Today we're going to talk about why hydrogen bonds are extremely important for organisms that are alive.
00:10
And so let's make us a list to talk about the reasons why hydrogen bonds are important to living things.
00:25
First, hydrogen bonds hold macromolecules together.
00:45
For example, remember that dna is made of nucleotides, and nucleotides are held together by hydrogen bonds.
00:54
So they form the rungs of the latter.
00:57
And so remember that the nitrogenous base adenine has two hydrogen bonds to thymine, and the same is true for the cg pairing that we all know.
01:11
These bonds in the middle here and here are hydrogen bonds.
01:19
So they hold the complementary strands of dna together.
01:22
The other really important thing that they do is they hold proteins in their three -dimensional structure.
01:32
So hydrogen bonds are really important in forming the three -dimensional and functional structure of a protein.
01:59
Number two, hydrogen bonds give water its solvent properties.
02:17
Remember, water is considered a good solvent, which means it can dissolve various solvents.
02:22
And so water's solvent properties are provided because of hydrogen bonding within that molecule or between water molecules.
02:34
Three, hydrogen bonding is important for cohesion...
