(n.) A proteid substance present in both the animal and the vegetable kingdom. In the animal kingdom it is chiefly found in milk, and constitutes the main part of the curd separated by rennet; in the vegetable kingdom it is found more or less abundantly in the seeds of leguminous plants. Its reactions resemble those of alkali albumin.

(11) The regulatory region of the casein gene contains two different TATA signals flanking the duplication site in the promoter region.
(12) A mixture of amino acids simulating the amino acid pattern of casein was used with the same efficiency as casein.
(13) However, telolysosomes did increase temporarily at the onset of lactation and casein micelles were identified within secondary lysosomes throughout the lactation stage.
(14) Similar concentrations also increased directional movement of polymorphonuclear leukocytes to both endotoxin-activated serum and hydrolyzed casein.
(15) Some deviation was noticed in the weights of kidneys and adrenals of the chlorogec acid-free casein diet.
(16) Lower peptides and amino acids in hydrolyzates of casein obtained with protosubtilin were determined using high pressure liquid chromatography (HPLC).
(17) The loss of enzymatic activity towards casein and N-acetyl-L-tyrosine ethyl ester closely correlates with the destruction of one histidyl residue.
(18) Adlloy, 0.3 g or 3 g per body weight (kg), was fed orally with the basal diet consisting of casein, sucrose, bean oil, mineral, and vitamin mixtures.
(19) The protein efficacy of the krill meat slightly decreases in the course of canned food sterilization, However, their biological value remains high, being inferior to casein but insignificantly.
(20) The results of our study show that the substitution of soy protein for casein can be of benefit in those patients who need a long-term hypocaloric diet.
Lactoprotein
Definition:
(n.) A peculiar albuminous body considered a normal constituent of milk.
Example Sentences:
(1) In 6 volunteers with normal renal function, we investigated the effects of various kinds of protein (soy, lactoprotein and beef) and various amounts of an intravenously administered amino acid solution on glomerular filtration (GFR) and effective renal plasma flow (ERPF).
(2) In addition, tRNA populations during lactation correlated with the amino acids incorporated into the lactoproteins synthesized, which indicates adapation of the tRNA's to protein biosynthesis.

(8) Together with recommendation to use lactoprotein in the complex of shock therapy at all the stages of medical evacuation, the conclusion about necessity to perform at the early postshock period the differential component hemo- and anticoagulative therapy has been made.
(9) The 5' flanking sequences of all Ca-sensitive casein genes are conserved within the proximal 200 bp and contain several elements that probably function as cis-acting regulatory elements, including an octamer-like motif, and SV40-type core enhancer and a sequence that appears to be common to all lactoprotein genes.
