This differentiation of configurational and conformational stereoisomers is not allways unambiguous, but generally conformational isomers may interconvert in each other through rotations about C-C single bonds only (this will not interconvert configurational isomers). (tu-darmstadt.de)

It is a form of isomers where molecules with the same molecules' properties create a bond in different orders to oppose stereoisomerism. (nftartranking.com)
Isomerism3
In stereochemistry, stereoisomerism, or spatial isomerism, is a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space. (wikipedia.org)

Molecules4
Recognition of the three dimensional shape of molecules and the resulting symmetry implications is fundamental to an understanding of organic chemistry, especially stereoisomerism. (msu.edu)
Below examples are given, in which chirality results from conformational effects, whereas chemical formulas at first sight suggest planar conformations of molecules (see 'Helical Chirality' below). (tu-darmstadt.de)

Compounds1
Our data suggest that LINGO-1 forms constitutive cis-dimers at the plasma membrane and that low MW compounds affecting the conformational state of these dimers can regulate LINGO-1 downstream signalling pathways. (nih.gov)
Identify1
A BRET-based assay allowed us to identify phenoxybenzamine as the first conformational modulator of LINGO-1 dimers. (nih.gov)
Double bond4
Stereoisomerism about double bonds arises because rotation about the double bond is restricted, keeping the substituents fixed relative to each other. (wikipedia.org)
The essential requirement for this stereoisomerism is that each carbon of the double bond must have two different substituent groups (one may be hydrogen). (msu.edu)
In the first example, the left-hand double bond carbon has two identical substituents ( A ) so stereoisomerism about the double bond is not possible (reversing substituents on the right-hand carbon gives the same configuration). (msu.edu)
In the next two examples, each double bond carbon atom has two different substituent groups and stereoisomerism exists, regardless of whether the two substituents on one carbon are the same as those on the other. (msu.edu)
