The lipids of three psychrophilic yeasts of the genus Candida, grown a t lo0, were compared with those of a mesophilic yeast (Candida lipoly'ica) grown a t 2S0 and a t 10'. All the yeasts examined had siinilar contents of total lipids and of phosphatides, and similar phosphatide and neutral lipid compositions. However, the total fatty acids of the psychrophiles and of the inesophile grown a t 10' had much higher proportions of linoleic acid and lower proportions of oleic acid than those of the mesophilic yeast grown a t 25'; the psychrophilic yeasts also contained linoleiiic acid, not detected in the mesophilic yeast. The fatty acid cornposition of the psychrophilic yeast remained fairly constant during its growth cycle, but that of the mesophilic yeast a t 10' showed marked changes in the proportions of oleic and linoleic acids in the early stages of growth; siinilar changes occurred in the mesophile grown a t 2S0, but a t much faster rates. (111 the basis of these observations and others it is concluded that in the early stages of growth of the mesophile a t 2S0 and lo0, oleic acid is converted rapidly to linoleic, which is then oxidatively metabolized during the later stages of active growth. 'I'he higher proportions of linoleic acid in the mesophile grown a t 10' could be accounted for by a slower rate of metabolism of linoleic acid during the later stages of growth a t the lower temperature. 1Manuscript received March 30, 1962.

“…22,23 These classical studies have been supplemented by semiclassical and quantum-mechanical calculations in areas where quantum effects can play an important role. 24,25 The focus at present is on more complex molecules, the redistribution of their internal energy, and the effect of this on reactivity. 26 The other pathway in molecular dynamics has been concerned with physical rather than chemical interactions and with the thermodynamics and dynamic properties of large numbers of particles, rather than detailed trajectories of a few particles.…”

A description of the origin of my interest in and the development of molecular dynamics simulations of biomolecules is presented with a historical overview, including the role of my interactions with Shneior Lifson and his group in Israel. Some early applications of the methodology by members of my group are summarized, followed by a description of examples of recent applications and some discussion of possible future directions.

“…The semiclassical propagation can describe the quantum-mechanical effects with acceptable accuracy for a variety of problems. Now the HK propagator and its variations have been applied to reactive scattering, 13 complex molecular systems, [14][15][16] surface scattering, 17 condensed phase, [18][19][20][21][22] and nonadiabatic systems [23][24][25][26] despite several undesirable features.…”

Phys. 135, 204503 (2011) Mo "ller operators in the formulation of reaction probabilities in terms of wave packet correlation functions allow us to define the wave packets in the interaction region rather than in the asymptotic region of the potential surface. We combine Mo "ller operators with the semiclassical propagator of Herman and Kluk. This does not involve further approximations and can be used with any initial value representation ͑IVR͒ semiclassical propagator. Time propagation in asymptotic regions of the potential due to Mo "ller operators reduces the oscillations of the propagator integrand and improves convergence of the results with respect to the number of trajectories. The effectiveness of Mo "ller operators for semiclassical reaction probability calculation is demonstrated for the collinear hydrogen exchange reaction. Full convergence is achieved and the number of classical trajectories is reduced by a factor of 10 compared to the calculation without Mo "ller operators.
