If you have not signed up for the NASM FNS yet, you can do so here to save 20%.

If you are unsure which nutrition certification is right for you, I recommend that you take the quiz or check out my article on the top nutrition certifications. This is especially true because the FNS is slightly out of date.

Important definitions to memorize for chapter 13 of the NASM FNS

Albumin ~ A polypeptide that circulates within the blood and functions in the circulatory transport of the many minerals and a few chemical compounds

Ceruloplasmin ~ A copper-dependent catalyst responsible for the oxidation of ferrous ion (Fé+) to ferric ion (FÄ›+), enabling iron to bind to transferrin. additionally referred to as ferroxidase I

Chelation therapy ~ Use of a chelator (e.g., EDTA) to bind metal ions to get rid of them from the body

Cretinism ~ A inborn condition usually caused by severe iodine deficiency throughout gestation that is characterized by attenuated physical and mental development

Crohn’s Disease ~ A malady that causes inflammation and ulceration on sections of the internal organ tract

Cytochromes ~ heme proteins that transfer electrons within the electron transport chain through the alternate oxidation and reduction of iron

Ferric Iron (FÄ›+) ~ The oxidized form of iron able to be connected to transferrin for transport

Ferritin ~ a complex of iron and apoferritin that’s a significant storage form of iron

Ferrous Iron (Fé+) ~ The reduced kind of iron most typically found in food

Goitrogens ~ Compounds that may induce goiter

Hematocrit ~ percentage volume occupied by packed red blood cells in a centrifuged blood sample.

Heme ~ A chemical complex with a central iron atom (ferric iron FÄ›+) that forms the oxygen-binding part of hemoglobin and myoglobin

Heme Iron ~ The iron found in hemoprotein and hemoprotein of animal foods

Hemosiderin ~ an insoluble kind of storage iron

Hypogonadism ~ attenuated functional activity of the gonads (ovaries or testes) with retardation of growth and sexual development

Hypothyroidism ~ The results of a lowered level of circulating thyroid hormone, with attenuation of mental and physical functions

Keshan disease ~ Selenium-deficiency disease that impairs the structure and function of the cardiac system
