All right, so the four basic groups of biological molecules are polysaccharides, also known as carbohydrates, proteins, lipids, and nucleic acids.
00:19
These are the four main structures or types of molecules that make up all of biology, essentially.
00:26
The building blocks of firstly polysaccharides are monosaccharides, of course, also known as sugars, such as glucose, fructose, and sucrose.
00:35
Polysaccharides are insoluble in water as they are macromolecules, and so in aqueous solution, they remain as a suspension.
00:42
So technically when you, quote unquote, dissolve sugar into your drink, it isn't going from solid to aqueous or liquid.
00:50
It's actually just remaining in tiny little particles, which is known as a suspension.
00:55
Monosaccharides, however, can dissolve in water, so your straight sugar actually can be in aqueous form.
01:02
The building blocks of proteins are amino acids, and that i'll label as aa...
