摘要: Abstract 1. 1.|With a simple preparative procedure, the proteins of rat incisors were separated into three fractions: enamel proteins; phosphoprotein(s), rich in aspartic acid and serine; collagen. The fractions accounted for approx. 4, 11 85% weight proteins, respectively. 2. 2.|Analytical data presented indicated that have distinctly different amino phosphate compositions. 3. 3.|These findings bear on proposal 4 phosphoproteins teeth are covalently attached to dentin
