Chirality change for lipids in LMSD

5th June 2024

A recent paper in Angewandte Chemie by the Minnaard group highlighted that the long-established chirality of Mycolipanolic acid was incorrect. Stereoselective chemical synthesis of this mycobacterial cell-wall constituent proved the chirality of the alpha-methyl and beta-hydroxy groups needed to be inverted.

Accordingly, we have revised the structure in LMSD and that of all those molecules containing mycolipanolic acid, around 750 lipids in total. 

Check these lipids out on LMSD

Shorthand nomenclature updates

6th May 2024

Recent research strongly suggests that there may be many more bile acid amidates (bile acids conjugated with amino acids) in nature than previously thought. We have updated the shorthand nomenclature to include these as a suffix of; Xxx, where Xxx is the three letter amino acid code. For instance Phenylalanocholic Acid (LMST05050056) is now ST 24:1;O4;Phe.

For consistency, glycine conjugate shorthand now ends; Gly rather than ;G. Similarly, taurine conjugates change from ;T to ;Tau to remove any potential ambiguity. 

We have also updated the shorthand for bile acid conjugates, which previously included the leaving oxygen that is displaced to form the amide bond. This has been removed such that only the oxygens present in the bile acid residue are enumerated. For example the shorthand for glycocholic acid (LMST05030001) changes from ST 24:1;O5;G to ST 24:1;O4;Gly.

Lipid nomenclature update

2nd October 2023

A word on the use of the "C" prefix in lipid shorthand nomenclature (e.g "C16:0"). Some institutions and companies use it to describe acyl carnitines whereas others use it for fatty acids. This ambiguous nomenclature should be avoided by choosing "CAR" (e.g "CAR 16:0") for acyl carnitines and "FA" (e.g "FA 16:0") for fatty acids. More details on recommendations by the Lipidomics Standards Initiative and International Lipid Classification and Nomenclature Committee are found in the LIPID MAPS nomenclature section.

New lipid classes added to COMP_DB

15th March 2022

COMP_DB, the LIPID MAPS computationally-generated database of "bulk" lipid species has just been extended to include new classes of betaine lipids which occur in organisms such as algae, bryophytes and fungi.

Whilst LMSD contains fully characterised lipids, COMP_DB species indicate only the number of carbons and double bond equivalents, but not chain positions or double bond regiochemistry and geometry.

In many lipidomics studies, this is the level of characterisation achieved, so expanding COMP_DB to include DGCC, DGTA and DGTS lipid classes will help those working on these to identify potential lipids in their data.

NEW: Reactions explorer

9th February 2022

We are developing a reactions explorer to visualise and obtain information on biochemical reactions and metabolic pathways involving lipids.

In the explorer, you can navigate through the complex network of lipid reactions and use the filtering tools to quickly find relevant reactions for your lipid class of interest.

Our lipid reactions database is linked to the LMSD database so you can now find on specific lipid pages reactions in which they might take part.

New classes of betaine lipids

29th November 2021

Research over the last few years has shown the abundance of diacylglycerols with betaine headgroups in organisms such as seaweeds, algae and fungi. Recognising this, we’ve updated LMSD and added classes of betaine mono- and di-radylglycerols in the glycerolipids category. Existing betaine lipids have been moved into these classes. 

Due to the experimental difficulty, the position of acyl chains, and double bonds within them, has yet to be determined for many betaine lipids, so there are doubtless many more to add to LMSD in coming years.

12th March 2021

We are looking for experts in lipid biochemistry to help create a new knowledge base.
During the next 6 months LIPID MAPS will be working with WikiPathways to support expert community curation of lipids and pathways/networks for lipidomics. We plan to create new pathways and then integrate these with LIPID MAPS Structure Database (LMSD) to enable development of tools for lipidomics systems biology.

To do this, we need our curation team to work with domain experts in specific lipid pathways so we can capture high quality accurate biochemical information, including reactions, genes, organism/tissue localisation of lipids and their reactions.
Are you working on a lipid metabolic pathway, and are interested to be involved?
Curated information will be tagged with publications and contributors will be credited.
Please get in touch with Valerie O’Donnell: [email protected]
