Marbelized fat

Question
QUESTION: I have a package of ground beef chuck patties? Can cattle have marbelized fat(MF) in their bodies? If so, would this meat, which has virtually no fat in it, have MF and would it and other fats cook out of the meat?

Thanks.

ANSWER: Dear Lee,

I'm not sure I understand your question, but I'll try to explain.
Marbelized is a term for the meat that has fat running through it. Fat itself is not marbelized (at least I have not heard of this term in another capacity).
So beef has fat in it--there are different amounts in different cattle and in different cuts of meat. Some of the juicier steaks have more fat = more marbeling. They taste better, but can be quite high in fat.
Some of the ground meat is made to be very lean, so there would only be, say, 3% fat in it. You'll notice when you make the hamburger that very little grease remains in the pan, as opposed to ground beef that will yield a whole lot more grease. Ground round or ground sirloin are both leaner cuts than ground chuck. These will make the lowest-fat burgers and you'll notice the least grease leftover in the fry pan.

QUESTION:   I have eaten meat that had what I would call fat. This fat is something I would try to cut out as best as I could because it would run throughout the meat itself. I think this what I would call "marbelized fat". It seems to hold onto the adjacent meat. It is definitely not cartilage. Is what I'm calling marbelized fat actually fat if you are saying all fat cooks out of meat.

 I guess ground sirloin and round would have the least grease and a different cut elsewhere would have maybe more
along with marbelized fat.

 Thanks.

Answer
Yes, it looks like we are both talking about the fat that runs through the meat, and no you can't cut it off like you can the fat along the edges.
I definitely wouldn't say "all fat cooks out of meat" but a significant amount does, and the more that comes out (in the fry pan)the more you know is in there.
The marbelized fat is essentially what is producing the grease.
