no and no it holds the egg together
Chalazae (white strings) are there to anchor the yolk in the centre of the egg shell.
You must mean that stringy white stuff beside the yolk of an egg. That's not an umbilical cord. What you see is called the chalazae. Chalazae are strong protein strands designed to hold the yolk of the egg centered in the albumen (egg white). The chalazae in a real fresh egg are quite noticeable. They shrink or disappear as the egg ages in the shell. There is no umbilical need for avians (birds) since they are ovipositors. Egg layers have no need for umbilical cords as development takes place in a separate closed environment from the mother.
Chalazae are the pair of spiral bands holding the yolk of a bird's egg suspended near the center of the egg. Each of the spiral bands is called a chalaza.
There are two possibilities. The string hanging when you crack an egg into the pan or bowl when cooking is the inner membrane. This is the lining between the albumen and the shell and is attached to the inner shell. It often hangs from the broken shell after the rest of the egg has dropped into the dish. The white stringy thing in the egg next to the egg yolk is called the chalazae. This is a strand of protein that centers they egg yolk in the albumen (the egg white) The freshest eggs have two, most store bought eggs have only one visible if any as they fade away as the egg grows stale.
The twisted strand in egg whites is called a chalaza. It is a structure that helps hold the yolk in place within the egg.
The white string-like structure inside a chicken egg is called the chalaza. It anchors the yolk in the center of the egg and helps prevent it from moving around. It is safe to eat and does not indicate spoilage.
They're called the chalazae. Their purpose is to hold the egg yolk in the center of the albumen. There is one on either side of the yolk, and they attach to the inside of the shell wall.
Egg whites, also called albumin, consist of several distinct layers. Chalaziferous white: This innermost layer surrounds the egg yolk. It is like a protective capsule, which protects the yolk in the center of the egg. Chalazae are more prominent
They are call chalaza and are strands of protein that hold the egg yolk centered in the albumen. The fresher your egg is the more prominent the chalazae are and they are perfectly edible. Once cooked they are not visible and are similar to the material of the egg white. Stale eggs will have had them but they will have disappeared as the egg lost moisture.
-yellow -slimy -runny -half liquid, half solid -Dude, go to your fridge, get an egg, and crack it open. Look at it. Then you can eat it (but not raw)
In the eggs of most birds and reptiles, the chalazae are two spiral bands of tissue that suspend the yolk in the center of the white (the albumen). The function of the chalazae is to hold the yolk in place.
