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.
If science is to be defined at,
science is a systematized body of knowledge. Science is where the organized set
of facts were obtained and is used as a tool, model or paradigm to gather such
evidential data. Science is not a fact but an existential body in which comprises
the study of the anatomy and physiology of a certain object by the means of
observation, hypothesis, experimentation, interpretation and conclusion of the
gathered facts. Or what others would describe the scientific process.
