Proteins Structure and Folding

Proteins Structure and Folding

1. 3 Tertiary structure:

   • The protein it starts to have like a 3d shape
     • This happen becuse differents interactions
       • This hapend because the R groups
         • R groups (Side Chain)
           • R group is very important in the amino acids becuse it difine the amino acids
             • This generated that the amino acids behave a certin way
               • Example
                 • hydrophilic
                 • Hydrophobic
       • For example :
         • Ionic Bonds
           • Van der walls
             • Disulfide bonds
               • Hydrogen Bonds

2. 4 Quartary structure

   • Proteins start to be of more than 1 polypedtide chain
     • Each polypedtide chain is a subunits
       • They interact betwen them
         • Disulfide bonds
           • Keep them together
         • Hydrogens bonds
           • Keep them together
   • Folding is made
     • Becuse the interactions of the amini acids

3. 1 Primary structure:

   • Sequences of amino acids
     • This are the bulidg blocks of the proteins
     • The amino acids are together by the peptide bonds
     • In sythesis amino acids are united to generated polypeptide
       • A protein is made of more than one polypeptide

4. 2 Secondary structure:

   • The sequences of amino acids are starting to folding
     • The most comun ways
       • Alpha helix
       • Beta-pleated sheet
         • The protein do one of this two depending in the amino acids arrangement
