No, collagen is a Fibrous protein. An example would be insulin.
Collagen is a structural protein found in the body, giving strength and support to tissues such as skin, bones, and connective tissues.
There are two class of protein based on their structure namely fibrous and globular. Globular proteins form a globe like spherical structure in contrary to rod like fibrous proteins (collagen). They are soluble in water and the structure is rendered by its three dimensional arrangement of amino acids in solution. Most of the enzymes, soluble hormones and factors fall into this class of proteins.
One example of a protein that is insoluble in water is collagen, which is a structural protein found in connective tissues such as skin, tendons, and bones. Collagen's insolubility in water is due to its triple helix structure and the presence of hydrophobic amino acid residues in its composition.
Collagen is a protein yes. Protein is a broad category of molecules.
Collagen is a long fibrous structural protein. A molecule of collagen contains three of the helical subunits coiled around each other in what is known as a coiled-coil. Hemoglobin on the other hand is a globular protein that contains a heme group. Four globular subunits make up hemoglobin and each contain an iron in order to hold the oxygen for transport.
Hemoglobin, Enzymes, Antibodies, Transporters in Membranes, Some Hormones (e.g. Insulin)
Tritiory proteins are globular proteins. Every enzyme is a globular proteins.
fibrous
collagen is a form of protein
No
Structural Protein
Yes, hemoglobin is considered a globular protein because of its compact, roughly spherical structure. It is also classified as a conjugated protein because it consists of a protein component (globin) and a non-protein prosthetic group (heme).
