| Consequently, there may be a layer of fluid water around the chromophore that rearranges upon excitation. |
|
| In the second basic photocycle step, the chromophore is protonated and structural changes take place in the protein. |
|
| Visual pigments are composed of a light-absorbing chromophore that is bound to the protein opsin. |
|
| Apparently the monocyclic geometry leads to stronger interactions between peptide and chromophore extending also to longer times. |
|
| The amounts of chromophore were equalized among samples, absorption spectra for the native proteins were collected. |
|
| This implies that chromophore protonation precedes the exposure of hydrophobic surface. |
|
| The effect of the protein is modeled as an external field acting on the unperturbed eigenstates of the chromophore. |
|
| One of the major practical applications of chromophore chemistry is in the manufacture of synthetic dyes, or dyestuffs, for textiles. |
|
| The covalent linkage of the chromophore by copolymerization with MMA does not significantly alter its photophysics. |
|
| A protein-bound polyene chromophore is not the same as a polyene trapped within the cavity of an amorphous solid. |
|
| As the chromophore is a polyene, there are several double bonds capable of isomerization. |
|
| The bond selectivity and unidirectionality of the isomerization in bR are in striking contrast with those of the isolated chromophore. |
|
| Moreover, this spectrum is strikingly similar to the terminal spectrum measured after photoionization of the isolated PYP chromophore in solution. |
|
| We trace which amino acids contact the chromophore of rhodopsin. |
|
| Good examples are the cleaning of motorcar parts, car bodies and fenders before the final chromophore lacquering process. |
|
| This prevents the chromophore from migrating within the polymer while simultaneously improving the efficiency of energy transfer to the chromophore. |
|
| Examples of dyes, each containing a different chromophore, include azobenzene, xanthene, and triphenylmethane. |
|
| The opsin molecules themselves each consist of seven helices that cross the disk membrane and surround the chromophore. |
|
| In tissue, hemoglobin, an important tissue chromophore, varies in concentration and hence absorption as a direct result of blood flow. |
|
| Organic Eusolex® products from Merck are synthetic UV filters and comprise chromophore systems that absorb UV radiation. |
|
|
|
| The positive charge of the chromophore is localized primarily in the imine region of the chromophore and is stabilized by two nearby aspartic acid residues. |
|
| Lasers with wavelengths of 600-1100 nm penetrate deeply and are absorbed by eumelanin in the hair shaft and follicle, which is thought to be the target chromophore. |
|
| The unique properties of this chromophore provide a powerful tool to learn about these biopolymers without introducing the perturbation of an external probe. |
|
| While researchers have discovered all colored compounds do indeed contain one or more chromophores, not all chromophore containing compounds are colored. |
|
| This single mutation, modifying the nature of the aromatic nuclei which contribute to the stabilisation of the chromophore group, induces a change of the coloration of the fluorescence. |
|
| Alizarin contains the anthraquinone chromophore. |
|
| Reactive dyes utilize a chromophore attached to a substituent that is capable of directly reacting with the fiber substrate. |
|
| Phototransduction involves a conformational change in the chromophore and activation of an opsin. |
|
| The photopigments that absorb light all have a similar structure, which consists of a protein called an opsin and a small attached molecule known as the chromophore. |
|
| They combine two or more chromophore groups in each dye molecule in order to obtain high optical density using the same concentration of dyes as in the old ranges. |
|
| When the pigment molecule absorbs a photon, the chromophore isomerises from 11-cis to all-trans form. |
|
| A bathochromic shift of 14 nm occurred with sodium hydroxide, giving a peak maximum at 546 nm for the red chromophore. |
|
| In most invertebrate photoreceptors the chromophore does not detach from opsin but is regenerated in situ, usually by the absorption of a photon with a wavelength different from the stimulating wavelength. |
|
| The AcrySof Natural IOL was manufactured with the same material as the AcrySof single-piece IOL, but with an additional covalently bound yellow polymerisable chromophore. |
|
| In the last 20 years, HPLC has also been used, but it lacks the sensitivity of GC, because the trichothecenes generally lack a strong enough chromophore. |
|
| The chromophore group is an anthraquinone, methine, or azo compound. |
|
| Natural bacterial phytochrome photoreceptors utilize low molecular weight biliverdin as a chromophore and provide many advantages over other chromophore binding proteins. |
