Ethanol is used in the free fatty acid test to dissolve the free fatty acids present in the sample, enabling them to be separated and quantified accurately. Ethanol helps to extract the free fatty acids from the sample into solution for analysis, thus allowing for the determination of the free fatty acid content in the sample.

Yes, ethanol can affect a breath test by causing a higher reading due to its presence in the breath. Breath tests are designed to measure the amount of alcohol in the breath, which correlates to blood alcohol concentration. Ethanol in the breath can lead to a false positive result on a breath test.
When ethanol is added to alkaline KMno4 solution, the ethanol gets oxidised to ethanoic acid due to nascent oxygen. KMno4 is an oxidising agent. thus when we first add alkaline Kmno4 to ethanol, the pink colour of the Kmno4 vanishes, as it is being used up for the oxidation process. however. when all of the ethanol has been oxidised into ethanoic acid, and we keep adding Kmno4, the colour returns, as there is no more ethanol left to oxidise.
No, you should not use ethanol instead of water when conducting the iodoform test. The test relies on the reaction of iodine with an alcohol in the presence of a base, typically sodium hydroxide, to form iodoform. Water is usually used in the test to help facilitate the reaction. Substituting ethanol for water can affect the outcome of the test.
Gas chromatography and mass spectrometry are the confirmatory tests used to detect ethanol in biological samples. These tests are highly specific and sensitive, allowing for accurate quantification of ethanol levels in a sample. Additionally, enzymatic assays can also be used for confirmation of ethanol presence.
The saponification test is used to determine the amount of free fatty acids present in oil. During saponification, free fatty acids react with a strong base to form soap. By measuring the amount of base required for saponification, the free fatty acid content of the oil can be calculated, which is important for assessing oil quality for various applications.
The FFA (free fatty acid) test is a way to measure of the rancidity of an oil. In edible oils, it is a valuable test to detect potential off flavors due to age, improper storage or handling. Peroxide value is also a similar test.
An acid value test is preformed on butter to gauge the levels of free fatty acids. Butter when fresh is in the state of being a triacylglycerol, 3 fatty acid chains attached to a glycerol backbone. When a butter ages it undergoes a process of oxidation called lipolysis. This is where the fatty acid chains split from the glycerol backbone the result of which is the formation noticeably off flavours being present in the butter. Hence the point of using old and new butter is that the old butter should have a higher acid value than the fresh butter.

It affects triglycerides by increasing lipolysis and therefore free fatty acid/glycerol levels, don't think it affects LDL cholesterol.
It ought to since ethanol is the alcohol that is in beverages.

In most cases, yes.
Acid test or litmus test means to try it an see. The acid test of a cake is eating it. The acid test of a new idea is seeing if it works.
