Document Summary

Normal for body functions & health & required for muscle building. Proteins are made from 20 different amino acids, 9 are essential. Each amino acid has a central carbon (backbone), amino group (containing nitrogen) an acid group, a h(cid:455)d(cid:396)oge(cid:374) ato(cid:373) a(cid:374)d a side (cid:862)r(cid:863) g(cid:396)oup (cid:894)the (cid:272)o(cid:373)positio(cid:374) of the r g(cid:396)oup diffe(cid:396)e(cid:374)tiates the a(cid:373)i(cid:374)o a(cid:272)ids(cid:895) The synthesis of protein is determined by genetic information (dna which is transcribed into messenger mrna through transcription in the nucleus) Essential: must be supplied by the food s consumed. Conditionally essential: nonessential but becomes essential under certain conditions. Phenylketonuria: a condition where one is unable to break down phenylalanine in the body. Nonessential: the body can create it within, and does not need to be supplied through food. Amino acid chains are linked by peptide bonds in condensation reactions (removal of h2o) Amino acid sequences are all different which allows for a wide variety of sequences & length.
