The trio developed a process known as palladium-catalysed cross coupling, a means of knitting carbon atoms together so that they form a stable "skeleton" for organic molecules.
这种蛋白质的分子多少像个球形，构成该蛋白质的氨基酸链的不同部分之间有内部交叉联结，正是这种力量使这些分子保持那种形状。
The molecules of this protein are more or less globular, and are held in that shape by internal cross-links between different parts of the amino-acid chain of which the protein is composed.
