(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.

(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.
Proteid
Definition:
(n.) One of a class of amorphous nitrogenous principles, containing, as a rule, a small amount of sulphur; an albuminoid, as blood fibrin, casein of milk, etc. Proteids are present in nearly all animal fluids and make up the greater part of animal tissues and organs. They are also important constituents of vegetable tissues. See 2d Note under Food.
Example Sentences:
(1) BTV antigen was dense in proteid yolk bodies and in the vitelline membrane of the developing oocytes.
(2) In the extracellular space of the tissue of the sponge Geodia cydonium, circular proteid particles are found which carry as subunits the aggregation factor and a series of glycosyltransferases.
(3) Cobaltous ions were not able to exchange the central atom of the metallo-proteide.
(4) The use and effectiveness of the nutrient was evaluated - globally - by a study of body weight according to the hydro-electrolytic balance and then - individually - by the balance of the intakes and secretions of the glucides, lipids and proteids.
(5) These dissimilar, separately derived droplets subsequently fuse, thus combining the materials that constitute the intraoocyte contribution to the proteid yolk.
(6) The variations were never statistically significant but for the Phenylalanine rate increase.--a non-systematic variation in the blood proteids that decreased as far as total proteids and albumin were concerned and that increased as far as globulins alpha1 and alpha2 were concerned.--Finally, no variations in the serous graphic record of lipid levels were noted, neither in the average of figures, nor in the analyses carried out after each bottle.
(7) It is supposed that the latter loose their coat and eventually transform into large proteid yolk spheres.
