Copper is primarily absorbed in the small intestine in humans, with the highest absorption rates occurring in the jejunum. Studies have shown that the jejunum, particularly the distal section, exhibits the highest copper absorption compared to other parts of the small intestine. This is crucial as copper is an essential trace element required for various enzymatic processes in the body, such as energy generation and neurotransmission. The absorption of copper in the small intestine is facilitated by specific transporters in enterocytes, allowing for the uptake of dietary copper into the body for metabolic functions. Overall, the small intestine, especially the jejunum, plays a vital role in the efficient absorption of copper from the diet in humans.How does the size of grains affect the plasticity of materials?

The size of grains significantly influences the plasticity of materials. Larger grain sizes promote twinning during plastic straining, enhancing the twinning induced plasticity (TWIP) effect and suppressing dislocation proliferation. In the semi-brittle regime, grain size controls rock strength and strain hardening behavior, impacting the long-term rheology of the crust. For Zn alloys, ultrafine-grained structures enable low-temperature superplasticity, with smaller grain sizes leading to improved elongation and deformation mechanisms involving dynamic recrystallization and grain boundary sliding. In OFHC copper, grain size affects yield stress, strain rate sensitivity, and thermal softening, with a developed constitutive model showing increased strain rate sensitivity and reduced thermal softening with larger grain sizes. A physically based model for grain boundary sliding accurately predicts flow stress for plastic deformation across a wide range of materials and grain sizes.What can inhibit copper absorbtion in humans?
