Answer:

TRUE OR FALSE

1.TRUE-Most lipids are non-polar (having no charged areas) or only slightly polar, with a very few charged areas.

2.TRUE-Triacylglycerols, lipid membrane and cholesterol can be synthesized by the organisms through various pathways.

3.FALSE-Lipids are poor conductors of heat, making them fantastic insulators.

4.TRUE-Oxidative rancidity: When a part of unsaturated fatty acid oxidized to form aldehyde ketone, the phenomenon is termed as oxidative rancidity.

5.TRUE-Soap is produced by the saponification (hydrolysis) of a triglyceride (fat or oil).

6.TRUE-Lipids perform three primary biological functions within the body: they serve as structural components of cell membranes,

7.TRUE-An unsaturated fat can be made in to a saturated fat via hydrogenation reactions.

8.TRUE-Lipids are commonly defined as a broad category of non-polar molecules that are sparingly soluble or insoluble in water, but soluble in benzene, chloroform, hexane, methanol and diethyl ether.

9.TRUE-These are surface-active agents.

10.TRUE-(2)Soap is produced by the saponification (hydrolysis) of a triglyceride (fat or oil).

11.TRUE-Lipids are composed mainly of carbon and hydrogen, but they can also contain oxygen, nitrogen, sulfur, and phosphorous.

12.TRUE-Emulsification is the process of dispersing two or more immiscible liquids together to form a semistable mixture. In food applications, these two liquids generally consist of an organic (oil) phase and an aqueous (water) phase that is stabilized by the addition of a food-grade emulsifier (surfactant).

13.TRUE-The functions of lipids include storing energy, signaling, and acting as structural components of cell membranes. Lipids have applications in the cosmetic and food industries as well as in nanotechnology.

14.FALSE-The alkaline hydrolysis of oils and fats is called Saponification.

15.TRUE-Lipids are non-polar molecules, so they are not soluble in polar solvents like water.
