Molecular “Vitalism”
ate on very different principles. Even the simple signal-response of an allosteric enzyme is not machine-like Berkeley, California 94720 when examined in detail. Allosteric proteins have intrin-sically active and inactive conformations, which exist in some ratio in the absence of an external signal (Monod In the early nineteenth century, views on the nature of et al., 1965; Henry et al., 1997)....
متن کاملThe Nature of Moral Vitalism
Moral vitalism refers to a tendency to view good and evil as actual forces that can influence people and events. We introduce a scale designed to assess the belief in moral vitalism. High scorers on the scale endorse items such as “There are underlying forces of good and evil in this world.” After establishing the reliability and criterion validity of the scale (Studies 1, 2a, and 2b), we exami...
متن کاملOn the Vitality of Vitalism
MANY OF those who share an interest in the life sciences today, perhaps most, would agree with the claim that vitalism is obsolete. Some prominent biologists now use ‘vitalism’ as a derogatory label associated with lack of intellectual rigour, anti-scientific attitudes, and superstition (see, e.g., Dawkins, 1988). Other scientific commentators treat the term more seriously, but equally arrive a...
متن کاملAnimism, vitalism, and the Medical University of Montpellier
Bichat was one of the last medical theorists of any particular influence to insist uncompromisingly that physics and chemistry were separate sciences from physiology, making specious the application of their principles to the study of living processes. He saw the science of physiology as a unique discipline concerning itself with activities that have no counterpart in the sciences of the physic...
متن کاملEpimerization and stereochemistry of avoparcin.
The epimerization of avoparcin entities is discussed in some detail. The absolute stereochemistry of avoparcin is now known since the N-methyl terminal amino acid of the aglycone has been isolated and shown to exhibit negative optical rotation and hence has the R-configuration. The same amino acid has been isolated from an epimerized solution of avoparcin and found to have positive rotation and...
