A mixture of cis-decalin and CXB can simultaneously match optical index and density of PMMA. [1] Due to the moderate dielectric constant of CXB (ε = 7.9 [2]), PMMA acquires charges that can be screened by the addition of salt (e.g. tetrabutyl ammonium bromide), leading to a very good approximation of colloidal hard sphere.

This is a list of cis-regulatory RNAs. These are RNA motifs which regulate nucleic acid regions on the same molecule, as opposed to trans -acting motifs which regulate a distal molecule. Some of these RNAs are broadly distributed while others are single RNA families.
cis-1,2-Dihydrocatechol is the organic compound with the formula C 6 H 6 (OH) 2. Several isomers exist with this formula. It is a colorless solid melting near room temperature. The compound is classified as a 1,3-cyclohexadiene. It arises by the dihydroxylation of benzene catalyzed by toluene dioxygenase.
Enoyl-CoA-(∆) isomerase (EC 5.3.3.8, also known as dodecenoyl-CoA-(∆) isomerase, 3,2-trans-enoyl-CoA isomerase, ∆3(cis),∆2(trans)-enoyl-CoA isomerase, or acetylene-allene isomerase, [1] is an enzyme that catalyzes the conversion of cis- or trans-double bonds of coenzyme A (CoA) bound fatty acids at gamma-carbon (position 3) to trans double bonds at beta-carbon (position 2) as below:
trans-1,3-Disubstituted cyclohexanes are like cis-1,2- and cis-1,4- and can flip between the two equivalent axial/equatorial forms. [ 2 ] Cis -1,4-Di- tert -butylcyclohexane has an axial tert -butyl group in the chair conformation and conversion to the twist-boat conformation places both groups in more favorable equatorial positions.
In enzymology, a cis-2-enoyl-CoA reductase (NADPH) (EC 1.3.1.37) is an enzyme that catalyzes the chemical reaction. acyl-CoA + NADP + cis-2,3-dehydroacyl-CoA + NADPH + H +. Thus, the two substrates of this enzyme are acyl-CoA and NADP +, whereas its 3 products are cis-2,3-dehydroacyl-CoA, NADPH, and H +.
Thus, the two substrates of this enzyme are cis-3-phenylcyclohexa-3,5-diene-1,2-diol and NAD +, whereas its 3 products are biphenyl-2,3-diol, NADH, and H +. This enzyme belongs to the family of oxidoreductases , specifically those acting on the CH-CH group of donor with NAD+ or NADP+ as acceptor.
Thus, the two substrates of this enzyme are cis-1,2-dihydronaphthalene-1,2-diol and NAD +, whereas its 3 products are naphthalene-1,2-diol, NADH, and H +. This enzyme belongs to the family of oxidoreductases , specifically those acting on the CH-CH group of donor with NAD+ or NADP+ as acceptor.
