What Are the Essential Elements Needed for the Determination of Amino Acid Requirements in Humans

摘要: The aims of this introductory article are to survey and critically evaluate the concepts approaches that have been used assess amino acid adequacy hypothesize about possible future directions research. issue in question is extensive, consequently will be limited to: 1) definitions requirements; 2) available techniques 3) actual recommendations for healthy adults; 4) factors influencing 5) requirements acute chronic wasting diseases. Recommendations intakes adults were proposed by FAO/WHO expert committee 2001. They not yet published. major affecting stage development, reproductive state, environmental factors, digestibility dietary proteins, genotype individual, pathological conditions. Remarkably, there no conclusive data relative changes induced infection, injury, trauma, renal or liver failure. Future research using modern methods must thus receive a high priority. Wasting diseases associated with deficiencies imbalances particular acids causing specific requirements. Consequently, new approach has categorize as conditionally indispensable according their functional physiological properties. Kinetic measurements plasma might help estimate qualitative Measurement tissue intracellular free excesses another method Based on these tentative values during disease given article.
