicator for starch. When iodine is merged with starch, it turns a dark purple/black color.

Unsaturated fatty acids are characterized with having at least one carbon double bonded with another carbon, losing the normal bond with hydrogen and the corresponding hydrogen. The number of double bonds, hydrogens, and carbons differ in structure of different types of fatty acids and cause the difference in function between the fatty acids. But even though most fatty acids are different from each other due to structure and function, all unsaturated fatty acids do have some things in common. They all enter the cell via the membrane and increase the fluidity of the plasma membrane, increasing overall cell health, and they all form unsaturated fats [3]. Unsaturated fats are made up of many different strands of different types of fatty acid. The type of unsaturated fatty acid I will be talking about today is an omega-3 fatty acid made up of three different types of fatty

The iodine test results can be recorded after mixing the iodine and a specific tested solution. A yellow or brown solution suggests a negative solution. A dark blue/purple or black result is a positive solution. It advised to be vigilant with testable solutions that are originally dark in color for the results are more difficult to determine after conducting the

In recent years, experts in the health and wellness community have debunked the old line of thinking that fats are hazardous to health. With this news, one type of fat has been recognized as being most essential to human health: omega-3 fatty acids. These good-for-you fats provide an abundance of health benefits, but the body cannot make them.

The purpose of this lab is testify the % fat in meat, which is Beef Franks. We use the whiley extractor unit to separate fat from protein by dissolve the fat in acetone. % fat in meat= weight of extracted fat/weigh of fresh meat *100 is used to calculate for % fat in meat in this experiment. It is a simple experiment that involved intense degree heat, cool water, meat in an extraction thimble inserted into a flask, and acetone. The percentage error is 50.6%.

Fish oil is a typical term used to refer to two sorts of omega-3 unsaturated fats: eicosapentaenoic corrosive (EPA) and docosahexaenoic corrosive (DHA). These omega-3 fats are normally found in fish, creature items and phytoplankton. Fish oil is suggested as a wellspring of these omega-3 fats as they are the least expensive and most normal wellspring of them. Fish oil gives an assortment of advantages when supplemented, especially

We also get iodine from the food we eat. Iodine can become dangerous when we don't eat enough of it and too much. Iodine deficiency will slow down the thyroid function and cause it to swell up. Too much iodine can affect the whole body. Loss of weight and disturbed heartbeats can occur.Iodine minerals are very rare. Salt solutions often contain a little iodine and 0.3% of iodine can be contained in sodium and calcium nitrate deposits. It can also be extracted from seaweed.It can melt at 113.5°C and boil at 184°C. It dissolves only slightly in water, but other liquids can give it a higher solubility.One of the first commercial uses for Iodine was for Photography. It was used in a technique for producing images on a piece of metal. These images were called daguerreotypes. As well as photographic chemicals, iodine now has many more uses. Iodine salts are used in pharmaceuticals and disinfectants, printing inks and dyes and animal feed supplements. It is also used to make polarising filters for LCD displays.Iodine is also added in small amounts to table salt, to avoid iodine deficiency. The radioactive isotope (iodine 131) is sometimes used to treat cancerous thyroid

A molecule of dietary fat typically consists of several fatty acids (containing long chains of carbon and hydrogen atoms), bonded to a glycerol. They are typically found as triglycerides (three fatty acids attached to one glycerol backbone). Fats may be classified as saturated or unsaturateddepending on the detailed structure of the fatty acids involved. Saturated fats have all of the carbon atoms in their fatty acid chains bonded to hydrogen atoms, whereas unsaturated fats have some of these carbon atoms double-bonded, so their molecules have relatively fewer hydrogen atoms than a saturated fatty acid of the same length. Unsaturated fats may be further classified as monounsaturated (one double-bond) or polyunsaturated (many double-bonds). Furthermore, depending on the location of the double-bond in the fatty acid chain, unsaturated fatty acids are classified as omega-3 or omega-6 fatty acids. Trans fats are a type of unsaturated fat with trans-isomer bonds; these are rare in nature and in foods from natural sources; they are typically created

Flaxseed oil comes from the seeds of the flax plant. The oil contains both omega-3 and omega-6 fatty acids. Flaxseed oil contains the fatty acid ALA (alpha-linolenic acid) which is then converted by the body to DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid). It is estimated that the body will only convert about 5% of ALA into DHA and EPA. Because of this, fish oil is a better alternative for DHA and EPA but flaxseed oil does have its uses.

Iodine consumption immediately increases the detoxification of bromide, fluoride, and some heavy metals including mercury, lead, cadmium, and aluminum. Bromide and fluoride are only removed by iodine, and no other chelator or detoxifying technique. Many people know that toxic halides, such as fluoride and bromide, have an effect on the receptors in the body similar to iodine, and can inhibit iodine absorption and binding in the body. Even though iodine is part of the halides family, which are all opposing elements to iodine, they will obstruct the absorption of iodine. We are all exposed to bromine and fluorine, your bodies are storing these toxic chemicals in the receptors meant for iodine. The human body’s receptors are primitive and lacking
