The Nutritional Significance of Some Mineral Elements Occurring as Traces in the Animal Body *
Nearly twenty years ago, in one of their classic papers on the relation of growth to the chemical constituents of the diet, Osborne and Mendel7" wrote: "The animal cells need for their activities not only energy, but also suitable constructive materials to replace the wear-and-tear therein. Furthermore the cells are concerned in the elaboration of a great diversity of complex and little underst...
متن کاملThe mineral elements in homoeostasis and morphogenesis.
It is unusual to have a preface to a named lecture, but then it is an unusually great compliment to be invited by this Society to give a second lecture named after a distinguished biochemist. The first, the Keilin lecture, I gave on my version of how electronic events in bioenergetic chains, one of Keilin's great interests [ I ] , were linked through energy transduction to proton gradients and ...
متن کاملPlantain Ash Enhances Dietary Mineral Elements Absorption in Pullets
Generally, only a fraction of the mineral ingested by an animal is effectively absorbed, while most are bound to other components such as fibre and then excreted. In this study, faecal mineral composition differentials were used as indicators of mineral uptake by pullets supplemented varying levels of plantain ash in their daily rations for nine weeks. Plantain stalk and root base samples were ...
متن کاملMineral elements in milk and dairy products
On average, mineral elements account for 4 % of total body mass and part of every tissue, liquid, cell and organ in human body. There is a sufficient evidence that minerals, both independently or in proper balance with other minerals, have structural, biochemical and nutritional functions that are very important for overall human health, both mental and physical (Vahčić et al., 2010). Furthermo...
متن کاملCrystals: animal, vegetable or mineral?
The morphologies of biological materials, from body shapes to membranes within cells, are typically curvaceous and flexible, in contrast to the angular, facetted shapes of inorganic matter. An alternative dichotomy has it that biomolecules typically assemble into aperiodic structures in vivo, in contrast to inorganic crystals. This paper explores the evolution of our understanding of structures...
