LIPIDS
The Lipid Knowledge Challenge
Test your understanding of lipids, vital organic compounds that play crucial roles in biological systems!
In this quiz, you will cover various categories of lipids, their structures, fun
- Fatty acids
- Complex lipids
- Hormones and their structures
- Biological significance of lipids
THESE organic compounds are nonpolar molecules, which are soluble only in nonpolar solvents and insoluble in water because water is a polar molecule.
A __________ lipid cannot be disintegrated into smaller molecules through hydrolysis. __________ lipids include cholesterol, prostaglandins, etc
A __________ lipid comprises one or more ester groups, enabling it to undergo hydrolysis in the presence of a base, acid, or enzymes, including waxes, triglycerides, sphingolipids and phospholipids.
__________ lipids are esters of fatty acids containing groups in addition to alcohol and fatty acid. Examples are phospholipids, glycolipids, and other complex lipids.
Lack of carbon-carbon double bonds indicate that the fatty acid is __________. The __________ fatty acids have higher melting points compared to unsaturated acids of the corresponding size due to their ability to pack their molecules together thus leading to a straight rod-like shape.
__________ ARE “esters” found in:
- fruits and leaves of many plants that can safeguard them from small predators and dehydration.
- fur of a few animals and the feathers of birds possess the same coatings serving as water repellants.
and
- carnauba wax for its water resistance and toughness (significant for car wax).
