Essential minerals

Minerals. Nuts are considered to be a good source of minerals essential for nutrition, supplying elements of copper, manganese, iron, and sulfur (see Mineral nutrients). The values for the mineral constituents of many nuts shown in Table 2 are averages of available analytical data. Values for the mineral content of the peanut kernel (28) and ash constituents in the macadamia kernel (29) and cashew (26) have also been reported. Chufa nuts have a high sihcon content. 

Mineral-kermes, m. kermes mineral, -laugen-salz, n. Old Chem.) sodium carbonate, -mohr, m. ethiops mineral (essentially amorphous HgS). 

What do the ions of the following elements have in common calcium, Ca chlorine. Cl chromium, Cr cobalt, Co copper, Cu fluorine, F iodine, I iron, Fe magnesium. Mg manganese, Mn molybdenum, Mo nickel, Ni phosphorus, P potassium. K selenium, Se sodium, Na sulfur, S zinc, Zn They are all dietary minerals essential for good health, but can be harmful, even lethal, when consumed in excessive amounts. 

It was stated that hydrated calcium monohydrogen phosphate in amorphous or cryptocrystalline form is a potential precursor in the formation of hydroxyapatite because the structural position of Ca2+ on (010) and (110) crystal planes of both minerals essentially correspond to one another492. These planes of calcium ions could easily serve as transition boundaries with little distortion of crystal structure the same holds true for octacalcium phosphate or defect apatites. Thus apatite may form from amorphous or microcrystalline calcium monohydrogen phosphate possible via octacalcium phosphate or defect apatites. This process may already start inside the matrix vesicles and continue during extravesicular activities. 

Each of these minerals participate in a variety of biologic functions and is necessary for normal metabolism. Other trace minerals essential to humans but for which deficiency states have not been recognized include nickel, vanadium, cobalt, and silicon (Table 66.2). 

The original sediment had a complex composition which was determined by fluctuations in Eh, pH, Pqq, etc. in the sedimentary basin. Magnetite and hematite are believed to be primary sedimentary or diagenetic minerals, essentially unaltered in metamorphism (James, 1954 Huber, 1960 Garrels et al., 1973 Klein, 1973 Klein and Fink, 1976 Drever, 1974). 

Glauconite a green mineral, essentially a hydrous potassium iron silicate.

During the past two decades the significance of bacteria in aquatic ecosystems has undergone a reassessment. Once viewed solely as re-mineralizers , essential only for mineralization of dissolved and particulate detritus, aquatic bacteria are increasingly viewed as essential components in aquatic food webs. 

Sea lettuces which draw from the sea contain wealth of mineral elements (Table 5.4). Calcium, one of the most important minerals essential for human body, is accumulated in sea lettuces at a higher level compared with milk, brown rice, spinach, peanuts, and lentils (MacArtain et ah, 2007). Calcium contents in Ulva lactuca, Ulva reticulata, Ulva fasciata were 32.5, 147, and 0.47 mg/100 g edible portion, respectively. Moreover, potassium and sodium are known as electrolytes because their ability to dissociate into positively and negatively charged ions when dissolved in water. Potassium is the major cation of intracellular fluid. Together with sodium, it maintains normal water balance. In addition, potassium also promotes cellular growth and maintains normal blood pressure. Potential source of potassium is Ulva reticulata, which contains 1540 mg potassium per 100 g edible portion (Ratana-arpom and Chirapart, 2006). 

A total of 24 minerals (essentials and nonessentials) have been reported so far in hazelnut varieties, of which 13 essential mineral content are summarized in Table 12.2 by various studies [ 11,14,23,24,214]. In addition to the data in Table 12.2, mineral content of various hazelnut varieties has also been reported by several researchers [9,15,16,25-27,215]. In general, potassium is the most abundant mineral, followed by phosphorus, calcium, and/or magnesium. Several studies have indicated that mineral composition of hazelnut is affected by variety, geographical origin, harvest year, climate, composition of soU, irrigation, use of fertilizer, and method of cultivation [15,24,26,28]. 

Hazelnut, which contains lipid-lowering bioactives such as MUFA, PUFA, phytosterols, phytostanols, polyphenols, and sphingolipids [11,12,107,117,140,141,147,175,183,189,203-205], offers an opportunity as a potential hypercholesterolemic heart-healthy diet component In addition to these bioactives and minor components, there are a number of nonfat constituents (such as essential minerals, essential amino acids, antioxidant phenoUcs, soluble dietary fiber, and phytochemicals, among others) in hazelnut that may elicit additional cholesterol-lowering and cardioprotective effects [11,57,59,85,117,174,206]. 

Shale A rock formed by consolidation of clay, mud, or silt, having a laminated structure and composed of minerals essentially unaltered since deposition. 

Phytochemistry Fruits contain vitamins (C, Bj, B, B, PP, E, and A), organic acids (citric, malic, salicylic, tartaric, formic, and capronic), ellagic acid and its derivatives, sugars, pectins, minerals, essential oil, anthocyans, flavonoids, and tannins. Seeds contain fatty oils, sitosterin, tocopherols, neutral lipids, phospholipids, and free fatty adds. The main fatty acids of crude oil were 18 2 (54.5 %), 18 3 (29.1 %), 18 1 (12 %), and 16 0 (2.7 % Tolmachev 1976 Khalmatov et al. 1984 Kurochkin 1998 Oomah et al. 2000 Zafrilla et al. 2001). 

In small amounts, the fluoride ion (often consumed as NaF) prevents tooth decay. According to the American Dental Association, an adult female should consume 3.0 mg of fluorine per day. Calculate the amount of sodium fluoride (45.24% F) that a woman should consume to get the recommended amount of fluorine. 78. The iodide ion, usually consumed as potassium iodide, is a dietary mineral essential to good nutrition. In countries where potassium iodide is added to salt, iodine deficiency or goiter has been almost completely eliminated. The recommended daily allowance (RDA) for iodine is 150 /ig/day. How much potassium iodide (76.45% 1) should you consume to meet the RDA ... 

By breaking down biomass and mineralizing essential elements, especially nitrogen and phosphorus, aquatic microorganisms play a key role in nutrient cycling.
