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 with various alcohols. Examples are fats and waxes

__________ 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.

__________ fatty acid is indicated when a fatty acid has more than one double bond.

__________ 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).

__________ ARE a kind of hormone that is typically recognized by their tetracyclic skeleton, composed of three fused six-membered and one five-membered ring, as seen above.

__________ is a wax-like substance, found only in animal source foods. Triglycerides, LDL, HDL, VLDL are different types of ___________ found in the blood cells.
