Macromolecules: large molecules that are formed by joing smaller organic molecules together.
Macromolecules of Life
Carbohydrate:- These are very important to life because they are our main source of energy.-Subunits of this are sugars
-You would eat foods with glucose and starches, like breads and grains.- Carbohydrates are very essential to providing fuel to function, as well as giving essential vitamins and minerals.
Macromolecules are organized into 4 major categories: 1. Carbohydrates2. Lipids3. Proteins4. Nucleic Aids
Lipids:- Lipids also provide energy, as well as insulation and membrane structure.- Subunits of these are saturate/unsaturated fats, phospholipids, and steiroids.
- Foods you would eat to obtain lipids would be things high in fat, milk, and cholesterol. - Lipids primary function is to store energy.
Proteins:-Proteins make up about 15% of your body mass and are also involved in almost every function of your body.-A subunit of proteins are amino acids
-You would eat foods like meats, eggs, dairy, beans, and nuts.-Proteins are one of the most important macromolecules, they are used throughout the body
-You would eat foods like meat, fruits & vegetables, whole grains, and eggs which contain whole cells that include DNA and RNA in them.
Nucleic Acids:-Nucleic acids contain both DNA and RNA, they hold genetic information, so they are very important to life-A subunit of nucleic acids are nucleotides
