What's the difference between lobster and lobsterback?

Lobster


Definition:

  • (n.) Any large macrurous crustacean used as food, esp. those of the genus Homarus; as the American lobster (H. Americanus), and the European lobster (H. vulgaris). The Norwegian lobster (Nephrops Norvegicus) is similar in form. All these have a pair of large unequal claws. The spiny lobsters of more southern waters, belonging to Palinurus, Panulirus, and allied genera, have no large claws. The fresh-water crayfishes are sometimes called lobsters.

Example Sentences:

  • (1) Quantitative measurements for 5-HT in lobster larvae were performed using high pressure liquid chromatography (HPLC) with dual electrochemical detection and for proctolin using radioimmunoassay.
  • (2) However, the 'essential' cysteine residue 165 is replaced by threonine, as it is in the L-lactate dehydrogenase of lobster.
  • (3) The responses of a population of 30 olfactory receptor cells from spiny lobsters to 8 behaviorally relevant complex types of stimuli at 0.005, 0.05 and 0.5 mM were analyzed using multidimensional scaling to evaluate their potential for coding quality and intensity.
  • (4) Using a spectrophotometric method, the kinetics of the crustacean muscle enzyme was compared to the acetylcholinesterase (AChE) on mammalian red blood cells and in the lobster ventral nerve cord.
  • (5) In crustacean nerve 12-14% of the phospholipids was in the form of alkyl ether phospholipids, which in the lobster were approximately half choline-containing and half ethanolamine-containing.
  • (6) Extracellular responses to complex biologically relevant stimuli were recorded from 30 primary olfactory cells from excised antennules of spiny lobsters.
  • (7) Analogues of arginine inhibit the exchange reaction of the lobster enzyme but enhance that of the Holothuria enzyme.
  • (8) Earlier studies identified purinergic chemoreceptors in the olfactory organ of the spiny lobster, Panulirus argus.
  • (9) The last in a line of fishermen, his 87-year-old grandfather is still catching lobsters.
  • (10) In view of the small molecular size and high lipid solubility of methyl mercury and the lipophilic properties of the chitin-protein exoskeleton of the lobster, it is likely that significant uptake directly from the water as well as storage of absorbed methyl mercury occurred in the tail region.
  • (11) The strongest extension response was produced at 2 Hz which falls within the normal range of swimmeret beating in intact lobsters.

  • (13) Of the other alkali-metal ions tested, only Rb+ activated phosphofructokinase from lobster abdominal muscle and rat heart muscle.
  • (14) This type of innervation was compared between a small and a large lobster where a two-fold difference in mean quantal content of synaptic transmission was found.
  • (15) The in vitro rates of incorporation of precursors into protein and RNA and the concentration of RNA were measured in tissues of intermolt and premolt lobsters acclimated to 5 degrees C and 20 degrees C. Midgut gland, abdominal muscle and gill of intermolt lobsters respond to temperature acclimation by a compensatory translation of the rate-temperature (R-T) curves with respect to the rates of incorporation of 3H-leucine and 3H-uridine into the acid-insoluble fraction.
  • (16) The role of histidyls in lobster arginine kinase (EC 2.7.3.3) has been studied by 1H-NMR spectroscopy of the enzyme and its complexes with substrates or their analogues and 31P-NMR spectroscopy of complexes with ADP.
  • (17) When the monocarboxymethylated enzyme was briefly treated with small amounts of iodine, iodination could be confined almost entirely to tyrosine-46 in the lobster enzyme; tyrosine-39 or tyrosine-42, or both, were also beginning to react.
  • (18) You’d be hard pushed to find half a dozen fresh oysters at this great price.” Frozen food giant Iceland sparked lobster wars last month with what it claimed was the cheapest cooked crustacean in Britain.
  • (19) Estrone, 17 beta-estradiol, or 17 alpha-estradiol was formed by central neural tissues of all species, with the exception of the opossum, hagfish, and lobster.
  • (20) Two metallothionein (low-molecular-weight, metal-binding proteins) preparations, MT-1 and MT-2, have been isolated from the digestive gland of American lobster (Homarus americanus) contaminated with Cd.
