peptide bonds
protein digestion in stomach
basic structure of amino acid
how many essential amino acids?
how many nonessential amino acids?
secondary structure
protein digestion in small intestine
tertiary structure
denaturation of protein
protein absorption
primary structure
quaternary structure
gastrin releases HCl, HCl denatures proteins and converts pepsinogen to pepsin
two or more polypeptide chains bond together
unfolding of proteins occurring in presence of heat, acid, base, salt, or mechanical agitation
proteases released by pancreas, breaking down polypeptides to dipeptides and tripeptides, which are further broken down into amino acids
absorbed in small intestine, transported to liver from intestines via portal vein
single peptide chain, simple linear chain
amine group, R group (side chain), carboxyl group, hydrogen
eleven
join 2 amino acids together
nine
slightly folded and twisted
3D globular shape, folding of polypeptide chain
