The main chemical components of living organisms are known as organic compounds. Organic compounds are molecules built around the element carbon (C). Living things are made up of very large molecules. These large molecules are called macromolecules because “macro” means large; they are made by smaller molecules bonding together. Our body gets these smaller molecules, the “building blocks” or monomers.
The four main types of macromolecules found in living organisms are:
Carbohydrates are sugars, or long chains of sugars. An important role of carbohydrates is to store energy. Glucose is an important simple sugar molecule with the chemical formula C6H12O6. Simple sugars are known as monosaccharides.
Plants store sugar in polysaccharides called starch. Animals store sugar in polysaccharides called glycogen.
Proteins are molecules that have many different functions in living things. All proteins are made of monomers called amino acidshat connect together like beads on a necklace . There are only 20 common amino acids needed to build proteins.
Enzymes are a type of protein that speed up chemical reactions. They are known as “biological catalysts
Lipids are molecules such as fats, oils, and waxes. The most common lipids in your diet are probably fats and oils. Fats are solid at room temperature, whereas oils are fluid.Creatures utilize fats for long haul vitality stockpiling and to keep warm. Nucleotides are made of a sugar, a nitrogen-containing base, and a phosphate gathering. Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are the two main nucleic acids. DNA is a double-stranded nucleic acid.
ATP (adenosine triphosphate), known as the “energy currency” of the cell, is also a nucleic acid.
Living beings are included natural mixes, particles worked around the component carbon. Living things are made of only four classes of natural mixes: proteins, sugars, lipids, and nucleic acids
