Lipids 1 Flashcards
They are organic compounds found in living organisms that are insoluble (or only sparingly soluble) in water, but soluble in non-polar organic solvents
LIPIDS
Lipids that are naturally occurring monocarboxylic acids; are carboxylic acids
with linear (unbranched) aliphatic chain
FATTY ACIDS
it indicates number of C atoms
and number of double bond
Structural notation
What are the unsaturated fatty acids
Oleic
Linoleic
Linolenic
Arachidonic
It Must be part of the diet Children need it the most Human milk has more EFA than cow’s milk
ESSENTIAL FATTY ACIDS
What are the examples of ESSENTIAL FATTY ACIDS
Linoleic acid (Omega-6)
Linolenic acid (Omega-3)
Short chain fatty acids have
some ________ whereas long
chain fatty acids are ________
Solubility
Insoluble
The ________ number of C atoms,
________ melting point
Higher
Higher
The ________ degree of unsaturation,
__________melting point
Higher
Lower
Lipids that are Concentrated primarily in
adipocytes and are considered as Energy-storage materials
TRIGLYCERIDES
Triacylglycerols that has three identical fatty acids are esterified; naturally occurring simple TAGs are rare
Simple Triacylglycerols
Triacylglycerols that is a tri-ester formed from the esterification of glycerol with more than one kind of fatty acid
Mixed Triacylglycerols
Triacylglycerols state that is made of saturated fats, usually from animal sources
FATS
Triacylglycerols that is made of unsaturated fats, usually from plant source
Oils
Simple lipids that are Protective-coating materials and are a Monoester of a long-chain FA and a long-chain alcohol
BIOLOGICAL WAXES
Lipids with other components than in triglycerides; may be composed of mono- or diacylglycerols, sterols, sphingolipids, etc.
COMPOUND LIPIDS
3 Types of Compound Lipids
MEMBRANE LIPIDS
EMULSIFICATION LIPIDS
MESSENGER LIPIDS
What are the components of Membrane Lipids
Phospholipids
Sphingolipids
Cholesterols
Chemical composition of PHOSPHOLIPIDS

PHOSPHOLIPIDS has the organic molecule _______
Alcohol
Chemical composition of SPINGOLIPIDS
Sphingosine
Fatty acid
Phosphate
SPINGOLIPIDS has the organic molecule __________
Ceramide
SPINGOLIPIDS that are related to cerebrosides that contain sphingosine, long- chain fatty
acids, hexoses (usually galactose or glucose), and neuraminic acid
Ganglioside
Increase in Ganglioside leads to what disease?
TAY SACH’S DISEASE
