Fat chance: Cholesterol leads boffins to discover world's oldest animal fossil – 558m years old

Kudos for the pun ; there is no "good" or "bad" cholesterol though. Cholesterom serves as a lipid transporter in the blood, and the transport structures ("lipid droplets", to simplify) have different densities depending on the direction of the transport (to or from reserves).

An imbalance in the abundance of these different structures reflects an imbalance in the lipid metabolism (it cut both ways : too little "bad cholesterol" also reflects an issue, altough -outside of metabolic diseases- it's much less common in our overfed societies).
