cation

A positively-charged ion–eg, Na+, K+, Ca2+, Mg2+

cat·i·on

(kat'ī-on)
An ion carrying a charge of positive electricity, therefore going to the negatively charged cathode.
[G. katiōn, going down]

cation

A positively charged atom, such as Na+ or K+, which is attracted towards a negative electrode (cathode). An atom which, in solution, takes a positive charge. Unlike charges attract; like charges repel.

Cation

An ion carrying a positive charge due to a loss of electrons. Cations in the body include sodium, potassium, magnesium, and calcium ions.

cation

positively charged ion, attracted to a negatively charged cathode

cation-anion balance
the balance in serum or plasma between the anions and cations must equilibrate near to the level of 155 mEq/l. Estimation of any imbalance, usually by chloride and bicarbonate measurement, is basic to any determination of acid-base abnormality.
cation channels
channels through selectively permeable membranes via which only cations can migrate.
dietary cation-anion difference
prepartum has a major influence on the incidence of hypocalcemia (milk fever) in dairy cattle and, in the control of the disease, is manipulated so as to result in a metabolic acidosis which facilitates the mobilization of calcium. Defined as milliequivalents of (Na+K)-(Cl+S) per kg DM diet.
cation-exchange resin
ion-exchange resin.
