Module 4 Flashcards
Sugars
Saturated
fatty acids with single bonds between carbons
Unsaturated
fatty acids with at least one double bond between carbons
Trans-fats
modified fatty acids for processed foods by flipping hydrogens
Omega-3
fatty acids thought to benefit health
Sugars contain…
carbon, hydrogen, oxygen
The important cholesterol-based lipids for regulation are…
steroids
The structural lipid family which is “bipolar” or amphipathic is…
phospholipids
The stored carbohydrate that is used to correct low blood glucose is…
Liver glycogen
Lipids high in saturated fatty acids are principally found in what food source
animal and some tropical plants
The lipid family with the primary function of regulation would be…
steroids
a plant carbohydrate that provides calories to ruminants like cattle, is not digestible by humans is…
cellulose
Foods considered to have high glycemic index can…
cause a rapid rise in blood glucose, followed by a rapid fall
T/F Table sugar is a di-saccharide of glucose and frutose
True
T/F Diets high in Omega-6 fatty acids are the healthiest diets
False
T/F Saturated fats are less healthy than unsaturated because they are more calorie dense
False
what are the four types of macromolecule families
carbohydrates, lipids, proteins, nucleic acids
which macromolecules are used for energy
carbohydrates family
what molecule is essential for brain food
glucose
what are the effects on blood glucose and health
high glycemic index foods quickly digest and absorb causing rapid rise in blood pressure
what are the physical properties of saturated and unsaturated acids
saturated is solid at room temp and unsaturated is liquid at room temp
what are the food sources of saturated, unsaturated, and trans acids
saturated is animals and some tropical plant foods, unsaturated is plants and some cold-water fish foods, and trans is either industrial or natural sources
