peptides and peptones... grin

  #5

peptides >peptones

  #6

yes the correct answer to this is peptides....

then proteoses ,peptones ,amino acids are the end products of digestion by what enzymes????


  #7

Well protein are broken into small fragment like proteoses, peptones and polypeptides. by the enzyme PEPSIN.

These proteoses , peptones and polypeptide are further broken down by TRYPSIN, CHYMOTRYPSIN< CARBOXYPOLYPEPTIDASE AND PROELASTASE into Polypeptides and Amino acids.

Now the Polypeptides are broken down into amino acid by PEPTIDASES




  #8

Can any body tell me how to differentiate between proteoses, peptones and polypeptides?

thanks
