Answer: Carbohydrates - monosaccharides
Protein - amino acids
Peptide - peptide
Lipid - fatty acids
Step-by-step explanation:
Carbohydrates - monosaccharides
A carbohydrate is a biomolecule that consists of carbon, hydrogen and oxygen atoms. The monosaccharides are the simplest kind of carbohydrates. They join together to form disaccharides (2-monosaccharides) and oligosaccharides (3-10 monosaccharides) and 11 or more monosaccharides form the polysaccharides.
Protein - amino acids
Proteins are the essential nutrients required by the human body. They are one of the building blocks of the body. Amino acids are the small structural units that make up the proteins. They join together to form the short polymer chains called as peptides. These peptides combine to form the proteins.
Peptide - peptide
Peptides are the short chains of amino acids that are linked by the peptide bonds. The simplest forms of peptides are dipeptides. A polypeptide chain forms the protein.
Lipid - fatty acids
Lipids are the compounds which are insoluble in water but they are soluble in organic solvents. Lipids include fatty acids, oils, cholesterol, and phospholipids.
