understanding saturated lipids and unsaturated lipids

Post by pefrac » Tue Dec 06, 2005 4:39 am

saturated lipids are the ones with no double bonds and are solid at room temperature and are called Low density lipids.
unsaturated fats are the ones with double bonds and are liquid at room temperature and are called High density lipids.
or so i'm told....
now if saturated lipids have more hydrogens than unsaturated lipids, then...... why are saturated lipids called Low density, when in fact, they seem more dense than unsaturated lipids? someone explain this to me...

also the fatty acids on lipids can be either bent or straight, the straight ones are saturated and the bent or curved ones are unsaturated.
this is due to a different place of the hydrogen bon, rather than a 1,4 bond its a 1,6 bond which causes it to curve.
