Peptides & Proteins
(thanks to Hans Börner)

, Proteins & Peptides
Proteuos: Proteus (Gr. mythological figure who could change form)
proteuo: „"first, ref. the basic constituents of all living cells”
peptos: „Cooked referring to digestion”
Proteins essential for: Structure, metabolism & cell functions
2
, Bacterium
Proteins (15 weight%)
50% (without water)
• Construction materials
Collagen Spider silk proteins
3
, Proteins
Structural proteins
structural role & mechanical support
"cell skeleton“: complex network of protein filaments.
muscle contraction results from action of large protein assemblies
Myosin und Myogen.
Other organic material (hair and bone) are also based on proteins.
Collagen is found in all multi cellular animals, occurring in almost
every tissue.
• It is the most abundant vertebrate protein
• approximately a quarter of mammalian protein is collagen
