Lipid Profile Comparison and Analysis

The analysis approach was recently described^{28 (link)}. In brief, significance of differences between mean contents of DAGE and alkylglycerols was tested by one-way analysis of variance (ANOVA). Raw data were used following evaluation of the homogeneity of variances (Levene’s test) and the normality of data distribution (Shapiro–Wilk test). For the cluster analysis, the unweighted pair-group method with arithmetic mean and the Euclidean distance as dissimilarity metric were applied to the percentage content of molecular species of DAGE and four GPL classes according to the structure of their non-polar parts. All statistical analyses were performed using STATISTICA 5.1 (StatSoft, Inc., USA). A statistical probability of p < 0.01 was considered significant. Values are represented as mean ± standard deviation.
