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

<u>Explanation:</u>

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.

Trans-fatty acids:

1  often created by treating plant oils with hydrogen  is a true statement

2 cause the shape of fatty acids to be incorrect  is a false statement

3 help membranes function normally  is a false statement

4 occur naturally in in food is a true statement

Explanation:

Trans-fatty acids are unsaturated fatty acids obtained due to addition of a hydrogen molecule to vegetable oils by a process called hydrogenation.

The shape of fatty acids changes due to the hydrogenation process. The trans configuration of the unsaturated fatty acids gain one conjugated double bond and obtain a straight shape and corrects the bent shape formed due to cis bonds.

An increase in the trans-fatty acid levels especially in the membranes of the red blood cells will lead to clogging of the blood vessel itself and increases the risk for cardiac diseases. Trans fatty acids reduce the flexibility of the cell membranes and make it more rigid. The cell membranes should be flexible and the cellular molecules should be fluid for easy cellular transport of materials.

Natural foods like meat, dairy products contain trans fatty acids.

Is there a scientific reason why adults don't really understand their children?
Alenkinab [10]
Throughout their teenage years, children's minds are literally being rewired. Teenagers are unable to comprehend facial expressions or other's emotions which can make it for others to understand them or for them to even understand themselves.
