WebFibrous proteins have a secondary structure that is vital as it is made of alpha-helix or beta-pleated sheets. On the other hand, globular proteins have a tertiary structure that is important as is it bent and folded into a 3D spherical shape. Another difference is that fibrous proteins are insoluble in water, whereas globular proteins are ... WebThe amino acid sequence is irregular in globular proteins. Fibrous proteins are made up of regular amino acid strands. Examples. Hemoglobin, myoglobin, insulin and enzymes. Keratin, Collagen, Fibrin, Actin and Elastin. Role. Globular proteins are used to form enzymes, cellular messengers, and amino acids.
