Proteins
• Primary Structure – Sequence of Amino Acids
– Met-Gly-Ser-His-Ala- Leu-Trp-Ile-Thr
• Secondary Structure – H bonding which
permits folds, pleats, sheets
• Tertiary Structure – Folding of the protein
into its final 3-D form
• Quaternary Structure – Proteins that have more than one subunit.
Amino Acids
• Amino acids combine to make proteins
Drawing the amino acids
Peptides and polypeptides
• Glycine and alanine can combine together
with the elimination of a molecule of water to
produce a dipeptide.
