WebStearin / ˈ s t ɪər ɪ n /, or tristearin, or glyceryl tristearate is an odourless, white powder. It is a triglyceride derived from three units of stearic acid.Most triglycerides are derived from at least two and more commonly three different fatty acids. Like other triglycerides, stearin can crystallise in three polymorphs.For stearin, these melt at 54 (α-form), 65, and 72.5 °C (β … WebFor the given compound we would expect to see the following peaks in the IR spectrum, peak at 3200-2600 cm-1 for -OH of carboxylic acid peak a … View the full answer Transcribed image text: Predicting which peaks you expect to see in …
