Chapter 23.1, Problem 1SSC

Interpretation Introduction

Interpretation:

Three proteins should be described with their functions.

Concept introduction:

Proteins are polymeric biomolecules which are formed by the polymerisation of amino acids. Amino acids are the organic molecules with $–{\text{NH}}_{\text{2}}$ and −COOH functional groups bonded on same carbon atom of the molecule.

They polymerise by peptide linkage to form dipeptide, oligopeptide and polypeptide molecules. Each peptide bond formation is a condensation reaction that occurs with the elimination of water molecule.

Explanation of Solution

The polymeric biomolecules which are formed by the polymerization of amino acids are known as proteins.

Three types of proteins are: Structural proteins (Collagen); Antibodies and Papain

The function of proteins is listed below:

1. Structural proteins provide structural support to the body. The most abundant class of proteins present in nature are known as structural proteins. These are fibrous proteins such as collagen that is utilized in the applications of cell structure. Structural proteins provide structural support to organisms for their survival such as Collagen. These are found in connective tissues such as ligament and tendons.
2. Antibodies help in the removal of foreign substances from the body and protect the body from infection. These are produced by plasma cells.
3. Papain shows the function of enzymes as well. This acts as a catalyst which breaks the proteins and form free amino acids.
