Chemistry of life

It explains how biological molecules interact to sustain life.

It only focuses on non-living matter.

It is unrelated to biological processes.

It is mainly about laboratory experiments.

Carbohydrates

Lipids

Proteins

Water

protein, oxygen, fat

protein, starch, fat

water, carbon dioxide, oxygen

water, starch, protein

Energy supply

Structural support

Cell recognition

Genetic information storage

form the membranes that surround mitochondria

act as a catalyst for cellular reactions

supply energy for the body

provide building blocks for amino acids

Saturated fatty acids have single bonds and are solid at room temperature, while unsaturated fatty acids have double bonds and are liquid at room temperature.

Saturated fatty acids have double bonds and are liquid at room temperature, while unsaturated fatty acids have single bonds and are solid at room temperature.

Saturated fatty acids are always found in plants, while unsaturated fatty acids are always found in animals.

Saturated fatty acids are hydrophilic, while unsaturated fatty acids are hydrophobic.

Long-term energy storage

Main structural component of the cell membrane

Catalyzing chemical reactions

Secondary source of energy

Glycerol and fatty acid chains

Amino acids

Monosaccharides

Nucleotides

One phosphate group and two fatty acid chains

Four carbon rings and no fatty acid chains

A chain of amino acids

A single glucose molecule

Steroids are composed of 4 carbon-based rings

Steroids contain fatty acid chains

Cholesterol is a type of steroid

Steroids are found in cell membranes

Peptide bond

Glycosidic bond

Phosphodiester bond

Hydrogen bond

Control the rate of chemical reactions

Store genetic information

Control movement of molecules across the cell membrane

Serve as a major functional component of living things
