Macromolecules are large molecules that are built from smaller organic molecules. Macromolecules are necessary for life and the four major macromolecules include: carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates are composed of monosaccharides (sugars), which provide quick energy for cells. Some examples of sugar include fructose, glucose, and galactose. These three sugars have the same chemical formula but different structures. Lipid cells store energy for long-term use. They are a diverse group of hydrophobic organic compound and include phospholipids, cholesterol, triglycerides, and steroid hormones.
Examples include saturated and unsaturated fats. Saturated fats are a solid at room temperature and are not very healthy and unsaturated fats are a liquid at room temperature and are usually a heathier option. Proteins are chains of amino acids held together with a peptide bond. Proteins are needed to preform many of life’s functions such as, defense that provides antibodies for immune system, enzymes which help speed up our reactions, and provide structure for our hair, skin, and nails. Lastly, nucleic acids are DNA and RNA Biomolecules Discussion.
The last complete meal I consumed was tonight’s dinner. My goal is to keep dinner easy and simple since I’m cooking for four people, so today’s menu included: chicken legs (cooked in a slow cooker), mashed potatoes, steamed baby carrots, and wheat bread. The main entrée was the chicken legs. Chicken is known to be low in calories and a high source of protein.
Mashed potatoes were served as a side dish and were made with potatoes, milk, and butter. Mashed potatoes are a carbohydrate with added lipids because of the butter and added protein because of the milk. Baby carrots were the vegetable of choice, also served as a side. Carrots are very high in fiber and are also carbohydrates. The bread that was served was regular bread bought from the grocery store, bread is also a carbohydrate Biomolecules Discussion.

The four major macromolecules in the body are carbohydrates, Lipids, Protein, and Nucleic Acid
Carbohydrates: are composed of monosaccharide’s which is a single sugar molecule chain together they contain carbon, hydrogen, and oxygen. Carbohydrates can be monosaccharides such as fructose, glucose, and galactose
Lipids: a diverse group of hydrophobic molecules that consist of phospholipids, cholesterol, triglycerides, and steroid hormones that It is all fat-soluble. The functions of lipids include storing energy, signaling, and acting as structural components of cell membranes Biomolecules Discussion.
Protein: performs many of life functions, a chain of amino acids they are not protein until they are bonded together with a peptide bond. They help in metabolism by providing structural support and by acting as enzymes, carriers, or hormones.
Nucleic Acids: are large molecules where genetic information is stored an important class of macromolecules found in all cells and viruses include DNA and RNA, Biomolecules Discussion.
This afternoon I didn’t feel like cooking so I decided to make a very basic homemade sandwich it consisted of white toasted bread, American cheese, and turkey breast ham. And yes it is the most basic sandwich but it was very good! Aside from the sandwich I had a small bag of barbecue lays and a cup of orange juice. The bread on my sandwich consisted of carbohydrates, which includes fiber and starch, the American cheese consisted of lipids, and the turkey breast consisted of protein.
The small bag of lays was mainly just carbohydrates and lastly, the cup of orange juice consisted of carbohydrates. In conclusion, my meal was not the healthiest option because my body took in carbohydrates and not much protein but it was a quick meal that in the end was really good.

The four sorts of macromolecules are carbohydrates, lipids proteins, and nucleic acids. I will explain their job and what they do to the best of my ability.
*Carbohydrates are composed of monosaccharides that consist of fructose, glucose, and galactose. Glucose is a simple sugar that is a component of starch and an ingredient in many staple foods. Carbohydrates are an essential part of our diet from grains, fruits, and vegetables and most items we eat. Carbohydrates are an important function in humans, animals, and plants.
*Lipids are a diverse group of hydrophobic organic compounds and include phospholipids (this is around every cell in your body), cholesterol (helps make hormones and is in plasma), and triglycerides (have a glycerol backbone and three fatty acid tails). Lipids also provide insulation from the environment for plants and animals.
*Proteins perform many of life’s function. Proteins provide structural support (hair, skin, and nails), transport (carry oxygen), enzymes (speed up reaction), movement (muscle contractions), defense (antibodies within your immune system).
*Nucleic acids carry instructions for the functioning of the cell. They carry DNA and RNA
I did not feel like cooking tonight after four straight hours of biology and preparing for the work week, so I went and bought chicken and rice for dinner. I know it is all bad due to the fact I ate more bad carbohydrates than good carbohydrates, but it is what my kids asked for Biomolecules Discussion. I am sure my cholesterol (lipids) probably spiked sky high with this deep-fried chicken and also the fried rice but it was worth not having to cook, Biomolecules Discussion.
Even the sweet and sour I dipped my chicken in was full of fructose corn syrup. I think the only good thing I put in my body during dinner was the water I drank, Biomolecules Discussion. I can’t even say the vegetables that were mixed in the fried rice were healthy.
