The correct answer is "trans fatty acids".
Trans fatty acids (colloquially as trans fats) are a type of unsaturated fatty acids wherein instead having its double bonds in the cis configuration giving the fatty acid "kinks" in the molecules making it more soluble; the double bonds in trans fats are in the trans configuration (hence the name) and this will not give the molecule kinks making it less soluble. Less soluble trans fats are notorious in depositing in peripheral arteries as well as in coronary arteries that increase the risk for developing atherosclerosis.
Answer:
True. You can get vitamin A as "preformed vitamin A" which is already active and/or you can get vitamin A as carotenoids which the body can turn into active vitamin A.
Explanation:
There are two different types of vitamin A that can be obtained from food:
1. Preformed vitamin A, which is already active, is found in animal products such as beef, fish, poultry and dairy products.
2. Provitamin A, which is the inactive form, is found in plant-based foods, such as fruits and vegetables. The most common type of provitamin A is β-carotene, which is a carotenoid that the body can turn into active vitamin A via an enzyme named β-carotene 15,15'-monooxygenase.
