Question

Indicate which of the following statements are true regarding fats.

Question options: (all that apply)

	In a fat the three carboxylic acid moieties have to be identical.
	A fat containing unsaturated fatty acids will have a lower melting point, and will usually be an oil.
	A triglyceride can be either solid or liquid.
	A fat is a triglyceride, which is a triester of glycerol with three carboxylic acids.

Answer 1

Dear friend your answers are true regarding fats

A fat containing unsaturated fatty acids will have a lower melting point, and will usually be an oil.

A fat is a triglyceride, which is a triester of glycerol with three carboxylic acids.

A triglyceride can be either solid or liquid.

About Triglycerides:

                    Naturally occurring triglycerides may be either solid or liquid at room temperature. Commonly, solid triglycerides are called fats and liquid triglycerides are called oils. The carboxylic acid moieties involved in forming fats and oils are often referred to as fatty acids (even numbered, C12-C18 mostly).

Triglycerides which have all or most of their acidic moieties saturated are most often solid.

Triglycerides which have most of their acidic moieties unsaturated are more often liquids

Triglycerides are naturally occurring tri-esters of 1,2,3-propanetriol (glycerol; also called glycerin)

A fat containing unsaturated triglycerides have lower m.p.’s (i.e., are liquid at room temperature) due to cis double bonds and trans double bonds tend to have higher m.p.’s than the ones with cis double bonds, and thus to be solid at room temperature

Thank you.
