Document Summary
Understand factors impacting the bioavalibility of zinc. Understand links between zinc status and health outcomes. Rda: men: 11 mg/day, women: 8 mg/day. Pancreas produces zinc binding ligand (zbl) called picolinic acid: enteropancreatic zinc recirculation, we can recirculate zinc and iron. Above rda: takes a while to digest and reuse. Breast milk contains zinc-picolinate: formulas have zinc, but not all zinc picolinate (zinc bound with picolinic acid) Cofactor in proteolytic enzymes: enzymes that break down proteins have zinc as a component of them. Acid-base balance (carbonic anhydrase: zinc is a component of the enzyme that favors this balanced process. Cofactor, lactate dehydrogenase: glycolysis, body goes to use glucose in oxidative cycle. Wound healing: dna expression, cellular growth and differentiation, t-lymphocytes need zinc to be made. Wbcs that are important in immune function. Reduction of growth in children (sexual development) Produce sufficient zinc but don"t produce a certain ligand. Decrease risk macular degeneration? (opaque portion of cornea: central vision.
