Lipids Structure And Digestion Flashcards
Lipids are components of?
plants and animal tissues
On a physical nature, lipids are relatively insoluble in?
water
On a physical nature, lipids are soluble in?
organic solvents, such as hexane, ether, and chloroform
Chemically, lipids are organic compounds and esters of?
fatty acids and glycerol (a 3 C compound) or some other alcohol.
(a 3 C compound)
glycerol
are the primary storage form of energy (e.g., oil in seed) and serve as an animal’s body’s “savings account.”
Fats
the abdominal fat pads in chicken and back fat in pigs are mostly?
triglycerides
Esters of fatty acid with alcohol
Simple lipid
what is the molecular structure of triglycerides
1 glycerol + 3 fatty acids
Compounds of lipids:
A. Glycolipid
B. Lipoproteins
C. Phospholipids
Lipid Classifications:
A. Simple lipid
B. Compound
C. Derived Lipids
like triglycerides are more common and are an important component in animal rations (e.g., vegetable oil and animal fats such as tallow or lard).
Simple lipids
are composed of a lipid plus a nonlipid molecule
Compound lipids
(lipid + protein)
Lipoprotein
Lipoprotein (lipid + protein) are examples of compound lipids and are used for?
lipid transport
Within the animal body, compound lipids are more important in?
physiology and metabolism
Nutritionally, ? are excellent sources of energy and are essential to the survival of animals.
fats
Fats are the sole source of (those that cannot be made by the body) for animals
Essential fatty acids
can also provide fat-soluble vitamins.
Fats
very minimal in livestock because feeds are supplemented with?
vitamins
The most important role of dietary fat is to provide
essential fatty acids
As the fat content of the diet increases, the ? of the diet goes up.
energy density
Physically, the addition of fats is associated with the improvement of?
feed quality
Physically, the addition of fats is associated with the reduction of dust in?
feed
