Document Summary

Water balance: we do not store water in the body, so each day water losses approximately equal water gains. Functions of water: solvent, primary constituent of blood, environment for chemical reactions, metabolism and transport, protection, lubrication, tears, cushioning, hydrolysis/dehydration reactions, regulation of body temperature. Meeting: inorganic elements found on the periodic table, throughout nature, >20. Mineral bioavailability: depends on the source (ex. soil quality of where plants are grown), what else is eaten at the same time, the preparation and the individual, i(cid:374) ge(cid:374)eral, (cid:373)i(cid:374)erals . Phttates (cid:272)a(cid:374) (cid:271)e (cid:271)roke(cid:374) : some minerals can fnction as cofactors, activating enzymes, the mineral cofactor combines with the incomplete enzyme to form the active enzyme, the active enzyme binds to the. Sodium, potassium, chloride: charged ions (+ve/-ve) that are responsivle for the electrical activity of the body, sodium= main extracellular ion, potassium=main intracellular one, also regulate fluid balance, deficiency typically associated with excessive sweating, diarrhea, vomiting.
