Which of the following are true of trans-fatty acids?

Select all that apply.

1 often created by treating plant oils with hydrogen
2 cause the shape of fatty acids to be incorrect
3 help membranes function normally
4 occur naturally in in food

The following given statements are true of trans-fatty acids:

A. Often created by treating plant oils with hydrogen

D. Occur naturally in in food

Explanation:

The unsaturated fatty acids that are produced by a method called hydrogenation through the addition of a hydrogen molecule to vegetable oils is understood as "Trans-fatty acids". According to the hydrogenation process the composition of the fatty acids varies. The unsaturated fatty acids trans structure receives one double conjugated bond and obtains a straight shape and rectifies the twisted shape created by cis bonds.

Increasing the concentrations of trans-fatty acids particularly in the red blood cell membranes can lead to blockage of the blood vessel as a whole and enhance the risk of heart disease. Meat and dairy products kind natural food materials include trans fatty acids.
