Cell membrane
Membrane channelsEnzymesCell cell recognition
Collagen
Tensile strength to hold things togetherIncreases with ageNot water solubleResistance to digestive enzymes
Elastin
Holds everything together based on elasticityBecomes cross-linked unless elastic with ageNot water-solubleResistant to digestive enzymes
Muscle proteins
Myofibril proteinsContractile proteins
Keratins
Proteins of hair, wool feathers, clothes, horns, claws, and beaksHighly resistant to digestive enzymeHighly resistant to acid base or heat treatment
