27. What is a prosthetic group? Identify prosthetic groups in the following conjugated proteins: A prosthetic group is a part of the protein that is not composed of amino acids. Lipoproteins Carbohydrates Hemoproteins Lipids Flavin nucleotides Metalloproteins Glycoproteins Phosphate groups Fe, Ca, Copper, Zinc Phosphoproteins Flavoproteins Heme (iron porphyrin)

Solution

part-a: Hemoproteins contain hemoglobin, in which \"iron (Fe2+) is the prosthetic group useful to carry oxygen

Part-b: Lipoproteins contain lipid moieties with double & triple bonds as prosthetic groups

Part-c: Metalloproteins such as cobalamin contain \"cobalt\" as prosthetic groups in their structure of intrinsic factor human digestive system

Part-c: Flavoproteins contain flavin as prosthetic group

Glycoproteins is conjugate protein that contains \"glycosidic linkage\" as prosthetic groups
