Karteikarten: Fundamentals of Protein Structure and Function — 14 Karten

Amino acids — definition?

Organic molecules with amino and carboxyl groups.

Peptide bond — formation?

Covalent bond between amino acids via dehydration synthesis.

Protein properties — roles?

Catalysis, support, transport, regulation.

Protein levels — order?

Primary, secondary, tertiary, quaternary.

Fibrous proteins — example?
