Document Summary

We are tryi(cid:374)g to a(cid:448)oid the a(cid:373)(cid:373)o(cid:374)ia i(cid:374) urea, that"s a(cid:374) issue (cid:449)ith a high protei(cid:374) diet. Interactions between polypeptide chains: subunits within a given protein which can have different structure and function. Protein denaturation: disturbs their stability, denatured means: they uncoil and lose their shape, accomplished by: Loss of functional ability: heat, acid, other conditions, key points, digestion of proteins essentially begins in the stomach, hydrochloric acid uncoils proteins, exposing peptide bonds to pepsin, which is activated by hydrochloric acid. In the small intestine, pancreatic and intestinal proteases hydrolyze the polypeptide chains further until only amino acids remain and are absorbed. Sequencing errors: sickle cell compared with normal red blood cell, the result is increased energy needs, medical problems, and even death. Building materials: for growth, for maintenance or repair. Teeth, bone, skin, gut and obviously muscle (amongst all other cells in the body) also, the cells of your gi tract turnover every few days.
