Fig. 4

Illustrative scheme of changes in the cellular membrane lipid composition of tilapia reared at high density (HD) and low density (LD). Under high density, there is a higher proportion of Phosphatidylcholine (PC), resulting in a more rigid membrane. Under low density, increased production of Lysophosphatidylcholines (LPC) and Lysophosphatidylethanolamines (LPE) is observed, promoting greater membrane fluidity. The conversion of PE to PC occurs via methylation, while phospholipid degradation is mediated by phospholipases A1/A2 (PLA1/A2), and re-conversion by acyltransferases (AT).
