Essential Nutrients An essential nutrient is a nutrient required for normal body functioning that either cannot be synthesized by the body at all‚ or cannot be synthesized in amounts adequate for good health (e.g. niacin‚ choline)‚ and thus must be obtained from a dietary source. Essential nutrients are also defined by the collective physiological evidence for their importance in the diet‚ as represented in e.g. US government approved tables for Dietary Reference Intake.

PROJECT IN CHEM LAB. Submitted by: BHEA MARIE MENDOZA Submitted to: -CATIONS and ANIONS- Cations are positive charged ions. A cation has fewer electrons than protons. Anions are negatively charged ions. An anion has more electron than protons. The nature and magnitude of charge on ion depend on the position of an element in the periodic table. In forming an ion‚ an atom of a main group element loses gains electrons to obtain the electronic configuration of the noble gas
