What are the 4 macromolecules and what are they made of?
There are four classes of macromolecules (polysaccharides or carbohydrates, triglycerides or lipids, polypeptides or proteins, and nucleic acids such as DNA & RNA). Carbohydrates and lipids are made of only carbon, hydrogen, and oxygen (CHO). Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON).
What are proteins carbohydrates lipids and nucleic acids?
Carbohydrates, lipids, proteins, and nucleic acids are organic molecules found in every living organism. These macromolecules are large carbon based structures. The macromolecules are assembled by joining several smaller units, called monomers, together through a chemical reaction called dehydration synthesis.
What are the functions of each macromolecules?
For example, macromolecules provide structural support, a source of stored fuel, the ability to store and retrieve genetic information, and the ability to speed biochemical reactions. Four major types of macromolecules—proteins, carbohydrates, nucleic acids, and lipids—play these important roles in the life of a cell.
What macromolecule is RNA?
Ribonucleic acid, or RNA is one of the three major biological macromolecules that are essential for all known forms of life (along with DNA and proteins). A central tenet of molecular biology states that the flow of genetic information in a cell is from DNA through RNA to proteins: “DNA makes RNA makes protein”.
What are carbs proteins and fats?
Carbohydrates, proteins, and fats are the main types of macronutrients in food (nutrients that are required daily in large quantities). They supply 90% of the dry weight of the diet and 100% of its energy.
What monomer is DNA?
nucleotides
The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A), cytosine (C), guanine (G) and thymine (T).
What contains HDL?
High-density lipoproteins (HDL) are circulating particles composed of phospholipids, cholesterol, and proteins. There is a well established inverse correlation between plasma levels of HDL-associated cholesterol (HDL-C) and the incidence of cardiovascular disease.
What is HDL cholesterol in blood test?
HDL (high-density lipoprotein), or “good” cholesterol, absorbs cholesterol and carries it back to the liver. The liver then flushes it from the body. High levels of HDL cholesterol can lower your risk for heart disease and stroke.
What are the four major groups of biological macromolecules?
4 types of biomolecules and their functions.
What are the 4 main classes of mollusks?
– GASTROPODA (single shelled cowries, cones etc) – BIVALVIA ( two shelled like clams, mussels etc) – APLACOPHORA (solenogasters) – MONOPLACOPHORA (segmented limpets) – POLYPLACOPHORA ( or Amphineura as it was earlier called- Chitons) – SCAPHOPODA (tusk shells) – CEPHALOPODA (nautilus, squids, Cuttelfish, octopus etc)
What 4 elements make up most of the macromolecules?
Carbohydrates:
What are the 4 macromolecules essential for life?
Proteins.
