Biological Macromolecules Overview

Study Notes

Lipids

Organic compounds that are insoluble in water yet soluble in organic solvents.
Include natural oils, waxes, and steroids.
Key types: fats, oils, and waxes.

Carbohydrates

Organic compounds made up of carbon, hydrogen, and oxygen, typically in a ratio of 1:2:1.
Commonly serve as energy sources and structural components in living organisms.

Biological Macromolecules

Large complex molecules essential for biological functions; contrast with smaller micromolecules.
Four main types: proteins, nucleic acids, carbohydrates, and lipids.

Nucleic Acids

Complex compounds found in all living cells and viruses.
Composed of nucleotides, containing purines, pyrimidines, carbohydrates, and phosphoric acid.

Proteins

Substances consisting of amino acids, which are vital for various biological functions.
Composed of carbon, hydrogen, oxygen, and nitrogen.

Monomers

Small molecules that can join together through chemical bonds to form larger structures known as polymers.
Serve as the building blocks of biological macromolecules.

Polymers

Compounds formed by linking repeated simple monomers into larger molecules.
Naturally occurring (like DNA and proteins) or synthetic (like plastics).

Lipid Overview

Essential for storing energy, signaling, and acting as structural components of cell membranes.

Polymer Overview

Polymers can be natural (e.g., proteins, starch) or synthetic (e.g., nylon, plastics) and play critical roles in various fields, including biology and materials science.

Protein Enzymes

Proteins that act as catalysts to accelerate biochemical reactions in living organisms.
Essential for metabolic processes and regulation within cells.

Elements of Life

Key elements include carbon, hydrogen, nitrogen, oxygen, phosphorous, and sulfur, crucial for forming biological macromolecules.
