mc2 lipids n carbo Flashcards
are fatty, waxy, or oily compounds that are soluble in
organic solvents and insoluble in polar solvents such as water.
lipids
5 properties of lipids
pure fats and oil are colorless
odorless and tasteless
have no ionic charges
insoluble in water
soluble in organic solvents
classifications of lipids
saponifiable lipids
non-sapnonifiable lipids
has one or more ester groups that allow it
to be hydrolyzed in the presence of a base, acid, or enzymes
saponifiable lipids
an organic chemical process where
an ester is broken down into a
carboxylic acid and alcohol using an
alkali.
saponification
cannot be
hydrolyzed into smaller molecules
non-saponifiable lipids
2 types of lipids
simple lipids
complex lipids
Esters of fatty acids containing
fatty acids and glycerol/ alcohol.
simple lipids
Esters of fatty acids composed of
groups of lipids including fatty acids,
alcohols and others like phosphate,
proteins, carbohydrates, etc.
complex lipids
2 major classes of glycolipids
glycoglycerolipids
glycosphingolipids
composed of :
2 major (fatty acids and glycerol)
+ carcohydrates
glycoglycerolipids
composed of :
1 major (fatty acids)
+carcohydrates + sphingosine
glycospingolypids
are “esters,
“ which are organic compounds created by
substituting an alkyl or another chemical group for the hydrogen
atom in an acidic substance.
waxes
is a type of lipid molecule that is the main component
of the cell membrane.
phospholipids
is a type of hormone that can be identified by its
tetracyclic structure, which is made up of three fused sixmembered rings and one five-membered ring
steroids
