Asymmetry is the absence of, or a violation of, symmetry (the property of an object being invariant to a transformation, such as reflection). [1] Symmetry is an important property of both physical and abstract systems and it may be displayed in precise terms or in more aesthetic terms. [2]
So can those ending in -ch / -tch (e.g. "the French", "the Dutch") provided they are pronounced with a 'ch' sound (e.g. the adjective Czech does not qualify). Many place-name adjectives and many demonyms are also used for various other things, sometimes with and sometimes without one or more additional words.
Fish: Dorsal view of right-bending (left) and left-bending (right) jaw morphs [4]. Many flatfish, such as flounders, have eyes placed asymmetrically in the adult fish.The fish has the usual symmetrical body structure when it is young, but as it matures and moves to living close to the sea bed, the fish lies on its side, and the head twists so that both eyes are on the top.
Ethers can again be classified into two varieties: if the organyl groups are the same on both sides of the oxygen atom, then it is a simple or symmetrical ether, whereas if they are different, the ethers are called mixed or unsymmetrical ethers. [1]
Such adjective phrases can be integrated into the clause (e.g., Love dies young) or detached from the clause as a supplement (e.g., Happy to see her, I wept). Adjective phrases functioning as predicative adjuncts are typically interpreted with the subject of the main clause being the predicand of the adjunct (i.e., "I was happy to see her"). [11]
Unsymmetrical disulfides (also called heterodisulfides or mixed disulfides) are compounds of the formula RSSR'. Unsymmetrical disulfide are less common in organic chemistry, but many disulfides in nature are unsymmetrical.
A term's definition may require additional properties that are not listed in this table. In mathematics , an asymmetric relation is a binary relation R {\displaystyle R} on a set X {\displaystyle X} where for all a , b ∈ X , {\displaystyle a,b\in X,} if a {\displaystyle a} is related to b {\displaystyle b} then b {\displaystyle b} is not ...
Enantioselective synthesis, also called asymmetric synthesis, [1] is a form of chemical synthesis.It is defined by IUPAC as "a chemical reaction (or reaction sequence) in which one or more new elements of chirality are formed in a substrate molecule and which produces the stereoisomeric (enantiomeric or diastereomeric) products in unequal amounts."
