Document Summary
Lecture 6 chapter 6 protein: amino acids. Question, what could possibly be bad about a high protein diet (say 100g/day over 50g/day) Ammonia we are trying to get rid off as its quite toxic for us. 40% body protein in skeletal muscle, 25% in body organs, and the rest in the skin and blood. Good sources: meat, milk, eggs, legumes, grains and vegetables: will get all amino acids needed from meet but not everything. Proteins can be classified by function: enzymes (generally contain suffix ase, hormones (e. g. , melatonin, insulin, structural elements (e. g. , actin, myosin) Immunoproteins (e. g. , antibodies: transporters (e. g. , albumin, hemoglobin, other roles will (cid:271)e dis(cid:272)ussed i(cid:374) this le(cid:272)ture . Interactions between polypeptide chains: subunits within a given protein which can have different structure and function. The result is increased energy needs, medical problems, and even death. Roles of proteins: building materials, for growth, for maintenance or repair.
