3-dimensional structure of hemoglobin, a globular protein. In biochemistry, globular proteins or spheroproteins are spherical ("globe-like") proteins and are one of the common protein types (the others being fibrous, disordered and membrane proteins).

Globular proteins are named for their approximately spherical shapes and are the most abundant proteins in nature. The globular proteins exist in an enormous variety of three-dimensional structures.

Globular proteins are round structures. Like their name, globular proteins have a round, spherical formation. This is because the hydrophobic parts of the protein fold inwards while the hydrophilic parts become arranged around the external surface. Globular proteins are water soluble.

Mar 6, 2025 · Some proteins are globular (spherical), compact and water-soluble, while other proteins are fibrous and elongated, physically tough, and water-insoluble. Chemical bonds are responsible for the shapes that proteins maintain.

May 5, 2021 · What Globular Protein is? A Globular protein is a Spherical or Globular shaped protein, made by the folding of different segments of a poly-peptide chain. These are the the most abundant proteins in nature.

Dec 3, 2024 · Globular proteins form a spherical shape when folding into their tertiary structure because: Their non-polar hydrophobic R groups are orientated towards the centre of the protein away from the aqueous surroundings. Their polar hydrophilic R groups orientate themselves on the outside of the protein

Dec 26, 2024 · Haemoglobin is a globular protein which is an oxygen-carrying pigment found in vast quantities in red blood cells. It has a quaternary structure as there are four polypeptide chains. These chains or subunits are globin proteins (two α–globins and two β–globins) and each subunit has a prosthetic haem group
