Chemical compounds in cells
Proteins
Structure of proteins
Protein acids are made up of smaller molecules called amino acids
Proteins form parts of cell membranes
Functions of proteins
Much of the structure of cells is made up of proteins
Proteins also make up many parts of the organelles within a cell
An Enzyme is a type of protein that speeds up many chemical reactions in a living thins
Lipids
Like Carbohydrates lipids are energy-rich organic compounds made of carbon, hydrogen, and oxygen
Lipids contain even more energy than Carbohydrates
Cells store energy in Lipids for later use
Elements and compounds
Compounds
when two or more Elements combined chemically they form a compound
The smallest unit of many compounds is called a molecule
Organic and inorganic compounds
Some important groups of organic compounds found in living things are carbohydrates, lipids, proteins and nucleic acids
Most compounds that contain carbon are called organic compounds
Compounds that don't contain carbon are called inorganic compounds
Elements
An Element is a substance that cannot be broken down to a simpler substance
An Element is made up of only one kind of atom
Elements found in living things include carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur
Water and living things
Most chemical reactions within cells could not take place without water
A cell without water is like a balloon without air
Nucleic acids
Nucleic acids are very long molecules made up of hydrogen, oxygen, carbon, nitrogen, phosphorus
Nucleic acids contain the instructions that cells need to carry out all the functions of life
There are two types of Nucleic acids. Deoxyribonucleic is the genetic material that carries information about an organism. Ribonucleic acid plays an important role in production of protiens
Carbohydrates
A carbohydrate is an energy-rich organic compound made of the elements carbon, hydrogen and oxygen
Sugars and starches are examples of Carbohydrates
Carbohydrates are important components of some cell parts
