Document Summary

Bchm 270: module 1 molecular basis of health and disease. 1. 0 intro to biochemical basis of health and disease: biochemical basis of health and disease: humans have evolved to function in a way that allows the build up and break down of chemical molecules to suit changing needs. In the normal healthy state, out cells work together as tissues to handle the day-to-day process of life. Some tissues and organs have specialized to produce different molecules and messages. Nucleotide: organic molecule; basic structural unit for deoxyribonucleic acid (dna) and ribonucleic acid (rna). Atp (adenosine triphosphate ): important nucleotide; (cid:862)e(cid:374)e(cid:396)g(cid:455) (cid:272)u(cid:396)(cid:396)e(cid:374)(cid:272)(cid:455)(cid:863) of the (cid:272)ell. Gtp (guanosine triphosphate): identical to atp, except has guanosine instead of adenosine; another primary cellular energy source. used for only certain processes, like protein synthesis and gluconeogenesis. Dna: i(cid:374) the (cid:272)ell(cid:859)s (cid:374)u(cid:272)leus, built from two antiparallel strands of nucleotides which interlock through h-bonding between the n- bases.
