Lipids: The Role of Triglycerides Flashcards
What are triglycerides commonly know as?
Fats and oils
What is the main diff between fats and oils
Fats are solid at room temp.
Oils are liquid at room temp.
What causes the difference in state between fats and oils?
presence of double bonds between carbon atoms in the hydrocarbon chain
Fatty acids with no double bonds in the hydrocarbon chain are called……..?
Saturated Fatty acids
Fatty acids that have 1 double bond between carbon atoms in the hydrocarbon chain are………….
Monounsaturated Fatty acids
Fatty acids that have many double bonds between carbon atoms in the hydrocarbon chain are ……………..
Polyunsaturated
What is the effect of presence of double bonds in a hydrocarbon chain of a fatty acid
It causes the fatty acids to bend
What does the bending in fatty acids do ?
It pushes the triglyceride molecules farther apart from each other than in saturated triglycerides
Why are unsaturated triglycerides liquid at room temperature?
molecules are farther apart and intermolecular forces weaken
Which reaction forms Atp?
Aerobic respiration
What do we get from ATP
our energy which we use in (suitable example eg: movement, muscle contraction)
Triglycerides can also be broken down into …………. and …………….. to be used in ………..
-Glycerol
-Fatty acids
-Respiration
Do Triglycerides release large or small amount of energy?
Large amount
Why do triglycerides release large amt of energy?
Due to the large amount of Carbon-Hydrogen bonds broken down in the hydrocarbon chain
Triglycerides are a good source of …………….. for ……………… reactions.
Water
Metabolic
