What's the difference between bilin and biological?
Bilin
Definition:
(n.) A name applied to the amorphous or crystalline mass obtained from bile by the action of alcohol and ether. It is composed of a mixture of the sodium salts of the bile acids.
Example Sentences:
(1) These results indicate that an A-ring ethylidene-containing bilatriene is required for post-translational covalent attachment of bilin to apophytochrome and that apophytochrome may be the bilin C-S lyase which catalyzes bilin attachment.
(2) Some regions of the sequence are most similar to the retinol-binding protein, beta-lactoglobulin subgroup, while the disulphide bonding pattern is more akin to that seen in the porphyrin binding proteins insecticyanin and bilin-binding protein.

(5) The evidence from the NMR data for all bilin peptides examined includes the dipoledipole interactions of the 5-H with the 3-H, 3'-H, and a pyrrole methyl group (7-CH3); the corresponding interactions would not be possible in a D-ring-linked bilin.
(6) Analysis of bilin peptides obtained upon tryptic digestion of the adduct showed residues alpha-Cys-84 and beta-Cys-82 to be the sites of bilin addition.
(7) delta-Aminolevulinic acid is the universal precursor for all tetrapyrroles including hemes, chlorophylls, and bilins.
(8) 6301 C-phycocyanin and the phycoerythrobilin-containing peptide beta-2TP from Porphyridium cruentum B-phycoerythrin indicated a different single thioether mode of attachment, postulated to be through the D-ring of the tetrapyrrole, in contrast to the A-ring linkage established for the other singly linked bilins in these proteins (Bishop, J.E., Lagarias, J.C., Nagy, J. O., Schoenleber, R.W., Rapoport, H., Klotz, A.V., and Glazer, A.N.
(9) Phycocyanobilin is the immediate precursor of the protein-bound bilin.
(10) Chromophore-containing peptides were produced by trypsin treatment and purified in order to isolate the individual peptide-bound bilins free of overlapping absorption.
(11) Immunophenotyping, however, showed extensive overlap of myeloid and lymphoid markers, confirming the leukemia to be biphenotypic rather than true "bilineal."
(12) Putative bilin-contacting residues differing between the two phycoerythrins were identified which may determine bilin specificity.
(13) However, these results imply that the information loss due to bilineality is not necessarily very great.
(14) The light-absorbing chromophores of the phycobiliproteins are linear tetrapyrroles (bilins) very similar in structure to the mammalian bile pigments.
(15) These measurements show that 62-75% of the phytochrome apoprotein in the soluble protein extract was competent to assemble with bilins to form spectrally active holophytochrome.
(16) In contrast, six bilins were attached to strain WH8103 and WH8020 PE(II)s. Five of these were at positions homologous to bilin attachment sites in other phycoerythrins.
(17) However, comparison of the bilins of Cr-PE 566 from strain Bermani with those of Cr-PE 566 of strain CBD shows that the two proteins carry different bilins on the alpha subunit.
(18) Two groups of ASP alcoholic patients were compared: (1) 11 high familial (bilineal) alcoholics, and (2) 22 low familial (nonfamilial or unilineal) alcoholics.
(19) Comparison of the bilin portion of the NMR spectra of the alpha-1 MBV and beta-1 MBV peptides to the NMR spectra of PCB and mesobiliverdin confirms that the bilin of the two adduct peptides resembles mesobiliverdin in having an extra double bond in the C2-C3 position of ring A.
(20) These results show that the major bilin products arising from the reaction of PCB with apophycocyanin differ from the bilins present in C-phycocyanin.
Biological
Definition:
(a.) Of or relating to biology.
Example Sentences:
(1) Patients with papillary carcinoma with a good cell-mediated immune response occurred with much lower infiltration of the tumor boundary with lymphocyte whereas the follicular carcinoma less cell-mediated immunity was associated with dense lymphocytic infiltration, suggesting the biological relevance of lymphocytic infiltration may be different for the two histologic variants.
(2) Among a family of 8 children, 4 presented typical clinical and biological abnormalities related to mannosidosis.
(3) The HTCA is promising as a potential tool for studying the biology of tumors.
(4) Over the past decade the use of monoclonal antibodies has greatly advanced our knowledge of the biological properties and heterogeneity that exist within human tumours, and in particular in lung cancer.
(5) The lipid A moiety was shown to be responsible for this novel biological activity of the LPS molecule.
(6) Chromatography and immunoassays are the two principal techniques used in research and clinical laboratories for the measurement of drug concentrations in biological fluids.
(7) Biological magnification of insecticides and PCB's occurred in both lakes.
(8) In spite of important differences in size, chemical composition, polymer density, and configuration, biological macromolecules indeed manifest some of the essential physical-chemical properties of gels.
(9) No biologic investigation of the hemostatic impairment could be performed under the emergency conditions of this field study.
(10) It is the absorbed dose in joules per gram that is biologically significant and the data shows that the mean absorbed dose to death within either sex shows no significant difference with respect to age or weight, but that the difference between the sexes are significant, particularly among the aged ex-breeders.
(11) Although chronologic age may not be a good predictor of pregnancy outcome, adolescents remain a high-risk group due to factors which are more common among them such as biologic immaturity, inadequate prenatal care, poverty, minority status, and low prepregnancy weight, and because factors associated with an early adolescent pregnancy, such as low gynecologic age, may continue to influence the outcome of subsequent pregnancies.
(12) The analysis of blood lead concentration revealed an evident biological response to this environmental change: there was a decrease in blood lead level between 1977 and 1987, in both the countryside (control group) and, to a lesser extent, in the city.
(13) Combination of domain substitutions to generate the [Glu107,123]bFGF and [Arg19,Lys123,126]bFGF mutants did not show any additivity of the mutations on biological activity.
(14) Thus, introduction of arginine in position 5 with a hydrophobic amino acid in position 6 is compatible with high potency in several biological systems and results in compounds with lowered potency to release histamine compared to homologous peptides with tyrosine in position 5 and D-arginine in position 6.
(15) The crystal structure of the biological stain, "acridine orange," has been determined.
(16) Improvement of its particularly poor prognosis requires therefore early screening based on reliable biological markers.
(17) The availability of locus-specific probes should significantly expand the role of minisatellite markers in population biology.
(18) That’s important, because Ebola is the Isis of biological agents .
(19) Men older than 75 showed a slightly higher mortality during the first year, but there were seemingly no relationships of tumor-biological or clinical significance between age at diagnosis and long-term relative survival.
(20) Since the employment of microwave energy for defrosting biological tissues and for microwave-aided diagnosis in cryosurgery is very promising, the problem of ensuring the match between the contact antennas (applicators) and the frozen biological object has become a pressing one.
