Correlation circle of the principal component analysis summarizing fatty acid composition in blood. The fatty acid composition (in percentage) was obtained in the plasma prepared from the whole blood of 47 growing pigs by using gas chromatography. Some of the individual FA were grouped in biologically relevant families (saturated FA with 14 carbons or less, omega-6 sum of $n-6$ and omega-3 sum of $n-3$), whereas the other fatty acids were kept as these
