Multi-spectrometric analyses of lipoteichoic acids isolated from Lactobacillus plantarum

► In our previous studies, pLTA from Lactobacillus plantarum showed anti-inflammatory effects. ► We examine the structure of pLTA compared with aLTA from Staphylococcus aureus. ► pLTA possesses α-linked glucose and galactose substituents instead of GlcNAc on aLTA. ► The unsaturated fatty acids and third acyl chains are the distinctive features. ► The third acyl chains on glycolipids are identified by its diagnostic ions.
