denatured vs rancid
« on: August 05, 2009, 02:00:13 am »
For fats or proteins, denatured is usually used in a cooking context, and usually authors are suggesting a subsequent ease of digestion. Rancid is usually used in a decomposition context and usually authors are suggesting that is not fit for human consumption. 

Is there any difference in structure between a protein of fat this is 'denatured' or 'rancid'??

I thought that proteins become denatured as they lose their tertiary shape and begin to break down into amino acids, and fats become rancid as they oxidize or glycate.

yes, that's what I understood to be, I just recently read some things that used the terms interchangeably and to apply to both proteins and fats so I didn't know at that point what difference the author was making?  oh well, it wasn't a scientific journal or anything so maybe the author just wasn't clear.
