NUTRI - FATS Flashcards
Are organic compounds composed of carbon, hydrogen, & oxygen.
FATS
or fats and oils are fatty acids ester of glycerol.
TRIGLYCERIDES
It constitutes 34% of the energy in the human body, including substances such as fats, oils, waxes, & related compounds that are greasy to the touch & insoluble in water.
FATS
They provide a more concentrated source of energy compared to carbohydrates.
FATS
Some fat deposits are not used & are considered _______ – they hold the body organs & nerves in position & protect them against shock & injury.
structural fat
Chemical name: triglycerides – indicates chemical structure, a glycerol base with 3 fatty acids attached. Glycerol is derived from a water-soluble form of carbohydrates.
SIMPLE LIPIDS / NEUTRAL FATS
Waxes are esters of fatty acids with higher molecular weight alcohol. They are classified into sterol & non-sterol esters.
SIMPLE LIPIDS / NEUTRAL FATS
various combinations of fats with other components.
COMPOUND LIPIDS
compounds of fatty acids, phosphoric acids & nitrogenous bases.
PHOSPHOLIPIDS
the most widely distributed of the phospholipids. Traces are placed in liver & egg yolk & in raw vegetable oils (corn oil). They are added to food products (cheese, margarine, & confections to aid emulsification).
LECITHINS
needed to form thromboplastin for the blood clotting process.
CEPHALINS
found in the brain & other nerve tissues as components of myelin sheath. Three substances acts as an insulator around the nerve fibers. Egg yolk & liver are good sources of these phospholipids.
SPHINGOMYELINS
fatty acids combined with carbohydrates & nitrogenous base.
GLYCOLIPIDS
are components of nerve tissue & certain cell membranes where they play vital roles in fat transport. Their carbohydrate component is galactose.
CEREBROSIDES
made from certain glucose, galactose, & a complex compound containing an amino sugar.
GANGLIOSIDES
