Question

Define the following as related to proteins:

Primary structure

Answer 1

Proteins:

• Proteins are very large molecules composed of basic units called amino acids.
• Amino acids are the structural and functional unit of proteins.
• Proteins help in the growth and development of the body.
• For example, actin, myosin, keratin, etc.

Classification of Proteins on the basis of structure:

Primary structure:

• A protein structure is a sequence of amino acids in a chain.
• They are all linked together to produce a protein molecule.
• The linear sequence of amino acids within a protein is called the primary structure of the protein.
• The primary structure is responsible for giving particular properties of the protein.
