Plant-albumin--flocculi on heating plant-juices; lencosin in wheat, rye, harley. Paralbumin (pseudomuein)--found in fluid of ovarian cysts. Native Albumins.--Soluble in distilled water; coagulated by heat. Globulins.--Insolnbl e in pure H20; soluble in dilute solutions of neutral salts (pptd. by excess); coagulated by heat; pptd. by current of CC)2, by diluting freely with H20, or by removing salt by dialysis. Serum-globulin (paraglobulin, fibrinoplastin)--2.2 % of blood-plasma. Fibrinogen--pptd. by saturating with NaCl; changed to tibrin by f.-ferment. Myosinogen (muscle-plasma)--yellowish fluid clot after death (rigor mortis); extracted with 10% NH4Cl, pptd. by excess of HjO. Cell-globulin. Crystallin (globulin)--25 % of crystalline lens. Globin--insoluble proteid, from spontaneous decomposition of hemoglobin. Plant-globulin--hemp, nuts, castor-bean, etc.; edestin in cereals. Derived Albumins (Albuminates).--S o 1 uble (when freshly pptd.) in dilute acids and alkalies; pptd. by neutralizing. Acid albumins--slightly alkaline reaction; syntonin formed in stomach by HC1. Alkali albumins--slightly acid reaction. Plant-caseins, or legumin--in almonds, oats, lentils, pease, and beans (nearly 25 %); insoluble in dilute alcohol. Fibrin--produced by clotting of blood, lymph, or chyle; elastic, gelatinous, fibrillar. Fibrins.--Slowly sol-Gluten-proteins--soluble in dilute alcohol; best uble in dilute acids or obtained by kneading wheat-flour on a sieve; 10 % NaCl. starch passes through; sticky, elastic gluten remains. Zein is a fibrin-like proteid in maize. Coagulated Proteids.--Dissolved difficultly Paracasein--produc...
