Yolk. When I was a child, I saw two eyes in the yolk of an egg at my aunt's house in the country. I asked curiously.
-
Egg yolk plug, egg white is like human amniotic fluid, which is used to protect the yolk and provide nutrition to the hatching chicks. Looks like the one who asked this question should be a child, haha.
-
Of course, the egg yolk is used to provide nutrients to the chick's development process.
-
Neither egg whites nor egg yolks. are all nutrients given to chicks.
If you eat live beads, you can see it.
-
It should be the egg yolk, because the chick hatches out yellow, and also, it comes out with egg whites, which should only be protective.
-
Yolk. Egg whites are just the nutrients that the chicks grow...
Specifically, you can go to this ** to take a look.
-
I'm a biology teacher, let me tell you. Not really. Did you notice a small white spot on the yolk when you beat the egg?
That's the placenta, which will develop into chicks in the future. The eggs we usually eat are unfertilized eggs. Fertilized egg farms have long been singled out.
Unless you specifically buy the kind of eggs that are fertilized.
In fact, we can also tell whether the egg is fertilized or not, that is, put it under the lamp and look at it. If the dot inside is very deep and large, it is fertilized, and if the dot is not, it is very small and light.
So what are egg whites and yolks used for? That provides nutrients for the development of the fertilized egg. But egg yolks provide the main nutrients. Egg whites can also ensure that chicks are not affected when they develop, and play a buffering role, which has the same function as our human amniotic fluid.
Got it?
-
It comes out of the eggshell.
-
The yolk hatches, and the egg white is nutritious.
-
The yolk is the embryonic part of the chicken.
Egg whites (egg whites) are the part of the cytoplasm that does not turn into chicks. The yolk is the one that grows into a chick and the embryo is inside the yolk. On the surface of the egg yolk, there is a thin film called the yolk membrane, that is, the cell membrane, which is the innermost protective structure in the internal structure of the egg.
Eggs, also known as chicken eggs and chickens, are eggs laid by hens. It has a hard shell on the outside and an air cell, egg white and yolk on the inside. Rich in cholesterol and rich in nutrients.
Eggs contain high protein, and the amino acid ratio of protein is suitable for human physiological needs, easy to be absorbed by the body, the utilization rate is as high as 98%, the nutritional value is very high, and it is one of the foods commonly eaten by humans.
-
The yolk has a small white dot on it, which is the placenta, which carries the nucleus and eventually develops into a chick, and the yolk and egg white are the ones for its development.
Provides nutrients.
Therefore, it cannot be said that the egg white or yolk has developed into a chick.
-
If you cook it, you won't eat it right away, but if you leave it for a while, it will have it, I think it's a chemical attack. It has something to do with protein.
-
It's that you've been boiling eggs for a long time.
-
It stands to reason that there will be none. If anything, it wouldn't be, would it?
-
Why does the yolk have a gray-green substance on the surface of the egg after it is cooked? What is the effect on the human body.
-
Eggs are a very nutritious substance. Eggs are also often eaten in our lives. After boiling the eggs, we will find that there is something very strange on the eggs.
When we boil the eggs, we will find that there will be a layer of green stuff inside the yolk of the egg. What exactly is the green thing? This substance is produced because of a chemical reaction that takes place between the yolk and the egg white during the process of boiling eggs.
1. Seeing the reaction of green substances in eggs in ordinary life, if we cut a boiled egg, we will find that there will be layers of gray-green things around the yolk of this egg. For some very experienced people, they don't dare to feel strange when they see these green substances, but the first information that comes to mind is that they have boiled this egg for too long. And for novice boiled eggs, they may think that these green substances are a harmful substance, and this egg thing can be eaten again.
The gray-green substance around the yolk does not cause any health effects on the human body, so we can still eat this egg. It can be seen that different people will react differently when they see the gray-green substance of eggs.
2. The reason for the production of green substances in eggs The reason why some gray-green substances are produced around the yolk in eggs is mainly because in the process of boiling eggs, some chemical reaction occurs between the egg white and the egg white, resulting in the formation of a gray-green substance. To be precise, the iron in the egg yolk reacts with the hydrogen and sulfur in the egg white to form ferrous sulfide. This ferrous sulfide is often grayish-green.
Therefore, when we boil eggs for too long, there will be a gray-green substance around the yolk.
3. SummaryFrom the above, we can know that boiling eggs for too long will cause some green substances to be produced around the yolk, so we should try to control the time of boiling eggs when boiling eggs.
-
This is a very normal phenomenon, as long as the hard-boiled eggs are left for a long time or placed in a warm environment for a long time, this layer of green things will be formed, it is completely non-toxic and harmless, and relatively speaking, the taste is better.
