Sorry, today I don't have my whiteboard with me, so I'm going to draw it on a piece of paper.
00:00:08
Let's see if you can understand.
00:00:15
Okay, so the last day we started with carbohydrates and lipids.
00:00:17
Today we continue with another one of the biomolecules, which are the proteins.
00:00:21
Okay, so what are the proteins?
00:00:32
okay they are formed okay our outline okay they are formed by amino acids what
00:00:36
are amino acids are the basic units of the proteins okay so since they are the
00:00:48
basic units we are going to on the line there are 20 amino acids I'm going to
00:00:55
short it out like that that form all the proteins okay these form all the proteins
00:01:03
they are not more nor less but 20 of them for all the proteins okay the functions of these proteins
00:01:11
functions okay there are three basic functions of proteins okay to see how important they are
00:01:20
Basically, the form structures, for example, we have our nails, they are made out of proteins, did you know?
00:01:29
And the protein that make up the nails are the keratin.
00:01:41
Maybe you have heard about it from some shampoos that has keratin, okay?
00:01:48
But naturally, we have it in the nails, we have it on the hair.
00:01:55
Also, they regulate metabolism. An example of these are enzymes that make really important reactions in our body.
00:01:58
And also, they perform some biological functions.
00:02:15
For example, the hemoglobin, which is the enzyme which is inside the red blood cell, and they carry the oxygen.
00:02:23
Okay, one thing about this amino acid is that there are some essential amino acids.
00:02:37
This is important, okay?
00:02:44
They are essential amino acids that we cannot construct inside our body,
00:02:46
but we need to take it with the nutrients, with food.
00:02:55
So, they are obtained from the diet.
00:02:59
That means that we need to eat them in order to have them.
00:03:05
Then another of the organic functions are the nucleic acids
00:03:08
Yeah, these all are organic molecules
00:03:15
I will tell you about them now
00:03:20
Okay, nucleic acids
00:03:22
They are formed by nucleotides
00:03:25
They are formed by nucleotides
00:03:29
This is the basic unit
00:03:33
So we have the line
00:03:36
And there are two types
00:03:37
RNA
00:03:39
And DNA
00:03:40
Riboxirribonucleic acid
00:03:43
Deoxyribonucleic acid
00:03:47
Okay
00:03:49
And the functions of these two
00:03:50
Because maybe you have heard about the DNA
00:03:54
But not the RNA
00:03:56
They are
00:03:58
One helps the other
00:03:58
Okay
00:04:01
In our body
00:04:02
Basically the function is to store the genetic information
00:04:03
store the genetic information we have blue eyes or blonde hair for example and also they synthesize
00:04:07
proteins they synthesize proteins okay both functions i hope you understand my writing please
00:04:20
Now with the proteins, nucleic acid plus the carbohydrates and lipids
00:04:36
As we wrote the other day, we're going to write that they are organic
00:04:43
Okay, so we write
00:04:48
We write organic for carbohydrates, lipids, protein and nucleic acids
00:04:51
Now we start with the inorganic biomolecules
00:05:00
okay we have two inorganic biomolecules we have mineral salts and water okay what are mineral
00:05:05
salts think a little bit about about them okay there are a most of them ions what are ions
00:05:17
think about chemistry well yeah you should have learned about it okay they are electrically
00:05:28
charge, okay? Positive or negative, okay? So we have, for example, calcium. Do not copy this,
00:05:34
okay? No, this is not. Calcium, for example, which is positive, or we have chloride, which is
00:05:43
negative, okay? These are ions. As I say, don't copy this, okay? Now, what are the functions
00:05:50
of these mineral salts, okay? The functions of these minerals are two types. They can be
00:05:57
structural. For example, the calcium that we said before, we use it for the bones, to construct the
00:06:05
bones. Or they are regulatory, regulatory, because they are going to work on metabolic reaction.
00:06:13
There are many ions that work on the metabolic reaction.
00:06:25
Water, the most important inorganic biomolecule in our body, H2O, okay?
00:06:33
As you already know, we are mostly made of water, okay?
00:06:43
And we can say we're going to make a summary of the properties, okay?
00:06:49
the function is a universal solvent, which means that it's going to dissolve things.
00:06:54
For example, the mineral salts can be dissolved into water, okay?
00:07:05
And this is going to help with metabolic reactions, okay?
00:07:10
Also, for transporting, if we want to transport something, for example, in blood, we use the
00:07:14
plasma, which is mostly made of water.
00:07:22
And also temperature regulation
00:07:24
Temperature regulation
00:07:28
Water is going to regulate
00:07:31
Our temperature in our body
00:07:35
It's very important this
00:07:38
And these are the inorganic biomolecules
00:07:39
And finally
00:07:44
But not the less important
00:07:45
Vitamins
00:07:51
okay vitamins can be either organic or inorganic that's why we made it in another sections okay
00:07:53
they are of a variety chemical composition okay we have a variety chemical composition
00:08:00
and they are needed in small quantities so meaning that we don't need too much vitamin
00:08:10
but just a little bit of them and are very important for our body okay there are two types
00:08:20
Okay, we have the fat soluble and the water soluble, which means that some of them dissolve in fat, some of them dissolve in water.
00:08:25
Okay, properties of each.
00:08:42
These fat soluble, they are stored in the liver.
00:08:46
Okay, and for example, our vitamins A or D.
00:08:53
so if we have too much of these proteins then we have a problem if we have too little of these
00:08:59
proteins we have a problem too okay vitamin a is good for your eyes okay eat many carrots that
00:09:06
they have vitamin a and d okay it's good for your eyes okay a water soluble are not stored
00:09:14
So we need to take them all the time
00:09:22
For example, B12
00:09:27
We call it folic acid, for example
00:09:31
Or vitamin C, that is good in this time
00:09:34
When you can get the flu, for example, or coronavirus
00:09:38
So it's good to have a lot of vitamin C in your body
00:09:41
Remember that your outline finally has to look something like this
00:09:44
okay so we will need to occupy the whole page that you have to write here organic here inorganic
00:09:49
the vitamins apart okay and everything has to appear in your notebook
