Discuss the 4 macromolecules that occur in nature including the building block unit of each different macromolecule

Proteins, nucleic acids, lipids and carbohydrates.

Explanation:

Proteins: The basic unit of proteins are amino acids. Proteins are organic compounds related to building metabolism. During the growth and development phases of the individual, there is an extraordinary increase in the number of cells that start to perform specialized functions, generating tissues and organs.

Nucleic acids: Its basic unit is the nucleotides. Present in the eukaryotic nucleus and dispersed in the prokaryotic hyaloplasma, nucleic acids can be of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both related to the mechanism of cellular metabolic control (cell function) and hereditary transmission of characteristics.

Lipids: the basic unit of lipids are fatty acid molecules associated with the glycerol molecule. Lipids are organic molecules formed from the association between fatty acids and alcohol, such as oils and fats. They are not soluble in water, but they dissolve in organic solvents, such as benzine and ether. They have a whitish or slightly yellow color. According to the nature of fatty acid and alcohol that form lipids, they can be classified into four major groups: simple, complex, derivatives and precursors.

Carbohydrate: The basic unit of carbohydrates are sugar molecules. Carbohydrates have as their main function the energy function. However, carbohydrates have functions that go beyond guaranteeing energy for cells, which are also related to the structure of nucleic acids and structural functions, for example.