-
After the egg is cooked, there is a layer of green on the spring, which is a substance of the spring, and there is no problem with the nutritional value and quality that does not affect it.
-
During the heating process, the hydrogen and sulfur in the egg undergo a chemical reaction to form a substance called sulfur hydride, which is the green layer we see.
-
This is because the eggs have been boiled for too long, resulting in a chemical reaction of sulfur and hydrogen in the egg white and iron in the egg yolk, resulting in a gray-green substance called iron sulfide or ferrous sulfide, which is not easily absorbed by children.
-
When the eggs are boiled, there is a layer of green on them, and that is the egg. A manifestation of a relatively long period of time.
-
After the egg is cooked, the yolk has a layer of green, which is the one that protects the yolk, this is edible and very nutritious.
-
The main thing is the change in the composition of eggs, not all eggs are like this, only a few new eggs will have this ingredient.
-
After the eggs are boiled, the green layer is because the eggs are boiled in boiling water, so it will cause green things.
-
Why does the yolk have a gray-green substance on the surface of the egg after it is cooked? What is the effect on the human body.
-
What exactly is the layer of green stuff on the yolk of an egg when it is cooked? For this question, you should ask a nutrition expert to consult him, and he will tell you what it is? I think it's a very healthy thing, you can also go to the Internet and search for it, there should be the right answer on the Internet, just ask.
-
What exactly is the green layer on the yolk of an egg when it is cooked? When the eggs are cooked, there will be a layer of that green thing on top of the yolk, which I haven't seen.
-
There may be some green on this egg yolk. unclean substances, so you'll want to discuss with them what's going on.
-
The yellowing of egg whites after boiling is likely to be caused by egg deterioration, although spoiled eggs do not have a great impact on ordinary people, but it is not good to eat too much, and it is easy to have diarrhea.
In addition, please note: eggs have a variety of uses, can promote the growth of the baby, eggs can not only provide the human body with the best quality protein, but also rich in protective arteries, promote liver cell regeneration and strengthen the heart, brain trace elements selenium, zinc, chromium and other essential nutrients. The idea and practice of not daring to eat eggs and not daring to eat egg yolks lacks a practical basis.
There is another point to remind you to pay attention to: cool water pot, 3 minutes after the water is boiled, turn off the heat and simmer for 2 minutes, you can enjoy, the egg yolk at this time is just solidified, neither soft nor hard, amino acids and other nutrients are not destroyed, the best to eat.
-
The yolk is part of the cytoplasm, the yolk part grows into a chick, and the egg white provides nutrients during the hatching process.
The egg yolk is a real cell - the egg cell, and the egg whites and eggshells on the outside of the egg yolk are all non-cellular structures. The function of the eggshell is to protect the whole egg, reduce water evaporation, and have pores to facilitate gas exchange; Protein also acts as a buffer and provides nutrients and water for embryonic development.
Inside the cell, the yolk acts as a part of the cytoplasm that provides nutrients directly to the embryo, and the nucleus is located in a small white dot on the yolk, the placenta. The placenta will develop into an embryo in the future. If it is a fertilized egg, the placenta on the yolk will develop into an embryo, first absorb the nutrients of the yolk to develop various organs, and then absorb the nutrients of the egg white to accelerate the formation of feathers and weight gain, and finally become a chick with a broken shell.
-
It produces all the chicks.
The yolk generally has layers composed of yellow yolk and white yolk in concentric circles, and the yolk heart is in the middle. The yolk has a small white disc called the placenta (which looks like a small white dot), which is composed of a part of the cytoplasm and the nucleus, and the embryonic disc is light and small when the egg is not fertilized, and the embryonic disc is dark and slightly larger when the egg is fertilized.
After fertilization, the placenta can hatch chicks under suitable conditions. The placenta, yoline membrane, and yolk together make up the egg cell.
Eggs can carry bacteria during the formation process, and undercooked eggs cannot kill the bacteria and can easily cause diarrhea. Therefore, eggs should be eaten after high temperatures, and uncooked eggs should not be eaten.
-
First of all, we need to understand that the egg itself is an egg cell.
-
After hatching, it is the whole chick, and the protein is the nutrient.
-
All in all, egg whites provide nutrients to the chicks that are still in the eggs!
Don't do it alone, why don't you become bad.
The persimmon tree is planted from seeds.
The larvae that come out of the eggs are the larvae of the silkworm, and the (silkworm moth) is the adult of the silkworm. The life of the silkworm has gone through (four stages of egg, hatching, pupa and moth). >>>More
