NUTR 119 Study Guide - Midterm Guide: Trans Fat, Monounsaturated Fat, Emulsion
Fats and Oils
· What are the building blocks of fats/lipids?
Fatty acids are the key building blocks of lipids
· What is the difference between saturated, monounsaturated and
polyunsaturated fats? How many double bonds are present (and/or lacking in
each of the fats)?
Saturated fats → there are no double bonds between carbons
Monounsaturated → when one double bond is present
Polyunsaturated → when two or more double bonds are present
· What are “good” fats, “bad” fats?
Good fat → helps lower cholesterol, reduces risk of CVD
Bad fat → raises cholesterol, increases risk of CVD
· What is a phospholipid? What do eggs contain that make it a good
emulsifier?
Phospholipid → egg yolks
· What is the process of hydrogenation? What is an example of a
hydrogenated fat?
Process in which hydrogen molecules are added to liquid oils to reduce the
number of double bonds, improves the ability to spread, trans fat
· What are trans fats? What is the difference between a “trans” vs. “cis” fatty
acid?
THE UGLY contains double bond, “cis” more common than “trans” “cis”=naturally
occurring form
