Primary structure of proteins
1. Linear sequence of amino acids
2. Composed of peptide bonds formed between amino acids.
3. Formed during translation.
4. Involved in post – translational modifications.
Secondary structure of proteins
1. Folding of the peptide chain into an a-helix and 13-sheet.
2. Encompasses hydrogen bonds
3. Forms collagen, elastin action, myosin, and keratin – like fibres.
4. Involved in forming structures such as cartilages, ligaments, skins etc
