2 Common Forms
What is steroids, phospholipids, and triglycerides
Definition of polarity
Hydrophilic and dissolves in water
2 Common Functions
What is storing energy/protection, forming cell membranes, communication between hormones, and supplying cells with energy.
6 atoms most often found in lipids.
What is Carbon, Hydrogen, Oxygen, Sulfur, Nitrogen and Phosphorous
Place with high concentration of triglycerides
What is blood
Hydrophobic and hydrophilic Lipid.
What is phospholipid?
When is storing energy in the form of lipids bad, and why?
When you consume too many because it can lead to weight gain.
The most common formula for lipids
What is CH3(CH2)nCOOH where n is an even number between 2 and 28
The second messengers in signalling pathways, they have somewhat differing molecular structures, but are classified as lipids because of hydrophobic properties
What is steroids?
Definition of Amphipathic
What is something that has both hydrophilic and hydrophobic parts?
Lipids relationship with homeostasis.
(example)
What is lipids maintain temperature in body, allowing them to also protect organisms from the environment.
(ex. Including hydrophobic properties forming protective layer over fur or feathers to keep animals dry.)
