Understanding Nutrition Chapter 13| Questions
with 100% Correct Answers
hematocrit (hee-MAT-oh-krit) - ✔️✔️measurement of the volume of the red blood
cells packed by centrifuge in a given volume of blood.
heme iron (HEEM) - ✔️✔️the iron in foods that is bound to the hemoglobin and
myoglobin proteins; found only in meat, fish, and poultry.
hemochromatosis (HE-moh-KRO-ma-toe-sis) - ✔️✔️a genetically determined
failure to prevent absorption of unneeded dietary iron that is characterized by iron
overload and tissue damage.
hemoglobin - ✔️✔️the oxygen-carrying protein of the red blood cells that transports
oxygen from the lungs to tissues throughout the body; hemoglobin accounts for 80
percent of the body's iron.
hemosiderin (heem-oh-SID-er-in) - ✔️✔️an iron-storage protein primarily made in
times of iron overload.
hemosiderosis (HE-moh-sid-er-OH-sis) - ✔️✔️a condition characterized by the
deposition of hemosiderin in the liver and other tissues.
hepcidin - ✔️✔️a hormone produced by the liver that regulates iron balance.
iodine - ✔️✔️an essential trace mineral that is needed for the synthesis of thyroid
hormones.
iron - ✔️✔️an essential trace mineral that is needed for the transport of oxygen and
the metabolism of energy nutrients.
iron deficiency - ✔️✔️the state of having depleted iron stores.
iron overload - ✔️✔️toxicity from excess iron.
, iron-deficiency anemia - ✔️✔️severe depletion of iron stores that results in low
hemoglobin and small, pale red blood cells. Anemias that impair hemoglobin
synthesis are microcytic (small cell).
Keshan (KESH-an or ka-SHAWN) disease - ✔️✔️the heart disease associated with
selenium deficiency; named for one of the provinces of China where it was first
studied. Keshan disease is characterized by heart enlargement and insufficiency;
fibrous tissue replaces the muscle tissue that normally composes the middle layer
of the walls of the heart.
lignans - ✔️✔️phytochemicals present in flaxseed, but not in flax oil, that are
converted to phytosterols by intestinal bacteria and are under study as possible
anticancer agents.
lutein (LOO-teen) - ✔️✔️a plant pigment of yellow hue; a phytochemical believed to
play roles in eye functioning and health.
lycopene (LYE-koh-peen) - ✔️✔️a pigment responsible for the red color of tomatoes
and other red-hued vegetables; a phytochemical that may act as an antioxidant in
the body.
manganese - ✔️✔️an essential trace mineral that acts as a cofactor for many
enzymes.
Menkes disease - ✔️✔️a genetic disorder of copper transport that creates a copper
deficiency and results in mental retardation, poor muscle tone, seizures, brittle
kinky hair, and failure to thrive.
metalloenzymes (meh-tal-oh-EN-zimes) - ✔️✔️enzymes that contain one or more
minerals as part of their structures.
metallothionein (meh-TAL-oh-THIGH-oh-neen) - ✔️✔️a sulfur-rich protein that
avidly binds with and transports metals such as zinc.
MFP factor - ✔️✔️a peptide released during the digestion of meat, fish, and poultry
that enhances nonheme iron absorption.
