Previous investigations of the biosynthesis of sterols by the
arterial wall have shown that the intact aorta is capable of low level
incorporation of labeled precursor into a sterol digitonide. The biosynthesis
of sterols and related lipids by a cell-free preparation of
bovine aorta was investigated in the present study....
The question of why carboxylic acids and phenols are stronger
acids than alcohols has been investigated experimentally and theoretically.
The experimental approach involves comparison of gas-phase
acidities and core-ionization energies. The theoretical treatment uses
calculated point potentials and acidities.
The ease of proton removal is related to two factors known...
Lamellar x-ray diffraction was studied from thin films of L-α-1,2-dipalmitoyl lecithin (DPL) and a 1:1 mixture (BrDPL) of L-α-l-palmitoyl-2-(9- bromopaimitoyl) lecithin and its 10-bromo analog. The specimens had high lamellar order, with an upper bound on the mosaicity of 6 mrad (0.4°) for DPL and BrDPL. With various water contents,...
An
investigation was
made
into certain
aspects
of
protein
synthesis
at
different
developmental stages
of the
flesh fly
Sarcophaga
bullata.
This
included
measurements
of the
incorporation of
labeled
amino
acids into
protein
by intact cells
from
a
single
organ, the
larval
fat
body,
and
a
study
of
