Dehydration synthesis (here we go again!! Same vocabulary over
and over!!)• Lipids also contain C, H, O
elements from CHNOPS
• contain units of 1 molecule glycerol linked to 3 fatty acids (called a triglyceride) through dehydration synthesis (makes water)
Lipids
• A Lipid is called a triglyceride and it’s formed by dehydration synthesis (remove water) and it is broken down by hydrolysis (adding water)
Types of Lipids
• saturated fats-animal fats that are solids at room temperature (contain single bonds)-solids-ex. Butter (hint: to remember saturated is single bonds think of the “s” in saturated and the “s” in single)
Types of Lipids
• unsaturated fats- oils from plants (contain double bonds)-liquids at room temperature
• ex. Olive oil
Unsaturated fats contains double bonds while saturated fats contain single bonds in the fatty acid chain
Types of Lipids
• cholesterol-lipid found in animal foods
• helps build cell membranes• Note: not all cholesterol is bad, you
do need some to build your cells but you don’t want a lot because it can lead to blocked arteries, etc.
