FAQ
What is LMLipidCalc1 used for?
LMLipidCalc1 is used to support lipid biochemists in their lipidomic investigations. It calculates the accurate mono-isotopic molecular weight of tens of thousands of lipid molecular species, as well as positive and negative molecular ions and common ion adducts.
What lipid classes can LMLipidCalc1 calculate?
LMLipidCalc1 supports fourteen different lipid classes and subclasses for precise m/z calculation. This includes phospholipids, sphingolipids, cholesteryl esters, acyl CoA esters, wax esters, acyl carnitines, cardiolipins, and glycerides.
Does LMLipidCalc1 support custom lipid structures?
Yes, for lipids containing fatty acyl groups, you can select up to 30 different acyl groups from a dropdown menu to build the lipid class structure. This allows for precise calculation of complex lipid species.
What types of ions can LMLipidCalc1 calculate?
LMLipidCalc1 can calculate ions as [M+H]+, [M-H]-, or common ion adducts with alkali metals or organic acid anion adducts. It provides a table of common positive and negative molecular ion species.
Does LMLipidCalc1 include other important biomolecules?
Yes, in addition to lipids, LMLipidCalc1 also includes fatty acids, fatty acid lipid mediators like prostaglandins and leukotrienes, steroids, sterols, bile acids, dolichols, prenols, and lipid-soluble vitamins like A, D3, E, and K, as well as coenzyme Q.
How accurate are the m/z calculations in LMLipidCalc1?
The m/z is calculated at millimass unit accuracy. This high level of precision is crucial for accurate identification and analysis in lipidomic studies.
What devices is LMLipidCalc1 available on?
LMLipidCalc1 is available for iPhone, iPad, and iPod devices. It is designed to be accessible on common Apple mobile platforms.
When was LMLipidCalc1 last updated?
LMLipidCalc1 was last updated on December 21, 2020, with version 2.2.2. The application was also released on this date.
