Micro Molecules, Molecules, and Elements

This element is the backbone of all organic compounds and can form 4 bonds.

Carbon

This molecule is made of two hydrogen atoms and one oxygen atom.

Water (H₂O).

This macromolecule has a ring structure and provides quick energy.

Carbohydrate (e.g., glucose).

This type of molecule has long hydrocarbon chains and is used for energy storage.

Lipid.

This macromolecule contains nitrogen, a central carbon, a carboxyl group, and an R group.

Amino acid (building block of proteins).

This polymer is made of amino acids linked by peptide bonds.

Protein.

This molecule has a phosphate group, a sugar, and a nitrogenous base.

Nucleotide (building block of DNA or RNA).

What macromolecule do DNA and RNA belong to?

Nucleic acids.

This macromolecule is nonpolar, hydrophobic, and forms cell membranes.

Lipid (especially phospholipids).

This molecule looks like a double helix and contains the bases A, T, C, and G.

DNA.

What type of bond joins two monosaccharides together?

Glycosidic bond.

This macromolecule includes enzymes and helps speed up chemical reactions.

Protein

This molecule often appears as a hexagon or ring in diagrams and is a sugar.

Glucose (a monosaccharide).

This fat molecule has one glycerol and three fatty acids.

Triglyceride.

Which macromolecule has CHO in a 1:2:1 ratio?

Carbohydrate.

Which macromolecule contains elements C, H, and O but in no fixed ratio and includes long chains?

Lipid

Which macromolecule contains nitrogen and sometimes sulfur?

Protein.

Which macromolecule contains phosphorus (P)?

Nucleic acids.

This term refers to molecules made of many repeating subunits.

Polymer.

This molecule helps carry genetic information and uses uracil instead of thymine.

RNA.
