Carbohydrates are a major source for living organisms. Our mitochondria break down carbohydrates and use the chemical energy released from its bonds to live. Carbohydrates have four functions, which include energy metabolism, structural components, and cell-to-cell contacts and recognition. The basic unit or monomer for carbohydrate is monosaccharide or simple sugars. An example of monosaccharide would be glucose, fructose, and galactose. Carbohydrates are composed of thousands of monomers are called polysaccharides. Some examples of polysaccharides would be starch, cellulose, and glycogen.
Proteins are very important. They provide structure. Organic catalysts are mostly made up of proteins. They are also used to store energy and act as chemical messengers to hormones and antibodies. Amino Acids are the monomers of proteins. The basic parts of an amino acid are an amine group, a carboxylic group, and a side chain and all attached to an alpha-carbon. There are two types of proteins, fibrous proteins which provide structure and are usually long and thin. Examples of fibrous proteins would be muscles, hair, cartilage, veins, and ducts. Globular proteins are proteins that transport oxygen and nutrients,
