Vitamin K functions as a coenzyme during the synthesis of the biologically active form of a number of proteins involved in blood coagulation and bone metabolism. Because of the lack of data to estimate an average …

Extraction of molybdenum [28], [29] with amines and organophosphorous compounds is possible in low pH (normally 1–2). Fe, Co, Ni and Al are not extracted. Fe, Co, Ni and Al are not extracted. In pH below 2 MoO 2 2+ -type species predominate, whereas neutral or anionic species are dominant above this pH [30] .

Manganese is involved in the formation of bone and in amino acid, lipid, and carbohydrate metabolism. There were insufficient data to set an Estimated Average Requirement (EAR) for manganese. An Adequate Intake (AI) was set based on median intakes reported from the Food and Drug Administration Total Diet Study. The AI for adult men and women is …
