Characterization of lipid structure associated with intensive lactation at baseline. A Association between lactation intensity groups and lipid structure including the number of carbon atoms and double bonds in each lipid species from 15 lipid classes. Log2 FC of each lipid species are indicated with dots, with color of dots indicating log2 FC value, and dot size denoting significance by FDR value. B Association between lactation intensity and fatty acid composition in 15 lipid classes. Red and blue color indicate log2 FC with significance (FDR < 0.05), whereas white color denotes no significant difference, and grey color indicates not detected
