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:

  • (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.
