Acid zeta function and ajoint acid zeta function [PDF]

open access: yesarXiv, 2010
In this paper we set up the theory of acid zeta function and ajoint acid zeta function, based on the theory, we point out a reason to doubt the truth of the Riemann hypothesis and also as a consequence, we give out some new RH equivalences.

Is Amino-Acid Homochirality Due To Asymmetric Photolysis In Space? [PDF]

open access: yesarXiv, 1999
Amino acids occurring in proteins are, with rare exceptions, exclusively of the L-configuration. Among the many scenarios put forward to explain the origin of this chiral homogeneity (i.e., homochirality), one involves the asymmetric photolysis of amino acids present in space, triggered by circularly polarized UV radiation.

The accumulation of orotic acid by a pyrimidineless mutant of Neurospora [PDF]

open access: yes, 1948
The discovery of orotic acid (1,2-carboxyuracil) in cow's milk by Biscaro and Belloni (1), followed by its identification and synthesis (2-4), led to a number of speculations as to its biological origin and significance (,3,5,6).

The contribution of extracellular RNA and its derived biomaterials in disease management

open access: yesBMEMat, EarlyView.
The implications of exRNA's biological function and the structural uniqueness of RNA help establish a close connection between RNA, material, and modern medicine. Abstract The RNA found in the circular system is known as extracellular RNA (exRNA). This kind of RNA has been found to play a biological role similar to that of a messenger. They can be used

Are Strong Bronsted Acids Necessarily Strong Lewis Acids? [PDF]

open access: yesarXiv, 2006
The Broensted and Lowry acid base theory is based on the capacity of proton donation or acceptance (in the presence or absence of a solvent) whereas the Lewis acid base theory is based on the propensity of electron pair acceptance or donation. We explore through DFT calculation the obvious question whether these two theories are in conformity with each
