Peanut residues isolated from

Figure 13. Structures of chloroform-soluble residues isolated from peanut roots treated with [ C] PCNB. Chloroform-soluble accounted for 59.2% of the in peanut roots.

Insoluble residue accounted for only 2% of the applied in peanut cell cultures harvested 14 days after treatment with, [) C]PCNB however, insoluble residue accounted for 37X of the isolated from the roots of peanut plants 33 days after treatment. When peanut cell cultures were treated with... 

Methylene chloride-soluble residues. Methylene chloride-or chloroform-soluble C-labeled products were major residues in all of the plant tissues examined except peanut cell ciiltures (Figure 3). Chloroform-soluble C accounted for 59.2 of the radioactivity isolated from peanut roots 48 hr after treatment with [ C]PCNB. The radioactivity was in the form of PCNB (28.7 ), pentachloroaniline (22.5 ), pentachlorothiophenol (2.6 ) pentachlorothloanlsole (3.1 ) pentachlorothloanlsole sulfoxide (0.5 ) S-(pentachlorophenyl)-2-thioaoetic acid [(S-(PCP)ThioAcetate] (0.5 ) and S-(pentachlorophenyl)-3-thio-2-hydroxypropionic acid [S-(PCP)ThioLactate] (0.2 ) and S-(PCP)Cys (trace) (J), The structures of these compounds are shown in Figure 13. Based on TLC, the last three compounds in this list were classified as polar chloroform- or methylene chloride-soluble residues and the remaining compounds were classified as nonpolar residues. 

Figure 14. Methylene chloride- or chloroform-soluble residues were isolated from plant tissues treated with V C] PCNB. All tissues were treated for 3 days except lake water which is rich in blue green algae (9 h), peanut plants (2-day treatment/2-day post-treatment), and peanut cell cultures (1 day).

Protein isolates from milk, other animal products, and soybeans were widely used as adhesives and textile sizes in industry. Competition with man-made adhesives derived from petrochemicals has reduced the utilization of these protein adhesives. After extraction of oils from vegetable oilseeds, such as soybeans, peanuts, and cottonseed, the residual protein-containing meals have been useful in adhesives for the manufacture of plywood.
