Carbohydrates are in foods, some examples are sugars and starch. The structure of a carb is ring shaped, it is an easy one to know. The monomer of a carb is monosaccharide, which means one sugar. A monosaccharide consists of glucose, fructose and galactose. Carbs help give the body energy and help with storage. That is how Carbs help your body.
Lipids are made up of fats, butter oils and other things like that. An easy way to know that it is a Lipid is by it’s structure. It’s structure is either a chain of carbon singly bonded to each other for saturated and a chain of carbons with at least one double or triple bond for unsaturated. The monomer is a fatty acid. They have a few functions like, storage, controlling water movement and sending messages to cells. That is why Lipids are important to the body.
Proteins are made up of polypeptides, some examples are nuts and beans. The monomer of a protein is amino acids, there are 20 amino acids all together. The structure of a protein is a bit harder to recognize. It has the Amine group and functional group in it. Proteins are very versatile, their functions include carrying oxygen in blood, sending messages to cells, protecting from disease and breaking down substances. Also an enzyme is a protein that speeds up a chemical reaction. Proteins are very helpful to you as you can see.
Last but not least are nucleic acids. They consist of DNA, RNA, ATP etcetera. A difference between DNA and RNA is that DNA is double stranded and RNA is single stranded. The monomer of it is nucleotides. The structure is made up of sugar, phosphate group and a nitrogen Functions include the DNA containing all of your hereditary information and RNA uses your DNA to make proteins. This
