What are the four basic subunits for each of the four major categories of biochemcials?

Better yet... what are the four major categories of biochemicals?!

Please help, I can't find the answer anywhere!

The four major categories of biochemicals are carbohydrates, lipids, proteins, and nucleic acids. Each of these categories has its own specific subunits.

1. Carbohydrates: The basic subunit of carbohydrates is a monosaccharide. Monosaccharides are simple sugars, such as glucose and fructose.

2. Lipids: Lipids are a broad class of molecules that include fats, oils, and phospholipids. The basic subunits of lipids are glycerol and fatty acids.

3. Proteins: Proteins are made up of amino acids. Amino acids are the building blocks of proteins, and there are 20 different types of amino acids used in protein synthesis.

4. Nucleic acids: Nucleic acids, such as DNA and RNA, are composed of nucleotides. A nucleotide consists of a sugar molecule (ribose or deoxyribose), a phosphate group, and a nitrogenous base (adenine, guanine, cytosine, or thymine/uracil).

To find this information, you can refer to biochemistry textbooks, online resources specializing in biochemistry, or academic databases that provide scientific articles related to the topic.
