LIPIDS Flashcards
(31 cards)
Are the primary storage form of energy (e.g., oil in seed) and serve as an animal’s body’s “savings account.”
FATS
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 (e.g., protein).
COMPOUND LIPIDS
Family of fatty acid that contain one or more double bonds between adjacent carbon atoms in the hydrocarbon chain
UNSATURATED FATTY ACID
Are the main players in lipid nutrition. This is due to their diversity in structure, composition, and metabolizability.
FATTY ACIDS
Is a trans fatty acid present in cow’s milk or other ruminant food like beef and is produced by rumen microbes during the biohydrogenation process
CONJUGATED LINOLEIC ACID
Are the most abundant steroid in the human diet
STEROLS
Is the best-known steroid (fat-soluble substance containing a steroid nucleus) and is the precursor of many other substances such as vitamin D, bile acids, sex hormones, and corticosteroid hormones.
CHOLESTEROL
Serve as energy reserves for the plant (seeds) or animal (fat depots).
TRIGLYCERIDES
It is the dispersion of lipids in small droplets
EMULSIFICATION
____________________ of unsaturated fatty acids is the second major transformation that dietary lipids can undergo in the rumen
BIOHYDROGENATION
Are temporary compounds formed during the fat digestion and absorption process
MICELLES
It is called the reuse of bile salt for fat digestion
BILE SALT RECYCLING
These are temporary compounds (e.g., micelles) that is formed during lipid absorption.
CHYLOMICRONS
Consists of an inner core of hydrophobic lipids surrounded by a surface layer of phospholipids, cholesterol, and outer proteins (apolipoprotein).
LIPOPROTIENS
Is the process of synthesizing lipids as a means of storing chemical energy
LIPOGENESIS
Is a metabolic disorder when excessive quantities of ketone bodies are produced
KETOSIS
The location of fatty acid synthesis.
JEJUNUM
The starting material of fatty acid synthesis
ACETYL CoA
Esters of fatty acid with alcohol, e.g., 1 glycerol + 3 fatty acids (commonly called triglyceride or triacylglycerol
LIPIDS
Are examples di compound lipids and are used for lipid transport (like a courier)
LIPOPROTEIN
Other term for triglycerides.
TRIACYLGLYCEROL
Is the most abundant steroid present in animal tissue and serves as a precursor for vitamin D, bile acids and steroid hormones.
CHOLESTEROL
Are acted upon by enzyme pancreatic lipase and converted into fatty acids, monoglycerides and glycerol
EMULSIFIED LIPIDS
