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.
