Actually, these examples are more a consequence of what one might call dietary lipid abuse rather than implying that lipids are inherently damaging or dangerous. Lipid Hydrophobic , organic biomolecules.
Lipids play energy storage and structural roles in cells, and many hormones are lipids.
Fatty acids are organic acids, particularly ones consisting of not branched chains of carbon. Instead, fatty acids are found primarily as components of triglycerides , or as phospholipids . Indeed, free fatty acids are sufficiently unusual in and about life that they may be effectively employed as antibacterial agents. In addition, the placement of double bonds in carbon chains may vary. The presence of double bonds implies that the carbon chain of a fatty acid is not saturated with hydrogen atoms.
