Isoflavones and phenols are both present in soybeans.
Phenols are the basic building block of many plant constituents; many different phenolic compounds exist that are based on it. One such compound is salicylic acid, which is often combined with a sugar to form glycoside that is antiseptic. Saponins are glycosides. The steroidal saponins mimic the precursers of female sex hormones, and the tri-terpenoid saponins mimic the adrenal hormone ACTH. Saponins are present in small amounts in soybeans. Isoflavones are very similar in structure to estrogen.
Phenols have a low acidity.
Soy lecithin typically does not contain significant amounts of isoflavones. Lecithin is primarily a fat extracted from soybeans, and the process of extracting lecithin usually removes most of the isoflavones, which are a type of phytoestrogen found in whole soy products. Therefore, while soy lecithin is derived from soy, it is not a notable source of isoflavones.
Phenols give a positive test.

Only if it's smoked - pork is naturally free from phenols, but the smoking process adds them.
Phenols can be tested using several methods, one common approach being the use of Ferric Chloride (FeCl3) solution. When a phenolic compound is added to this solution, a color change occurs, typically resulting in a purple or violet color, indicating the presence of phenols. Another method involves the use of bromine water, where phenols will decolorize the solution due to the formation of brominated derivatives. Additionally, the pH test can help differentiate phenols from other alcohols, as phenols typically exhibit acidic properties.
A positive test for phenols using ferric chloride is recognized by the formation of a colored complex. When phenols react with ferric chloride, a deep purple or blue color indicates the presence of phenols. This color change occurs due to the formation of an iron-phenol complex.
No, turmeric does not contain soy isoflavones. Turmeric is a spice derived from the root of the Curcuma longa plant and is primarily known for its active compound, curcumin. Soy isoflavones, on the other hand, are phytoestrogens found in soybeans and other soy products. Although both turmeric and soy have health benefits, they come from different sources and contain different compounds.
Soy contains phytoestrogens, specifically isoflavones like genistein and daidzein, which can mimic estrogen in the body. The amount of these isoflavones in soy products varies widely, but on average, whole soybeans contain about 100 to 200 mg of isoflavones per 100 grams. The actual estrogenic effect can vary based on individual metabolism and the specific soy product consumed.
Types of phenols found in industrial wastewater include cresols, pentachlorophenol, bisphenol A, and chlorophenols. These compounds can be toxic to aquatic life and can cause environmental damage if released untreated into water bodies.
