Week 4 Ch 10: Nutrients present in calcified structures

copper

formation of rbc and connective tissues; catalyst in formation of collagen; encourage production of NTs (NE and dopamine)

Wilson’s disease

metabolic disorder in which large amounts of copper accumulate in liver, kidney, brain and cornea - causes brown/green ring called Kayser-Fleischer ring

selenium

cofactor for antioxidant enzyme that protects membrane lipids, proteins and nucleic acids from oxidative damage; present in tooth enamel and dentin - large amounts may be detrimental to mineralization

chromium

carbs and lipid metabolism; potentiates the action of insulin

manganese

involved in enzyme systems for - optimal bone matrix development, insulin production, AA, cholesterol and carbs metabolism

molybdenum

enzyme cofactor; trace element present in teeth, may inhibit caries

boron

may have effect on metabolism of calcium, phosphorus, magnesium or vit D; may be needed to maintain membrane structure

nickel

unclear, may be involved in vit b12 metabolism; sources - dried beans, peas, grains, nuts and chocolate

silicon

role in structure and resilience of collagen, elastic and polysaccharides; sources - whole grains, root vegetables

tin

utilization of calcium and zinc and may affect bone growth and maintenance

lithium

accumulates in bone and decreases calcium content; increase in acid solubility

vanadium

incorporated in bones and dentin during rapid mineralization; sources - shellfish, mushrooms and parsley

aluminum

not essential nutrients, presence in body appears to be harmful; accumulation in bone has been observed to cause osteodystrophy; may reduce caries
