The crustacean cuticle—I. Studies on the composition of the cuticle

Comparative Biochemistry and Physiology A, Comparative Physiology, 1974
Abstract 1. 1. The content of calcium salts, protein and chitin has been measured in the cuticle of Astacus fluviatilis, Cancer pagurus, Carcinus maenas, Leander adspersus, Nephrops norvegicus and Penaeus duorarum. 2. 2. The solubility and the amino acid composition of the cuticles have been determined. 3. 3.

THE INSECT CUTICLE

Biological Reviews, 1948
SummaryThe cuticle consists of a relatively soft and colourless endocuticle, hardened and darkened in its outer part in some places to form a rigid exocuticle, and a complex epicuticle made up of several layers.The endocuticle consists of polyacetylglucosamine (chitin) intimately associated with a characteristic protein (arthropodin). Perhaps these are

Sclerotization of mosquito cuticle

Experientia, 1987
The mode of sclerotization of Aedes aegypti pupal and adult cuticle was examined by employing biochemical and radioactive techniques. During larval-pupal metamorphosis, tyrosine is converted to tanning precursors and is incorporated into aryl-amino adducts and beta-crosslinks. The major hydrolysis product of beta-crosslinks in pupal cases is identified

The Proteome of the Wool Cuticle

Journal of Proteome Research, 2010
The cuticle is responsible for important wool fiber characteristics such as handle and abrasion resistance, which impact on the fiber's performance in both interior and apparel textiles. The cuticle proteome, however, is not well understood due to the difficulty in isolating pure wool cuticle and its significant resistance to protein extraction, which ...

Structure of the Cuticle of Wool

Nature, 1946
THE flattened cells, forming the imbricated scaly sheath of the keratin fibres, wool and hair, appear comparatively structureless under the optical microscope ; using the electron microscope (R.C.A. Type EMU), however, we have been able to distinguish several component structures of the cuticle cells of wool both by their appearance and by their ...

Chemical composition of the nematode cuticle. Observations of the whole cuticle

Experimental Parasitology, 1956
Abstract 1. (1) The following sixteen amino acids have been detected in the hydrolysed cuticles of Ascaris lumbricoides, Toxocara mystax and Strongylus equinus: glycine, alanine, valine, leucine, threonine, cystine, cysteic acid, aspartic acid, glutamic acid, lysine, arginine, histidine, tyrosine, tryptophane, proline and hydroxy-proline. 2.

Cuticle itself as a central and dynamic player in shaping cuticle

Current Opinion in Insect Science, 2017
The wide variety of external morphologies has underlain the evolutionary success of insects. The insect exoskeleton, or cuticle, which covers the entire body and constitutes the external morphology, is extracellular matrix produced by the epidermis. How is cuticle shaped during development?

Permeability of Insect Cuticle

Nature, 1947
I HAVE chanced to make an observation, at present unexplained, which may throw light on the properties of insect cuticle.

Composition of cast larval cuticle of Schistocerca, puparial cuticles of Eristalis and Calliphora, and pupal cuticle of Cydia

Insect Biochemistry, 1975
Abstract A quantitative method of fractionation is described. Soluble and residual protein fractions together constitute at least 60 per cent of the integuments. A chitin fraction comprises about 20 per cent of the larval skin and about 25 to 35 per cent of the pupal coverings.
