What's the difference between bilin and metabolic?
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.

(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.
Metabolic
Definition:
(a.) Of or pertaining to metamorphosis; pertaining to, or involving, change.
(a.) Of or pertaining to metabolism; as, metabolic activity; metabolic force.
Example Sentences:
(1) In studies of calcium metabolism in 13 unselected patients with untreated sarcoidosis all were normocalcaemic but five had hypercalcuria.
(2) The high amino acid levels in the cells suggest that these cells act as inter-organ transporters and reservoirs of amino acids, they have a different role in their handling and metabolism from those of mammals.
(3) Theophylline kinetics, as an in vivo probe for the potentially toxic cytochrome P-450I pathway of drug metabolism, were studied in 11 healthy volunteers and 11 patients with calcific chronic pancreatitis at Madras, South India.
(4) These results demonstrate that increased availability of galactose, a high-affinity substrate for the enzyme, leads to increased aldose reductase messenger RNA, which suggests a role for aldose reductase in sugar metabolism in the lens.
(5) The ability of azelastine to influence antigen-induced contractile responses (Schultz-Dale phenomenon) in isolated tracheal segments of the guinea-pig was investigated and compared with selected antiallergic drugs and inhibitors of arachidonic acid metabolism.
(6) These studies show that metabolic activation is necessary for the expression of the mutagenic activity of aflatoxins B1 and G1 in N. crassa.
(7) A progressively more precise approach to identifying affected individuals involves measuring body weight and height, then energy intake (or expenditure) and finally the basal metabolic rate (BMR).
(8) The penetration of (22)Na was not prevented by the presence of metabolic inhibitors or by 500 mm NaCl in the suspending medium.
(9) The data suggest that major differences may exist between ruminants and non-ruminants in the response of liver metabolism both to lactation per se and to the effects of growth hormone and insulin.
(10) This new observation offers good possibilities to study the metabolism of tryptophan at the cellular level.
(11) Also we found that the lipid deposition in the glomeruli of patients with Alagille syndrome is related to an abnormal lipid metabolism, which is the consequence of severe cholestasis.
(12) The obvious need for highly effective contraception in women with existing disorders of glucose metabolism has led to a search for oral contraceptive (OC) regimens for such women that are efficient but without unacceptable metabolic side effects.
(13) Angiopathic and traumatic influences conditioned by metabolism, apart from local peculiarities are taken into consideration.
(14) These results could be explained by altered tissue blood flow and a decreased metabolic capacity of the liver in obese subjects.
(15) MAF-G activity was inhibited by mitomycin C and colchicine, which inhibit DNA synthesis and mitosis, respectively, but not by 2-deoxy-D-glucose, an inhibitor of glucose metabolism.
(16) The measurement of the intestinal metabolism of the nitrogen moiety of glutamic acid has been investigated by oral ingestion of l-[15N]glutamic acid and sampling of arterialized blood.
(17) No significant fatty acid binding by proteins was detected in S. cerevisiae, even when grown on a fatty acid-rich medium, thus indicating that such proteins are not essential to fatty acid metabolism.
(18) These two types of transfer functions are appropriate to explain the transition to anaerobic metabolism (anaerobic threshold), with a hyperbolic transfer characteristic representing a graded transition; and a sigmoid transfer characteristic representing an abrupt transition.
(19) The sexual dimorphism in hepatic drug metabolism found in Crl:CD-1 mice is due to the normally repressive effects of testicular androgens on the activities of hepatic monooxygenases.
(20) In contrast, HEL antigen requires metabolically active cells for both of these processes.
