SAS Lipids Flashcards
Ketone bodies may be exported to other tissues, used for?
Energy production
Some cells synthesized fatty acids for?
Storage or export
Based on biochemical function lipids are divided into five categories:
- Energy storage lipids
- membrane lipids
- emulsification lipids
- messenger lipids
- protective-coating lipids
When the bed is placed in a basic aqueous solution lipitor divided into categories:
Saponifiable lipids and non saponifiable lipids
Are converted into smaller molecules when hydrolysis occurs
Saponifiable lipids
Cannot be broken down up into smaller units since they do not react with water
Nonsaponifiable lipids
What are the five categories of lipids based on chemical reaction
Energy storage lipids
Membrane lipids
Emulsification lipids
Messenger lipids
Protective coating lipids
The building blocks of lipids in our naturally occurring monocarboxylic acid
Fatty acids
Is a fatty acid with a carbon chain in which all carbon-carbon bonds are single bonds
Saturated fatty acids
The aka BAD fat dietary effect is an increase in heart disease risk
Saturated fatty acids
Is a fatty acid with a carbon chain in which one carbon-carbon double bond is present
Monounsaturated fatty acids
Aka the GOOD fat, dietary effect is a decrease in heart disease risk
Monounsaturated fatty acids
Fatty acid with a carbon chain in which two or more carbon-carbon double bonds are present
Polyunsaturated fatty acids
Dietary effect is mixed:
GOOD fat - it decreases heart disease risk
BAD fat - increases cancerous
Polyunsaturated fatty acids
What are the configuration of double bond in lipids?
-cis
-trans
What are the locations of double bonds
Omega-3 and omega-6
Is a fatty acid needed in the human body that must be obtained from dietary sources because it cannot be the synthesized within the body
Essential fatty acids
- Primary member of omega 6 fatty acids
- It is from vegetable oil
- Decreases plasma cholesterol and decreases HDL
Linoleic Acid (18:2)
Primary member of the omega-3 fatty acids
it is found in plants
Linolenic acid (18:3)
Most abundant type of lipids present in the body and remain storage form of fatty acids
Triacyglycerols
What are the two types of triacyglycerols?
Simple and mixed triacylglycerols
Is a triester formed from the esterification of glycerol with three identical fatty acids molecule
Simple triacyllglycerol
A triester formed from the esterfication of glycerol with more than one kind of fatty acid molecules
Mixed triacylglycerols
Is a triangle mixture that is a solid or semi solid at room temperature 25 degree celcius
Fat
Is a triacylglycerol mixture that is a liquid at room temperature 25° C
Oil
Means less than 0.5 g of fat per serving
Fat free
Means 3g or less fat per 50g serving
Low fat
Means at least 25% less fat per serving than the regular food
less fat
Means less than 0.5 kilo calories per serving
Calorie free
