From: The effect of hypoxia on the lipidome of recombinant Pichia pastoris
Principal component analysis (PCA) of lipidomic data. Principal component analysis of the lipidome data in a biplot of components one and two. The biplot shows lipidomic data (scores) as labelled dots and treatment effect (loadings) as vectors. Vectors that are close together are highly correlated in terms of the observed lipidomic content, while vectors that are orthogonal are poorly correlated. PC1 correlates well with the change due to fluconazole treatment, whereas PC2 appears to be correlated with the change in oxygen conditions
