RenalTubularTransportof AminoAcids
Cushny in 1917 first remarked on the extensive amino acid reabsorption which occurs in the nephron. Although many workers since then have studied the nature and localization of the reabsorptive mechanism, progress has been slow because of the technical difficulties of micropuncture work. The bulk of filtered amino nitrogen is reabsorbed in the proximal tubule although the possibility of there b...
متن کاملOn the Phosphotungstates of Certain Aminoacids
In a communication to the Chemical Society ~ one of us reported on the property of aminoacids to form insoluble phosphotungstates. In a later publication 2 the writers showed the degree of precipitability of aminoacids by means of phosphottmgstic acid, and stated that a separation of aminoacids may be accomplished by means of this reagent. The at tempt was made to apply the method to the study ...

متن کاملA natural mechanism for l-homochiralization of prebiotic aminoacids
We propose a mechanism that explains in a simple and natural form the l-homochiralization of prebiotic aminoacids in a volume of water where a geothermal gradient exists. This model demands the following three assumptions: 1The process takes place in volume of water where there is a vertical thermal gradient (Fig.1). This situation is common even nowadays. For example, the subglacial lakeVostok...
متن کاملCyclic Variation of Free Aminoacids of Human. Endometrium in Relation to Dysfunctional Uterine Bleeding
The endometrium is one of the most dynamic structures in the human body characterised hy a complete life cycle within a short span of time. Although there can be no doubt about the role of estrogen in promoting endometrial growth and progesterone in influencing the differentiation, yet little is known of the mechanisms by which such changes are accomplished. Behind the constantly changing struc...
