Cards

Term
Vitamin A
Definition
Responsible for pigments, coloration, eye and reproductive health, bone development
Term
Carotenoids: Carotenes
Definition
Converts into Vitamin A. Alpha and Beta carotene, Lycopene. Plant form
Term
Carotenoids: Xanthophylls
Definition
No vitamin A conversion, but promotes pigmentation. Lutein, Zeaxanthin
Term
Characteristics of Fat Soluble Vit.
Definition
Stored in liver, adipose tissue. Too much can be toxic. Stronger in processing. AD most toxic. EK least toxic. Deficiency rare
Term
Characteristics of Water Soluble Vit.
Definition
No storage, less toxic. Loss in processing. Deficiency fast.
Term
Vitamin D
Definition
Sunshine vitamin. Vitamin D2 plant, Vitamin D3 animal form. Regulates blood Ca by regulating absorption.
Term
Vitamin D hormone: Calcitonin
Definition
Produced in thyroid gland. Kicks in when blood Ca is too high, stores it in bone and decreases absorption
Term
Vitamin D hormone: Parathyroid hormone
Definition
Kicks in when blood Ca is too low. Mobilizes Ca from the bones, and stimulates kidney to activate Vit. D to increase absorption.
Term
Vitamin E
Definition
Antioxidant function. Decreases effect of oxygen species and amount of free radicals. Paired up with selenium to make the cell membrane stronger.
Term
Vitamin K
Definition
Essential for blood clotting.
Term
Thiamin
Definition
Supplies enzymes to produce pyruvate --> acetyl CoA
Term
Riboflavin
Definition
Functions in carbohydrates,lipid and protein metabolism.
Term
Niacin
Definition
Component of NAD and NADP, oxidation-reduction rxn, H transfer.
Term
Pantothenic Acid
Definition
Constitute of Acetyl-CoA and fatty acid CoA, transfers to cells to jumpstart rxns.
Term
Pyridoxine (B6)
Definition
Amino acid metabolism. Transanimation and Decarboxylation.
Term
Folic Acid
Definition
Synthesis of purine and thymidine to produce red blood cells, GI tract cells, transfers methyl groups
Term
Vitamin B12:Cyno-cobalamin
Definition
Methyl transfer, related to folic acid.
Term
Choline
Definition
Involved with fat synthesis, transport, and metabolism.
Term
Biotin
Definition
Carb and fatty acid metabolism
Term
Vitamin C
Definition
Antioxidant properties, req. for only few species, collagen synthesis.
Term
Macro minerals
Definition
Ca, P, Mg, Na, K, Cl, S
Term
Micro Minerals
Definition
Mn, Zn, Fe, Cu, Mo, Se, I, Co, Cr
Term
Calcium
Definition
Skeletal, Muscle contration, Blood coagulation. Formation and continuous growth of collagen, bone.
Term
Osteoclast
Definition
Breaks down/reabsorbs bone cells
Term
Osteoblasts
Definition
Bone formation
Term
Regulation of blood Ca and P levels are done by
Definition
PTH, Calcitonin, Vitamin D
Term
Hypocalcemia
Definition
Low blood Ca. PTH released from parathyroid gland to
Increase of P excretion. Ca Resorption and mobilization of Bone Ca, Vitamin D synthesis.
Term
Hypercalcemia
Definition
High blood Ca. Calcitonin reverse affects of PTH hormone. Bone mobilization reduced, Ca excreted
Term
Phosphorus
Definition
Involved in structural and metabolic activities. Commonly paired up with Ca.
Term
Phosphorus-phytate complex
Definition
P in plant form. Hard to break up, making it easily excreted. Phytase enzyme used make P-phytate usable.
Term
Magnesium
Definition
3rd most abundant. Functions in energy metabolism, enzyme activation, skeletal development.
Term
Electrolytes: Na+, K+, Cl-
Definition
Carrier for minerals, involved with metabolism, maintenance of osmotic pressure, membranes and acid-base balance.
Term
Sodium
Definition
Na+ main extra cellular cation
transport of nutrients, channels, muscle contraction
Term
Chlorine
Definition
Cl- Extra cellular anion. Regulates osmotic pressure.
Term
Potassium
Definition
K+ intracellular cation. Regulates osmotic pressure and is a component of the Na pump
Term
Sulfur
Definition
Component of organic bio molecules (enzymes, proteins, amino acids, vitamins), fur and skin quality, collagen and connective tissue.
Term
Iron
Definition
Oxygen carrier in blood and muscle (transferrin). Has two Oxidation states: Fe II and Fe III.
Term
Ferritin
Definition
Storage form of Fe. Soluble and readily available. Stored in the liver, spleen, bone marrow
Term
Hemosiderin
Definition
Insoluble, not readily available.
Term
Copper
Definition
Two oxidation states: Cuprous (Cu I) and Cupric (Cu II)
Required for red blood cell formation. Involved in formation of collagen and elastin. Fur pigmentation.
Term
Ceruloplasmin
Definition
Transport form of Cu
Term
Iodine
Definition
Involved with thyroxin, a thyroid gland hormone that regulates basal metabolic rate.
TSH: increase uptake of I. Secreted by anterior pituitary gland.
Term
Thyroglobulin
Definition
Storage form of I
Term
Selenium
Definition
Found mostly in muscle and liver. Antioxidant which works alongside Vitamin E. Se more important for ruminants.
Term
Cobalt
Definition
Used by microbes to produce vitamin B12.
Term
Manganese
Definition
Concentrated in the bone. Maintains and produces bone matrices. Involved with CHO, protein, and lipid metabolism.
Term
Zinc
Definition
Component of metalloenzymes, widely distributed throughout the body. Binds to albumin for transport.
Term
Mo
Definition
Cofactor for enzyme systems
