What is meant by trans fatty acid?
Trans-fatty acids are manufactured fats created during a process called hydrogenation, which is aimed at stabilizing polyunsaturated oils to prevent them from becoming rancid and to keep them solid at room temperature. They may be particularly dangerous for heart health and may pose a risk for certain cancers.
What is trans fatty acids Wikipedia?
Trans fat, also called trans-unsaturated fatty acids, or trans fatty acids, is a type of unsaturated fat that naturally occurs in small amounts in meat and milk fat.
What is trans and cis fatty acids?
Cis or Trans Fatty Acids The term “cis” and “trans” describe the positions of the two hydrogen atoms located next to the carbon atoms where the double bond exists. Cis fatty acid has both hydrogen atoms located on the same side. On the contrary, trans fatty acid has the two hydrogen atoms on opposite sides.
What are examples of trans fatty acids?
The major dietary sources of trans fats are cakes, cookies, crackers, animal products, margarine, fried potatoes, potato chips, popcorn and household shortening (Table 2). Limited consumption of foods made with processed sources of trans fats provides the most effective means of reducing intake of trans fats.
Where are trans fatty acids?
Trans fatty acids are found in many ready-made foods at grocery stores and in many items at fast-food restaurants. Vegetable shortening and margarine are composed primarily of hydrogenated oils.
Why is it called trans fat?
History of trans fat In 1901 German chemist Wilhelm Normann experimented with hydrogenation catalysts and successfully induced the hydrogenation of liquid fat, producing semisolid fat, which came to be known as trans fat.
What are the properties of trans fatty acids?
Trans fatty acids are unsaturated fatty acids; however, they contain at least one double bond in the “trans” configuration, the thing that makes them more similar to saturated than unsaturated fat. Trans fatty acids are solid at room temperature and occur, in small amounts, naturally in some food.
How are trans fatty acids made?
Most of the trans fat in the foods we eat is formed through a manufacturing process that adds hydrogen to vegetable oil, which converts the liquid into a solid fat at room temperature. This process is called hydrogenation.
What is the difference between cis and trans?
What Is Cisgender? Cisgender, or cis, means that the gender you identify with matches the sex assigned to you at birth. Transgender is when your gender identity differs from the sex on your birth certificate. In Latin, “cis” means “on this side,” while “trans” means “on the other side.”
What is the difference between trans fats and saturated fats?
The main difference between trans fat and saturated fat is that trans fat raises low-density lipoprotein (LDL) levels and drops high-density lipoprotein (HDL) levels in the blood whereas saturated fat raises both LDL and HDL levels in the blood.
