Quizplus · Accepted Answer

Fibrous proteins have a long, narrow shape consisting of linear polypeptide chains that are bundled together. Examples include collagen, keratin, and elastin. Globular proteins have a more globose shape and are folded into a compact structure. Lipoproteins are a combination of protein and lipids, and tetrapeptides are short chains of four amino acids. Pleated sheets describe a repeating structure found in some proteins, such as beta sheets.
