unit 2: essential, trace, and non-essential elements Flashcards
________: any atom or group of atoms that bears one or more positive or negative electrical charges.
- formed by the addition of electrons to, or the removal of electrons from, neutral atoms or molecules or other ions; by combination of ions with other particles.
ions
________: widely used in biochemical functions.
________: study of chemistry of living organism (plants and/or animals). Whereas the branch of chemistry in which significant role of metal ions in biological systems are covered by _______ chemistry.
- ions
- Biochemistry
- bioinorganic
- Important source of energy
- Includes protein, fat and carbohydrates
MACRO
- bulk structural elements
- C, H, O, N, P, S - macro mineral elements
- Na, K, Mg, Ca, Cl
- Includes electrolytes
- Essential to fulfill important metabolic function
- Supports enzymes and hormones (cofactors)
MICRO
- Trace (mg/L)
- Fe, Cu, Zn, V, Ni, Cd, Li, Pb, Sn - Ultra trace (μg/L)
- Metals: Mn, Mo, Co, Cr, Si, As, Se, Ba
- Non-metals: F, I, B
- Elements (chemistry) or dietary element (biology) found/needed in very small quantities or concentrations
- Has a specific role for maintaining normal living state of the tissue or body, the absence or deficiency of these elements results in death or a severe malfunction of the organism
CRITERIA:
- Should be present in tissues at comparable concentration
- Its withdrawal should produce some physiological or structural abnormalities
- presence prevents abnormalities
- The function of the element cannot be totally performed by any other element
ESSENTIAL (Bulk structural, macro mineral, and trace elements)
Elements that have no known biological function and exposure to some may cause adverse health consequences
NON-ESSENTIAL (some of ultra trace elements)
