Asymmetrical
Definition:
(a.) Incommensurable.
(a.) Not symmetrical; wanting proportion; esp., not bilaterally symmetrical.

(19) The analysis of these profiles showed that the reaction center protein incorporates into the phosphatidylcholine membrane with unique sidedness and that the profile of the reaction center protein itself is asymmetric and spans the membrane.
(20) The calorimetric data can be simply explained in terms of an asymmetric distribution of the major ROS disk membrane phospholipids (G.P.
Dissymmetrical
Definition:
(a.) Not having symmetry; asymmetrical; unsymmetrical.
Example Sentences:
(1) A strong negative band existing only in helical tropomyosin at pH's where the tyrosines are uncharged appears to be due to interaction of tyrosines with the helical backbone, whereas the appearance of a strong positive CD band at 250 nm at high pH (approximately11) seems to be ascribable to interaction between the charged phenolic groups and the dissymmetric backbone alpha-carbon atom.
(2) From the structural analysis of these free sialooligosaccharides, the following structures are proposed: (sequence; see text) Occurrence of such a symmetrically or dissymmetrically branched form of the biantennary nonreducing periphery as revealed here is novel.
(3) In concert, however, they reproduce all the main experimental features, if the strain is extensive (approximately 29 residues) and somewhat dissymmetric.
(4) One overwhelming characteristic of the ribosome is its apparent complexity, which is reflected both in the diversity of ribosomal components and in their dissymmetric arrangement.
(5) spectra of natural and (1-13C)-substituted dissymmetric alditols has permitted the unequivocal assignments of their hydroxymethyl proton and carbon signals and the measurement of several 13C-1H and 13C-13C spin-coupling constants.
(6) The origin of the homogeneity has been variously ascribed to a universal dissymmetric force, from Pasteur, or to a chance choice of the initial enantiomer perpetuated by the stereoselection of diastereomer production with recycling, from Fischer's "key and lock" hypothesis.
(7) They differ from it in the two processes of transmission of the infection, which are treated dissymmetrically.

(9) As a corollary it is inferred that the biphasic CD profile arises from excitonic coupling of these sulfur-centered transition dipole moments dissymmetrically oriented within the Cd(II)-thiolate clusters.
(10) It seems that xenobiotics need to be dissymmetric for chiral recognition by biological systems.
(11) The ability of dissymmetrical invariant turns during cytotomy, shown earlier when studying the whole embryos, is, thus, inherent to each blastomere irrespective of the neighbour ones but is supressed during the normal development after the III division mechanically due to the dense cellular packing projected by the orientation of spindles.
