What are Sterol Lipids?
Sterol lipids are a class of naturally occurring molecules that play essential roles in cellular and metabolic functions. Structurally, sterols are polycyclic hydrocarbons with a hydroxyl group attached to one of the carbon rings, which gives them amphipathic properties (both hydrophobic and hydrophilic). This unique structure allows sterols to integrate into biological membranes, where they contribute to membrane fluidity and stability.
Sterols are also precursors for a variety of bioactive molecules, including steroid hormones, bile acids, and vitamins D and K. These hormones regulate critical physiological processes such as metabolism, immune function, and reproduction. In humans, cholesterol is the most well-known sterol, serving not only as a building block for hormones like estrogen, testosterone, and cortisol, but also in the synthesis of bile acids needed for digestion.
Sterols can be categorized into three primary subclasses based on their structural differences:
- 4,4-desmethylsterols: These sterols lack a methyl group at position 4.
- 4a-methylsterols: These contain a methyl group at position 4a.
- 4,4-dimethylsterols: These sterols have two methyl groups at position 4.
Due to their complex and diverse chemical structure, sterols are found across various organisms, including animals, plants, and fungi, each contributing uniquely to the organism's metabolism. For example, in plants, phytosterols such as β-sitosterol play key roles in membrane structure and plant growth, while in animals, cholesterol is integral to cellular functions and the production of vital hormones.
What Specific Projects Does Creative Proteomics Offer?
At Creative Proteomics, we offer a specialized Sterol Lipids Analysis Service designed to support cutting-edge research in lipidomics, metabolic studies, and drug development. Our service is tailored for researchers and laboratories seeking precise and reliable quantification of sterol lipids in various biological samples.
Quantification of Sterol Lipids:
We provide high-throughput, accurate quantification of over 30 different sterol lipids from a variety of sources, including animal tissues, plant extracts, and microbial cultures. Our analysis covers common sterols such as cholesterol, phytosterols (e.g., β-sitosterol), and mycosterols.
Sterol Profiling:
Researchers can obtain a comprehensive sterol lipid profile from their samples, enabling a deeper understanding of sterol composition across different biological systems. This profiling can be used to study metabolic pathways, evaluate dietary influences on lipid metabolism, or monitor changes in sterol levels under various experimental conditions.
High-Resolution Detection:
Using advanced Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS) technology, we achieve high-resolution separation and precise quantification of sterols, even at trace levels. This approach ensures that subtle variations in sterol concentrations are accurately captured, which is essential for studies focused on lipid metabolism and disease modeling.

Methods for Sterol Detection
Liquid chromatography tandem mass spectrometry (LC-MS/MS) technology is one of the commonly used metabolites detection and analysis methods. Due to its strong specificity, high sensitivity, and fast analysis speed, it is favored by mass spectrometry scholars and medical researchers.
In order to provide better service, Creative Proteomics has developed a high-throughput, high-coverage, high-sensitivity targeted quantification method for steroids. Through one analysis, the levels of multiple steroid hormones can be quantified at the same time, which can effectively save manpower and material resources, improve throughput and meet the detection requirements of most steroid hormones in the laboratory.
