Presentation Transcript


Macromolecules

Proteins

pp 39 - 44


Proteins

Proteins are used for:

Amino acids.


Amino Acids


Amino Acids in Aqueous Solutions

What are the acid / base properties of the amino acid functional groups?


Amino Acids


Essential vs. Non-essential Amino Acids

  • non-essentialamino acids

  • essentialamino acids


Peptides

amide bond


Protein Organization

Four layers of protein organization:

  • primary (1°) structure

  • secondary (2°) structure

  • tertiary (3°) structure

  • quaternary (4°) structure


Primary (1°) Structure


Secondary (2°) Structure


Tertiary (3°) Structure

This provides the final 3-D protein structure.

Four major bond types between R groups:

  • H-bonding

  • ionic bonding

  • hydrophobic interactions

  • covalent bond (disulfide bridge)


Secondary (2°) and Tertiary (3°) Structure


Tertiary (3°) Structure


Quaternary (4°) Structure
