Lipids Include fats and steroids:
- Oil cannot mix with water due to lipids
- Water avoiding molecules are hydrophobic
- Lipids act as boundaries for water to your cells
- a fat is a 3-carbon backbone called glycerol attached to 3 fatty acids that have long hydrocarbon chains
- Fat stores energy for later use
- A saturated fat is a fat that contains the most hydrogen atoms possible
- an unsaturated fat is a fat with at least 1 less possible than the max hydrogen atom
- A lipid molecule that the carbon skeleton forms 4 rings is a steroid
- Steroids all have 4 rings but the positioning affect the type of steroid it is
- Steroids are hydrophobic
- Cholesterol is a steroid that is found in the membranes of your cells
- only a certain type of cholesterol is bad
1. What properties do lipids share?
Lipids are all hydrophobic
2. What are the parts of a fat molecule?
A 3 carbon backbone and 3 fatty acids with long hydro carbon chains
3. Describe 2 ways that steroids differ from fats.
Steroids circulate the body as chemical signatures, and structure is different
4. What does the term unsaturated fat on a food label mean?
Unsaturated means that it doesn't have the most possible water molecules it could have
