Yes there is sugar in raw meat. Cooking meat creates much more AGEs than aging meat.
No, there is no sugar in raw meat, otherwise it would taste sweet.
We do not cook.

http://andersonclan.us/andersonclan_top/ages.html2.3 Glycations and AGEs, Defined
All the diverse sugars, and other carbohydrates we eat, are digested to simple sugars and absorbed into the blood stream. These blood sugars, glucose, galactose and fructose are reactive reducing agents. That is, they are capable of bonding to protein or lipid (fat) molecules, usually on an amine or a lysine group. So, like any fuel, they can be dangerous.
Glycation occurs when a reducing sugar molecule bonds to a protein or lipid (fatty acid) molecule without the controlling action of an enzyme which would normally control where the sugar bonds and its orientation. This puts the sugar molecule in the “wrong place,” on the protein or lipid molecule, thus forming a mis-shaped molecule our bodies cannot metabolize or dispose of easily.
