mucoprotein

 [mu″ko-pro´tēn]
a compound present in all connective and supporting tissues, containing, as prosthetic groups (non–amino acid components), mucopolysaccharides; soluble in water and relatively resistant to denaturation.
Tamm-Horsfall mucoprotein a substance produced by cells of the ascending limb of the loop of Henle; it is a normal constituent of urine and is the major protein constituent of urinary casts.

mu·co·pro·tein

(myū-kō-prō'tēn),
General term for a protein-polysaccharide complex, usually implying that the protein component is the major part of the complex, in contradistinction to mucopolysaccharide; mucoproteins include the α1- and α2-globulins of serum (and others). Sometimes called glycoproteins, although this term usually refers to those mucoproteins containing less than 4% carbohydrate.

mucoprotein

/mu·co·pro·tein/ (-pro´tēn) a covalently linked conjugate of protein and polysaccharide, the latter containing many hexosamine residues and constituting 4 to 30 per cent of the weight of the compound; they occur mainly in mucus secretions.

mucoprotein

(myo͞o′kō-prō′tēn′, -prō′tē-ĭn)
n.
Any of a group of organic compounds, such as the mucins, that consist of a complex of proteins and glycosaminoglycans and are found in body tissues and fluids.

mucoprotein

[myo̅o̅′kōprō′tēn, -tē·in]
Etymology: L, mucus + Gk, proteios, first rank
a compound, present in all connective and supporting tissue, that contains polysaccharides combined with protein. It is relatively resistant to denaturation.

mu·co·pro·tein

(myū'kō-prō'tēn)
General term for a protein-polysaccharide complex, usually implying that the protein component is the major part of the complex. Mucoproteins include the α1- and α2-globulins of serum.

mucoprotein

a complex of protein and polysaccharide.

mucoprotein

a compound present in all connective and supporting tissues, containing, as prosthetic groups, mucopolysaccharides; soluble in water and relatively resistant to denaturation. An important component of many uroliths.

Tamm-Horsfall mucoprotein
locally secreted in Henle's loops, the distal tubules, and the collecting ducts of the kidney; the principal constituent of hyaline casts.

Frogs produce a gelatinous jelly coat around their eggs that contains a variety of sulfur-containing mucoproteins and mucopolysaccharides that provide important structural barriers around the embryo essential for fertilization and hatching but are not believed to be nutritive (Duellman and Trueb 1986).
The secretion of the hypobranchial gland contains, besides fucose-rich mucopolysaccharides (fucomucins), mucoproteins, plasma proteins, enzymes, bit-active substances and also small amounts of pigment precursors.
Amino acids in the outflow at the terminal ileum contain AA from dietary origin as well as various endogenous proteins such as digestive secretions (saliva, bile, gastric, and pancreatic secretions as well as intestinal secretion), mucoproteins, sloughed intestinal epithelial cells, serum albumin, and amide (Moughan and Schutter, 1991; Ravindran and Bryden, 1999).
This action results in the breakdown of mucoproteins in the respiratory system, as it clears thick mucus up so that it can be more easily transported up and out of the body.
