Proteins. AICE Biology. Amino Acids. 20 essential amino acids Monomers of proteins. Amino Acids are made of:. -Central carbon -Carboxyl group (-COOH) -Amino group (-NH 2 ) -variable R group. Side Chain-Functional Group-R. Neutral and hydrophobic: Alanine (Ala); Leucine (Leu)
-Carboxyl group (-COOH)
-Amino group (-NH2)
-variable R group
Alanine (Ala); Leucine (Leu)
Cysteine (Cys), Glycine (Gly)
2. Ionic Bond
3. Disulfide Bond
4. Hydrogen Bonding
-H becomes positive
-N or O become negative
….Denatured (disruption in the conformation)
1. Select a conformational level.
2. Define the level.
3. Explain the role of bonding in the level.
4. Give an illustration or example.
-Secondary structure most important
-Insoluble in water
-Long, parallel polypeptides cross-linked
-Tightly folded polypeptide chains to form spherical shape
