protiens

• protiens are made of amino acids.

globular protiens:

• compact, ball shape structure.
• includes enzymes, membrane protiens, receptors and storage protiens.

fibrous protiens:

• long and thin.
• have structural roles such as cologen.
• always composed of many polypeptide chains.

protien denaturing:

• 3D shape is lost if the hydrogen bonds break.
• polypeptide chain folds into a random coil.
• protien losses its function.
• temps above about 50 or very low PH.
