Talk:Keratin
From Academic Kids
This text was removed; it needs more work before it goes back into the article:
Keratin molecules are helical and fibrous, twisting around each other to form strands called intermediate filaments. These proteins contain a high percentage of sulfur-containing amino acids, largely cysteine, which form disulfide bridges between the individual molecules resulting in a fairly rigid structure. Human hair is approximately 14% cysteine.
I wasn't the one who removed it, and don't have time to fix it yet; any takers?--maveric149
Re the discussion about whether keratin is present in teeth, see this http://www.rush.edu/worldbook/articles/011000a/011000006.html from the World Book Medical Encyclopedia - keratin is a primary component of tooth enamel.
If there are disputes about facts, some references would be nice as a way of resolving arguments. Graham Chapman
