biological catalysts are proteins
many reactions requiring extremely high temps and days to complete are completed in an instant b/c of these
these serve as source of amino acids for embryos and infants
: egg albumin and casein in milk
specific protein molecules produced b specialized cells of the immune system in response to foreign anitgen.
These foreign invaders include bacteria and viruses
carry material from one place to another in the body. Thr protein transferrin transports iron from the liver to the bone marrow.
Hgb and myoglobin are involved in the transport and storage of oxygen
control many aspects of cell frunction, including metabolism and reproduction
many of the hormones that regulat body function are proteins (insulin)
provide mechanical support and provide for out covering
our hair and fingernails are largely composed of the protein keratin
our muscles including heart, contract and expand through the interaction of actin and myosin proteins- cilia, flagella
