What is fat? | Good Fat & Bad Fat Differences by CBSESolver | TRANS fat & CIS fat | TCS

 


Olive oil is 100% fat; there's nothing else in it. Pancake mix, on the other hand, is only about 11% fat.

And, yet, olive oil is good for you, and pancake mix is not. Why is that?

As it turns out, the amount of fat we eat doesn't impact our weight or our cholesterol or our risk of heart diseases as well as kidney diseases nearly as much as what kind of fat we eat. But let's back up:

What is fat?

If we were to zoom in on a salmon, which is a fatty fish, past the organs, past the tissues, into the cells, we would see that the stuff we call fat is actually made up of molecules called triglycerides, and they are not all alike. Here's one example.

Those three carbons on the left, that's glycerol. Now, you can think of that as the backbone that holds the rest of the molecule together. The three long chains on the right are called fatty acids, and it's subtle differences in the structures of these chains that determine whether a fat is, let's say, solid or liquid; whether or not it goes rancid quickly; and, most importantly, how good or how bad it is for you.

Let's take a look at some of these differences. One is length. Fatty acids can be short or long. Another, more important difference is the type of bond between the carbon atoms. Some fatty acids have only single bonds. Others have both single and double bonds. Fatty acids with only single bonds are called saturated, and those with one or more double bonds are called unsaturated. Now, most unsaturated fats are good for you, while saturated fats are bad for you in excess. For saturated fats, the story pretty much ends there but not for unsaturated fats. The double bonds in these molecules have a kind of weird property; they're rigid.


So, that means there are two ways to arrange every double bond. The first is like this, where both hydrogens are on same side and both carbons are on the same side. The second way is like this. Now the hydrogens and carbons are on opposite sides of the double bond. Now, even though both of these molecules are made up of exactly the same building blocks, they are two completely different substances, and they behave completely differently inside of us.

The configuration on the left is called CIS, which you've probably never heard of. The one of the right is called TRANS, and you probably have heard of trans fats before. They don't go rancid, they're more stable during deep frying, and they can change the texture of foods in ways that other fats just can't. They're also terrible for your health, by far worse than saturated fat, even though technically they're a type of unsaturated fat.

Now, I know that seems crazy, but your body doesn't care what a molecule looks like on paper. All that matters is the 3-D shape where the molecule fits, where it doesn't, and what pathways it interferes with.


So, how do you know if a food has trans fat in it?

Well, the only sure way to know is if you see the words, "partially hydrogenated" in the ingredients list. Don't let nutrition labels or advertising fool you. The FDA allows manufacturers to claim that their products contain "0" grams of trans fat even if they actually have up to half a gram per serving. But there are no hard and fast rules about how small a serving can be, and, that means, you'll have to rely on seeing those key words, partially hydrogenated, because that's how trans fats are made, by partially hydrogenating unsaturated fats.

So, let's go back to our olive oil and pancake mix from before. Olive oil is 100% fat. Pancake mix is only 11% fat. But olive oil is mostly unsaturated fat, and it has no trans fat at all. On the other hand, more than half the fat in pancake mix is either saturated or trans fat. And, so, even though olive oil has 10 times as much fat as pancake mix, it's healthy for you, whereas pancake mix is not. Now, I'm not trying to pick on pancake mix. There are lots of foods with this type of fat profile. The point is this: It's not how much fat you eat, it's what kind of fat. And what makes a particular fat healthy or unhealthy is its shape.

Earthquake | Why earthquake happens | Why are earthquakes so hard to predict? | TCS - The CBSE Solver

  Early Story:- In 132 CE, Chinese polymath Zhang Heng presented the Han court with his latest invention. This large vase, he claimed, could tell them whenever an earthquake occurred in their kingdom– including the direction they should send aid. The court was somewhat skeptical, especially when the device triggered on a seemingly quiet afternoon. But when messengers came for help days later, their doubts turned to gratitude. Today, we no longer rely on pots to identify seismic events, but earthquakes still offer a unique challenge to those trying to track them. So why are earthquakes so hard to anticipate, and how could we get better at predicting them?   Earth’s structure: To answer that, we need to understand some theories behind how earthquakes occur. Earth’s crust is made from several vast, jagged slabs of rock called tectonic plates , each riding on a hot, partially molten layer of Earth’s mantle . This causes the plates to spread very slowly, at anywhere from 1 to 20 c

Stones Formation in Kidneys & treatment of kidney stones | Kidney Stones

  The biggest kidney stone on record weighed more than a kilogram and was 17 centimeters in diameter. The patient didn't actually swallow a stone the size of a coconut. Kidney stones form inside the body, but unfortunately, they're extremely painful to get out.   Stones Formation in Kidneys- A kidney stone is a hard mass of crystals that can form in the kidneys, ureters, bladder, or urethra . Urine contains compounds that consist of calcium, sodium, potassium, oxalate, uric acid, and phosphate . If the levels of these particles get too high, or if urine becomes too acidic or basic, the particles can clump together and crystallize. Unless the problem is addressed, the crystals will gradually grow over a few weeks, months, or even years, forming a detectable stone. Calcium oxalate is the most common type of crystal to form this way, and accounts for about 80% of kidney stones . Less common kidney stones are made of calcium phosphate , or uric acid . A slightly different t

Why do some people get Bald? | Why Hair fall occurs | Why mostly men suffer Baldness

  What do Charles Darwin, Michael Jordan, and Yoda have in common? They, like many other historical and fictive individuals, are bald , in some cases by their own choice.   For centuries, a shining dome has been a symbol of intelligence, but despite this, many balding people still wish their hair would return. Scientists have long pondered,  "Why do some people lose their hair, and how can we bring it back?" Science behind Baldness- The full-headed among us have about 100,000 to 150,000 hairs on our scalps, and scientists have discovered two things about this dense thicket. Firstly , the sprouting hair we see is mostly made up of keratin , the protein leftover from dead cells that are forced upwards as new cells grow beneath them. Secondly , the structures that drive hair growth are called hair follicles , a network of complex organs that forms before we're born, and grows hair in an everlasting cycle. This cycle has three main phases. The first is anagen ,

Motion | A scooterist covers a distance of 3 kilometres in 5 minutes. Calculate his speed in:

 Class 9 Motion Physics 1. A scooterist covers a distance of 3 kilometres in 5 minutes. Calculate his speed in: (a) centimetres per second (cm/s) (b) metres per second (m/s) (c) kilometres per hour (km/h) Solution. (a) In order to calculate the speed in centimetres per second we should convert the given distance of 3 kilometres into centimetres and the given time of 5 minutes into seconds. Please note that 1 kilometre has 1000 metres and 1 metre has 100 centimetres. Now, Distance travelled =3 km   = 3 x 1000 m = 3 x 1000 x100 cm = 300,000 cm ----------------- (1) Time taken = 5 minutes = 5 x 60 seconds   = 300 s ------------------------------ (2)     We know that, Speed = Distance travelled / Time taken =   300,000 cm   / 300 s = 1000 cm/s --------------- (3)   Thus, the speed of scooterist is 1000 centimetres per second. (b) In order to express the speed in metres per second we should convert the given distance of 3 kilometres into metres and the
