(Shak) 3. That which terminates a period of time; hence, the period itself; the full time or extent. "The dateless limit of thy dear exile." (Shak) "The limit of your lives is out." (Shak) 4. A restriction; a check; a curb; a hindrance. "I prithee, give no limits to my tongue." (Shak) 5. <logic> A determining feature; a distinguishing characteristic a differentia. 6. <mathematics> A determinate quantity, to which a variable one continually approaches, and may differ from it by less than any given difference, but to which, under the law of variation, the variable can never become exactly equivalent. Elastic limit. See Elastic. Prison limits, a definite, extent of space in or around a prison, within which a prisoner has liberty to go and come. Synonym: Boundary, border, edge, termination, restriction, bound, confine. Origin: From L. Limes, limitis: cf. F.limite; -or from E. Limit, v. See Limit.

| limit dextrin | The polysaccharide fragments remaining at the end (limit) of exhaustive hydrolysis of amylopectin or glycogen by alpha-1,4-glucan maltohydrolase, which cannot hydrolyze the alpha-1,6 bonds at branch points; accumulates in individuals with type III glycogen storage disease. Synonym: dextrin limit. (05 Mar 2000) |
| limit dextrinase | <enzyme> An enzyme with action similar to that of isoamylase; it cleaves 1,6-alpha-glucosidic linkages in pullalan, amylopectin, and glycogen, and in alpha-and beta-amylase limit-dextrins of amylopectin and glycogen. Compare: isoamylase. Synonym: limit dextrinase, pullulanase, R enzyme. (05 Mar 2000) |
| limit dextrinosis | Glycogenosis due to amylo-1,6-glucosidase deficiency, resulting in accumulation of abnormal glycogen with short outer chains in liver and muscle. Synonym: Cori's disease, debranching deficiency limit dextrinosis, limit dextrinosis, Forbes' disease. (05 Mar 2000) |
| limit of resolution | 1. <optics> The resolution of an optical system defines the closest proximity of two objects that can be seen as two distinct regions of the image. This limit depends upon the Numerical Aperture of the optical system, the contrast step between objects and background and the shape of the objects. The often quoted Airy limit applies only to self luminous discs. 2. <genetics> The smallest map distance measurable by an experiment involving a certain number of classified recombinant progency.
