Cholesterol is the primary membrane sterol in animal cells, where it plays a crucial role in maintaining membrane fluidity and integrity. Additionally, some fungi, such as certain species of yeast, utilize cholesterol in their membranes, although they primarily use ergosterol. In contrast, plants and most other organisms generally employ different sterols, such as sitosterol or stigmasterol, instead of cholesterol.

Cholesterol is a common sterol found in cell membranes and is essential for various bodily functions, such as hormone production and digestion.
The primary components of egg yolks and peanut oil are lipids. Lipids are different kinds of substances like sterol and triglycerides. A large egg yolk contains about 210 milligrams of cholesterol, and 100 grams of peanut oil contains about 17 grams of saturated fats. While cholesterol is a type of sterol, saturated fats are triglycerides.

A zoosterol is a sterol found in animal tissue.
To detect sterol glucoside using a dual beam UV-Vis spectrometer, first prepare a sample solution of the sterol glucoside in a suitable solvent. Measure the absorbance spectrum of the sample in the UV-Vis range (typically 200-400 nm) to identify characteristic absorption peaks associated with sterol glucosides. Compare the obtained spectrum with standard reference spectra to confirm the presence of sterol glucoside. Ensure to use a blank solvent to calibrate the spectrometer for accurate results.
