Nucleic Acids

Nucleic Acids are made up of nucleotide units. These nucleotides are made up of a sugar, a base, and a phosphate. DNA and RNA are examples of what the nucleotides make. Nucleic Acids are very important to life for they transmit hereditary information. They also are energy carriers and are the main source of energy for your cells. If you didn't have nucleic acids you wouldn't be able to live because you couldn't even get the hereditary information you need to be born.

Carbohydrates

Carbohydrates are a major source of energy in your body, that provide you with energy on a short term basis. The body's digestive system breaks down polymers (starches) and turns them into monomers (glucose) for the body to then use as energy. Without enough carbs in your diet, you'll be fatigued easy and sick a lot. Your body simply wouldn't have enough energy to fight of the disease. To avoid this make sure to eat plenty of bread and pasta!

Lipids

Many people try to avoid lipids (or fat molecules) but they are essential to have. For example phospholipids are fats that are found in every cell membrane on an animal cell specifically used for structure. Without these you'd just be a blob of mush because nothing would be holding itself together.

Steroids are lipids that make hormones. Cholesterol is the most common hormone for these lipids to be making. Cholesterol is transported around the body in the bloodstream and if you have too much it may become stuck leading to a heart attack or stroke.

True fats (or triglyceride) are formed from an excess of glucose.

Proteins

Proteins are incredibly important to us, so much that the word itself is derived from the Greek term protos which literally means "taking first place" and that in itself says a lot. Proteins are made up of amino acids, their monomers, so if they are made up of monomers they are technically polymers. The protein's polymer is polypeptides. They stay together through peptide bond which link the amino acids together.


Every function in a living cell depends on the protein. All proteins in our body each have a specific function. Their functions vary between being involved in structural support, others in bodily movement, and some are even in defense against germs and due to all the different functions they have different structures.

If we didn't have proteins, we wouldn't have enzymes which be very bad for us. That is because enzymes are necessary to break down and release the energy we consume from food we eat.

Albumin is a type of protein that is contained in the white of an egg. Hormones too are a form of protein with biological regulatory functions. -Kaelie Looney
