Protein Structure

Protein Shapes: Globular vs Fibrous

Description

Proteins can have globular or fibrous shapes, and these shapes help explain how they work in the body. Globular proteins are compact and usually fold into rounded forms. Fibrous proteins are long, extended molecules that often provide support and structure.

The shape of a protein is tied to its f...

As proteínas evoluíram para formar estruturas quaternárias e complexas multi-unidades quando moléculas maiores são necessárias pela célula em vez de ter cadeias de aminoácidos mais longas. A maioria das proteínas cai em uma das duas categorias, globular e fibrosa. As proteínas globulares são compactas com a cadeia de aminoácidos enrolada numa fo...
