Macromolecular structure and biological function of primary protiens
This document discusses primary proteins, their structure and functions. It begins with defining proteins as polymers of amino acids linked by peptide bonds. It then discusses the primary structure of proteins, which is the linear arrangement of amino acids. The key functions of proteins mentioned include acting as antibodies, enzymes, hormones, for transport, storage, as structural proteins, and contractile proteins. Some applications discussed are using proteins in coatings, food packaging, biotechnology, foods, microchips, and biomedical applications like hydrogels and targeted drug delivery.

- 4. TYPES OF PROTIEN GLOBULARPROTIENS • They are thread like molecule,lying side by side to form fibers in fibrous protien • They serve as a chief structural material of animal tissue • They are insoluble in water,chemically inactive FIBROUS PROTIENS • In globular protien the peptide chains are folded,looped and twisted • So molecule is more or less spherical • They are soluble in water,chemically active
