Biology (Day 3; Lipids and Nucleic Acids) Flashcards
Lipids and Nucleic Acids
What is unique about lipids?
they are not so water soluble
What impacts do lipids have on biology?
energy storage, signaling, and membranes
Why are lipids not so water-soluble?
Water is a polar molecule, whereas lipids are non-polar molecules. Therefore, there is no way for water to attach to a lipid molecule.
Fats are ___, but not all ___ are fats.
lipids
Property of molecules that do not mix with water
Hydrophobic
Property of molecules that do mix with water
Hydrophilic
What is the relationship between nucleic acids and nucleotides?
Nucleic acids are the polymers of nucleotides (monomers)
What impacts do nucleic acids have on biology?
storing information (DNA)
Why are nucleic acids acids even though they have a basic component?
The basic parts form the rung, so they are less reactive compared to the outside acidic parts.
Why is it that not all lipids are fats?
Lipids include other types of molecules beyond those just classified as fats. Fats are one type of lipid.
