Final answer:
Globular proteins are water-soluble, nearly spherical proteins that play critical roles in bodily functions. They are characterized by having hydrophobic amino acids inside and hydrophilic amino acids on the surface. Examples include hemoglobin, enzymes, antibodies, and albumins.
Step-by-step explanation:
Globular proteins are a major class of proteins that are notable for their solubility in water and their compact, nearly spherical shapes. These proteins have highly reactive and hydrophilic surfaces due to the way they fold; the hydrophobic amino acids are typically tucked inside while the hydrophilic amino acids are on the molecule's surface. Hemoglobin, found in red blood cells, and enzymes are key examples of globular proteins. Other notable globular proteins include antibodies, hormones, and albumins, such as the egg albumin from egg whites and serum albumin in blood, which facilitate the transport of substances like fatty acids and help maintain osmotic pressure in the body.
