Carbon

The molecule of life with four valence electrons allowing it to form diverse structures by covalently bonding with up to four other atoms.

Organic Compounds

Carbon-based molecules that serve as the backbone for almost all molecules in cells, providing a wide variety of structures and possibilities.

Functional Groups

Parts of organic molecules that determine their chemical reactivity and function, with polar groups being hydrophilic and nonpolar groups being hydrophobic.

Biological Macromolecules

Carbohydrates, lipids, nucleic acids, and proteins are essential molecules for cellular functions, with carbohydrates serving as fuel, lipids for energy storage, nucleic acids for genetic information, and proteins for diverse structural and functional roles.

Nucleotides

The monomers of nucleic acids consisting of five types - adenine, guanine, cytosine, thymine, and uracil - each composed of a nitrogenous base, a 5-carbon sugar, and a phosphate group.

DNA

Deoxyribonucleic acid carrying genetic material in cells, composed of adenine, guanine, cytosine, and thymine bases, forming a double helix structure with complementary sides held together by hydrogen bonds.

RNA

Ribonucleic acid containing adenine, guanine, cytosine, and uracil bases, with a single-stranded structure and three types - messenger RNA, transfer RNA, and ribosomal RNA - playing crucial roles in protein synthesis.

Proteins

Diverse molecules crucial for various biological functions, including structural components like muscles and enzymes that act as catalysts to speed up chemical reactions without being consumed.
