What's the difference between lactamide and metameric?
Lactamide
Definition:
(n.) An acid amide derived from lactic acid, and obtained as a white crystalline substance having a neutral reaction. It is metameric with alanine.
Example Sentences:

(12) Since hydroxyethyl lactamide passed the severe "eolid nudibranch test" and has been found nonirritating for the very sensitive rhinophorial structures, and furthermore since it has been used by the pharmaceutical industry as a vehicle in antibiotic preparations, it appears to be an ideal universal dye solvent for general use in vital staining.
(13) Hydroxyethyl lactamide, an odorless liquid and dye solvent was found ideal since it permits immediate attainment of saturated solutions of dyes in sea water.
(14) Up to 50% glycerol, 10% hydroxyethyl lactamide (HELA), 10% oleyl alcohol, 10% Solketal, 10% glycofurol, 100% tetrahydrofurfuryl alcohol (THFA) and 10% urea induced no discernible change in the histological appearance of the skin whereas 100% dimethyl sulphoxide (DMSO), 100% dimethyl formamide (DMF), 100% N-methyl-2-pyrrolidone, 10% Azone, 10% oleic acid, 10% methyl laurate, 10% benzyl alcohol and 10% glycerol formal caused severe skin irritation.
(15) It was found that the beta-lactamides were active against Proteus, ceporin being the most effective antibiotic.
Metameric
Definition:
(a.) Having the same elements united in the same proportion by weight, and with the same molecular weight, but possessing a different structure and different properties; as, methyl ether and ethyl alcohol are metameric compounds. See Isomeric.
(a.) Of or pertaining to a metamere or its formation; as, metameric segmentation.
Example Sentences:
(1) This is especially evident on the ventral surface of the metamerically arranged axial muscles.
(2) The sloppy paired locus is involved in the establishment of the metameric body plan of the Drosophila embryo.
(3) In Haemopis embryos labeling of both nerve fibers and cell bodies with the antibody appears as expected for a metameric animal in a rostrocaudal temporal gradient from about day 5-6.
(4) These six metameres also are responsible for the existence of the pronephros.
(5) In each metamere, the area of cell migration takes place near the caudal border of the somite and, from one somite to the other, the number of migrating cells increases in a cephalo-caudal direction.
(6) The differences in levels between males and females and between anatomical regions during imaginal life suggest, in this species of cockroach, the physiological importance of the metameric organization in metabolic pathways or functional aspects of biogenic amines.
(7) Prior to dorsal closure, expression of the Drosophila gene is observed in non-neuronal tissues, especially in the mesectoderm and presumptive epidermis, both in a metameric pattern.
(8) Moreover, such a causative role of cell lineage is suggested by cases where homologous cell types characteristic of a symmetrical and longitudinally metameric body plan arise via homologous cell lineages.
(9) The case is characterized by successful counteracting the main clinical manifestations of Raynaud's phenomenon by the local metameric application of cerebrolysin (neuromeric, scleromeric puncturing) employed by the authors for the first time for the disease treatment.
(10) In mild contusion of the first-second segments the leading clinical symptoms in the acute period were pareses of the arms and paralyses of hands with retained reflexes and insignificant impairments of sensitivity in fingers, i.e., the level of clinical manifestations did not correspond with the conventional segmento-metameric innervation.
(11) A second group of patients had SAs that remained unchanged despite AVM changes (six of seven of these were in patients with metameric angiomatosis).
(12) The larval development of P. porosa is characterized by its passing in the cavity of the external cyst, by the complete separation of anlages of the body of the larva and cercomere at the metamere stage and by the intensive growth of the cercomere after the invagination of the larva.
(13) Life forms of plants are divided into thirteen types corresponding to the nature of their basic metameres.
(14) The invagination process of the metamere is described.
(15) This metameric migration pattern is thought to be caused by molecular differences between the rostral and caudal portions of the somite.
(16) Identification of specific neuronal populations and their projections in the developing hindbrain reveals a segmental organization in which pairs of metameric epithelial units cooperate to generate the repeating sequence of cranial branchiomotor nerves.
(17) In all three organisms, the pattern of engrailed expression at the segmented germ band stage is similar, and the parasegments are the first metameres to form.
