Isotope Labeled Lipids

Name: Isotope Labeled Lipids
Brand: BOC Sciences

Stable isotope-labeled lipids are lipid derivatives prepared by replacing specific atoms in natural lipid molecules with stable isotopes such as ^13C, ^2H, ^15N, or ^18O. Compared with natural lipids, isotope-labeled lipids are highly similar in structure but generate unique signals in analytical techniques like mass spectrometry (MS) and nuclear magnetic resonance (NMR). This enables researchers to accurately trace lipid metabolism, distribution, and interactions within complex biological systems. As a professional provider of custom lipid compounds, BOC Sciences offers comprehensive stable isotope-labeled lipid services, covering everything from custom synthesis, structural analysis, and modification to conjugation, supporting research institutions, drug development teams, and industries such as functional foods and cosmetics in advancing their projects efficiently.

Case Studies and Success Stories

Background

Lipid metabolism disorders are closely associated with various diseases such as diabetes, atherosclerosis, and non-alcoholic fatty liver disease. To gain deeper insights into lipid metabolic pathways and their dynamic changes in vivo, researchers need to track lipid synthesis and degradation at both cellular and animal levels. However, traditional unlabeled lipids cannot distinguish between endogenous and exogenous sources, which limits metabolic flux studies. A U.S.-based research team urgently required high-purity, fully ¹³C-labeled phospholipids for metabolomics tracing experiments during their study on hepatic lipid synthesis and utilization mechanisms.

What Does BOC Sciences Do?

BOC Sciences' isotope chemistry experts designed and synthesized uniformly ¹³C-labeled phospholipids according to the client's requirements and ensured their suitability for metabolic studies:

Provided ¹³C-labeled glycerol backbone and fatty acid chains to enable clear signal differentiation in LC-MS/MS analysis;
Verified labeling positions and efficiency (>98%) using high-resolution mass spectrometry (HRMS) and NMR;
Delivered products in scales from several hundred milligrams to gram quantities, meeting the needs of both cell culture and animal experiments.

Key Outcomes

The research team successfully traced phospholipid synthesis and degradation pathways in hepatocytes using the labeled phospholipids;
Data revealed key enzymatic regulation nodes within the metabolic network, providing new evidence for disease mechanism studies;
The results supported the publication of high-quality metabolomics research papers and provided an important foundation for subsequent drug target development.

Background

Cholesterol and its derivatives play vital roles in membrane stability, hormone synthesis, and lipid transport. During drug development, it is essential to perform quantitative studies on cholesterol-related lipid metabolism to clarify a drug's potential impact on lipid homeostasis. A European pharmaceutical team required high-purity ²H (deuterium)-labeled cholesterol derivatives as internal standards for LC-MS quantitative analysis while evaluating the distribution and metabolism of a novel lipid-lowering drug in vivo.

What Does BOC Sciences Do?

BOC Sciences customized the synthesis of ²H-labeled cholesterol derivatives tailored to the client's needs and ensured their suitability for pharmacokinetic quantitative research:

Applied selective deuteration techniques to introduce ²H atoms at stable positions of the cholesterol backbone, ensuring clear signals without altering biological properties;
Provided comprehensive quality control data, including deuterium incorporation rate, positional verification, and isotopic distribution analysis;
Delivered small-scale products (tens of milligrams to gram quantities) that met bioanalytical study requirements.

Key Outcomes

The client team used the ²H-labeled cholesterol as an internal standard, achieving highly sensitive LC-MS/MS quantification;
Pharmacokinetic results indicated that the new drug had limited impact on cholesterol homeostasis, increasing confidence in safety assessment;
High-quality stable isotope-labeled standards enabled the client to successfully complete preclinical studies and accelerate drug development progress.
