Question:
T/F: If false, explain why it is false

together

false - the type of fatty acid is dependent on the bonds that link carbon units
together
,Question:
simplest form of fats
Answer:
fatty acids
Question:
saturated vs unsaturated fatty acid
Answer:
a) saturated - no carbon double bond
b) unsaturated - at lease one carbon double bond
Question:
3 types of unsaturated fatty acids
Answer:
mono-unsaturated, poly-unsaturated, trans-unsaturated
Question:
Monounsaturated Fatty Acids
Answer:
Fatty acids with one double bond.
,Question:
Polyunsaturated Fatty Acids
Answer:
more than one double bond
Question:
trans unsaturated fatty acids
Answer:
found in food products such as stick margarine, shortening, and deep-fried
foods. Trans fats are a type of partially hydrogenated unsaturated fat that is
largely a byproduct of the food industry.
Question:
_____ were recently determined to have a significantly higher impact on
raising cholesterol levels than saturated fats. Importantly, foods can contain
varying amounts of the different types of fatty acids. Fats in foods are
therefore classified based on which fatty acid is present in the highest
concentration.
Answer:
trans fatty acids
, Question:
triglyceride
Answer:
the major form of fats in our body and in our diet. A triglyceride is formed
when three fatty acids bond together with a glycerol molecule, potential
source of energy, provide insulation/protection, serve as carrier of fat soluble
vitamins, and improve taste of food
Question:
phospholipid
Answer:
play an important role in the formation of cell membranes, are used to
transport lipoproteins, and also act as emulsifiers (as will be discussed later in
this module). Consist of (1) a phosphate group, also known as the head group,
and (2) two fatty acid chains, also known as the tail group. two groups are
linked together by glycerol
Question:
sterol
Answer:
class of lipid that includes hormones (steroids) and cholesterol, the most
common sterol, no glycerol, backbone, necessary in production of several
hormones and bile acids
