Document Summary

Plants vs. animals = diff. combo of amino acids: plants proteins not easily absorbed. 9 essential aa: ca(cid:374)"t (cid:271)e (cid:373)ade (cid:271)y (cid:271)ody; (cid:272)o(cid:374)su(cid:373)ed thru diet, complete proteins: have all 9 essential aa, animals. 11 nonessential aa: can be made by body. Incomplete protein: lack 1+ essential aa: plants, lack 1+ essential aa. Four levels of protein structure: primary, aa + aa + aa + aa , polypeptide chain, secondary, hydrogen bonds form 1) alpha-helices (swirly) and 2) beta pleated sheets, tertiary, more folding, quaternary, polypeptide + polypeptide + polypeptide , protein formed! Genes turn on/off to drive/stop making certain proteins. Body pick/choose from amino acid pool to make specific proteins. Transamination: body lacks on of 11 nonessential aa, body can make similar one, but (cid:272)a(cid:374)"t (cid:373)ake the 9 esse(cid:374)tial aa, la(cid:272)k o(cid:374)e of 9 esse(cid:374)tial aa = protei(cid:374) can"t (cid:271)e sy(cid:374)thesized.
