See explanation below.
Work Step by Step
1
Fibrous proteins have relatively simple amino acid compositions and correspondingly
simple structures. They are key components of hair, wool, skin, and connective
tissue-materials that require strength and flexibility. Like synthetic polymers, these
proteins have a small number of different amino acids in a repeating sequence.
2
Globular proteins have much more complex compositions, often containing all
20 amino acids in varying proportions. Globular proteins are typically
more rounded and compact, with a wide variety of shapes and a correspondingly
wide range of functions.
