The Journal of Physiology
This laevorotation reaches a maximum with the formation of a precipitate which is
equally distributed throughout the fluid. With the settling of the precipitate the
laevorotation gradually diminished and it was during this stage that we were
forced ...

The feeble laevorotation of the oils 3 to 6 is worthy of note. As the distillation was
carried out under our constant supervision, and special attention was paid to the
fact that no lavender was present among the spike blossoms, a slight ...

The American Perfumer and Essential Oil Review
From an examination of all these figures it appears that the dextrorotatory
samples would usually be adjudged better than samples which had much
laevorotation: for the presence of much stalk in the herb appears to be to some
extent the ...
Rhamnose, originally dextrorotatory, becomes laevorotatory on oxidation, and
the rotation is practically constant after 2 gram-atoms of oxygen have been added
. This laevorotation appears to be due to the presence of a laevorotatory keto-
acid ...

In the D-series of sugars having laevorotation, it is the p-anomer which has a
higher laevorotation. Thus fructose having a specific rotation of -20° will be a-D (-
) fructose and the other one with a specific rotation of -133° will be the P-anomer.

A physico-chemical approach to the denaturation of proteins
Probably as a consequence of the presence of two additional aspartic acid
residues in j8-lactoglobulin A, its laevorotation drops at pH 3-8, then decreases to
pH 4-1, and finally increases to pH 5-0; the curve afterwards parallels that of ...

The laevorotation of /?A and /SB decreases slightly on addition of the
amphiphiles up to a molar ratio of 2//Mactoglobulin, the more the longer the
carbon chain. A marked, up to about twofold, laevorotation increase is observed
at ratios above ...
But the laevorotation of fructose is much more in magnitude than the
dextrorotation of glucose, with the result that solution of sucrose exhibits
laevorotation. As inversion in optical rotation takes place, it is called invert sugar.
Sucrose does not ...

The Amphimedon sponge also contains several manzamine related alkaloids
with both dextrorotation and laevorotation. The minor enantiomer of
keramaphidin B ((−)(662)) is considered to possess the same configuration as
most of the ...

The resultant product of hydrolysis shows laevorotation. This change from
dextrorotation to laevorotation is called inversion. Therefore, sucrose is called
invert sugar. The net result is laevorotatory resulting in change of rotation from
positive ...
