What's the difference between cerate and spermaceti?
Cerate
Definition:
(n.) An unctuous preparation for external application, of a consistence intermediate between that of an ointment and a plaster, so that it can be spread upon cloth without the use of heat, but does not melt when applied to the skin.
Example Sentences:

(2) Ceratitis capitata brain appears to have octopamine receptors as unique aminergic receptors coupled to adenylate cyclase.
(3) Drosophila melanogaster and Ceratitis capitata are insensitive to mannose and have excess of mannosephosphate isomerase over hexokinase.
(4) Alcohol dehydrogenase null mutants have been induced with X rays in Ceratitis capitata, for use in a genetic sexing system.
(5) Kinetics of incorporation of labelled fatty acids into the sn-positions points to a non-random distribution with respect to the major saturated and unsaturated fatty acids in triacylglycerols of larvae of Ceratitis capitata.
(6) Cuticle proteins of an insect pest, the Medfly Ceratitis capitata, were resolved in polyacrylamide gels and partially characterized.
(7) This phenomenon was particularly related to the subgroup melanogaster and in the dipteron Ceratitis capitata.
(8) Dual monitoring by UV absorption and fluorescence produced by cerate oxidation provides both sensitive and wide-ranging detection capability.
(9) DNA sequences that are enriched or specific to the genome of the male medfly, Ceratitis capitata, have been isolated using a differential hybridization approach.
(10) DNA fingerprinting has been used to detect genetic variation in the Mediterranean fruit fly, Ceratitis capitata.
(11) Serum protein-bound carbohydrates, L-fucose, sialic acid, D-galactose, and D-mannose, were measured as potential biologic markers in patients with breast cancer with the use of high-resolution anion exchange separation in combination with a sensitive cerate oxidimetric fluorescence detector system.
(12) During the intervening 10 million years, the Drosophila lineage lost the second intron and evolved distinct codon-preferences: the G + C use in the third coding positions is increased by 69% in Drosophila relative to Chymomyza or Ceratitis.
(13) The coding sequence has the same length as in Drosophila species and in Ceratitis capitata.
(14) The Mediterranean fruit fly, Ceratitis capitata (Wiedemann), the melon fly, Dacus cucurbitae Coquillett, and the oriental fruit fly, D. dorsalis Hendel, three Hawaiian tephritids of economic importance, were exposed to traps each containing one of 232 ethyl ether extracts of air-dried botanicals.
(15) The autosomal recessive allele v wing (v) in the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), produces flies that when reared at 30 degrees C have stubby wings.
(16) The nucleotide or amino acid distances support a phylogeny in which Ceratitis first branches off the common stem, then Chymomyza splits before the divergence of the two major Drosophila subgenera.
(17) A concerted effort is under way to analyze, at the genetic, biochemical, and molecular level, the Adh gene system in the medfly Ceratitis capitata, an important agricultural pest.
(18) Membrane preparations from immature stages of the fruit fly Ceratitis capitata catalyze the transfer of mannose from GDP-[14C]mannose into lipid-linked oligosaccharides.
(19) Electrophoretic study of haemolymphatic proteins in Ceratitis capitata has allowed to establish a proteic sexual dimorphism in this insect.
(20) The methylating activity of (methyl-14C)-S-adenosylmethionine by microsomes from different stages of development of the insect Ceratitis capitata was studied in a series of in vitro experiments.
Spermaceti
Definition:
(n.) A white waxy substance obtained from cavities in the head of the sperm whale, and used making candles, oilments, cosmetics, etc. It consists essentially of ethereal salts of palmitic acid with ethal and other hydrocarbon bases. The substance of spermaceti after the removal of certain impurities is sometimes called cetin.
Example Sentences:
(1) A repository dosage form was devised that consisted of an s.c. implant of pyridoxal phosphate suspended in a spermaceti and peanut oil mixture.
(2) The complex represents the most important factor in the morphogenesis and growth of the characteristic big forehead in Physeter, which contains the spermaceti organ unique within the odontocetes.
(3) In examining further, methadone hydrochloride suspensions were developed using spermaceti or eudragit retard-1 for particle coating.
(4) Nevertheless, these differences have to be taken as specializations related to the development of the far-advanced spermaceti organ.
(5) When I opened it, I found block after block of solid, pure, spermaceti wax , the solidified oil from the sperm whale’s head.
(6) So fine is spermaceti oil that Nasa used it in their space mission, as it does not freeze in outer space.
