Lipids
Fichas del conjunto (15)
- 1Are lipids considered to be hydrophobic or hydrophilic?Majority hydrophobic
- 2Why don't lipids dissolve in water?Lipids don't dissolve in water because lipids are non-polar molecules therefore they have no charge. Since lipids have no charge, and water is a solvent that needs the solute to be charged in order for it to dissolve
- 3What happens to lipids in water since they don't dissolve?Lipids aggregate meaning they cluster together tightly by themselves
- 4What holds together lipids in an aggregate?NO bonds hold lipids together in an aggregate, only a thing called a hydrophobic interaction
- 5Why do lipids form an aggregate?Lipids form an aggregate because
they are hydrophobic and this is a way of "protecting" themselves against the water - 6What are monmers of lipids?Fatty acids
- 7What are fatty acids composed of?They are composed of a carboxyl group and a hydrocarbon tail
- 8Why are fatty acids amphipathic?Fatty acids are considered to be amphipathic because they are both hydrophobic and hydrophilic
- 9What are the 3 different types of fatty acids?1. Saturated
2. Unsaturated
3. Trans fat - 10How can a saturated fatty acid be described?1. Linear structure
2. No kinks in hydrocarbon tail
3. No double bond
4. Saturated with hydrogen - 11How can a unsaturated fatty acid be described?1. Kink in hydrocarbon tail
2. Double bond present
3. Plant-based fatty acid - 12How can a trans fatty acid be described?1. Mostly man made
2. Took a unsaturated fat and made it saturated - 13What state would animal fat be in at room temperature?Animal fat at room temperature will be a solid
- 14What state would a plant based fat be at room temperature?A plant based fat at room temperature would be a liquid
- 15What state would a trans fat be at room temperature?A trans fat at room temperature would be a solid
