Amino acids are the subunits that make up proteins.
The sub-unit is the amino-acids.
Amino acids
Proteins are composed of amino acids. These amino acids are joined together by peptide bonds where the -COOH group and the -NH2 group of two consecutive amino acids bond with the loss of a water molecule. The sequence of the amino acids make up the primary structure of the protein.
The subunits that make up proteins in most living things are twenty different amino acids. Google amino acid at wiki.
Nucleotides are repeating subunits that make up DNA.
Collagen is a long fibrous structural protein. A molecule of collagen contains three of the helical subunits coiled around each other in what is known as a coiled-coil. Hemoglobin on the other hand is a globular protein that contains a heme group. Four globular subunits make up hemoglobin and each contain an iron in order to hold the oxygen for transport.
Two subunits that make up a fat molecule are glycerol and fatty acids. Glycerol is made of carbon, hydrogen, and oxygen and fatty acids consist of hydrogen atoms, chains of carbon, and a carboxylic acid group.

The subunits making up nucleic acids are nucleotides
carbohydrates dna subunits are nucleic acids. Nucleic acid subunits are nucleotides.
The subunits that make up polysaccharides are sugars, or monosaccharides. An example of a monosaccharide is glucose, which we need for energy.

monosaccharide
Their RNA or DNA (depending on the virus) is surrounded by a capsid: a protein coat made up of subunits of protein called capsomers
fatty acids and steroids
The three subunits that make up a nucleotide are:a phosphate groupa 5-carbon sugar(deoxyribose)a nitrogen baseNucleotides are organic molecules that serve as the monomers, or subunits, of nucleic acids like DNA and RNA.
