hormone response element hre.

激素反应元件

a specific dna sequences capable of binding activated receptors. these elements regulate the gene expression. both steroids and peptide hormones exert their effects on transcription through hres but the initial reactions are different.

housekeeping gene.

管家基因

the genes that are expressed at a reasonably constant rate and not known to be subject to regulation.

induction.

诱导

synthesis of a particular protein in response to a signal stimulation in cellular metabolism. for example the synthesis of an enzyme can be induced by its substrate.

intron.

内含子

the mosaic nature of eukaryotic genes is discontinuous. the primary transcript of a gene contains the regions that are not present in the mrna. regions that are removed from the primary transcript are called introns.

isoelectric point.

等电点

the ph at which a molecule has a net zero charge.

isomerase.

异构酶

an enzyme that catalyzes an intramolecular rearrangement.

isozyme.

同工酶

distinct physical forms of an enzyme with the same catalytic activity. separation and identification of isozymes is of diagnostic value.

jaundice.

黄疸

when bilirubin in the blood reaches a certain concentration hyperbilirubinemia exists and bilirubin diffuses into the tissues which then became yellow. the condition is called jaundice.

ketogenic amino acid.

生酮氨基酸

an amino acid that yields only acetyl-coa. they can not yield pyruvate or tricarboxylic acid cycle intermediates.

ketone bodies.

酮体

acetoacetate hydroxybutyrate and acetone. at high rate of fatty acid oxidation the liver produces considerable quantities of acetoacetate and hydroxybutyrate. the former continually undergoes spontaneous decarboxylation to yield acetone. ketone bodies are metabolized in muscle and brain as an energy source.
