- Simplest form of sugar and most basic units of carbohydrates

Function
-Energy supply for living organism by breaking down into carbon dioxide and water with the presence oxygen

Example
- Glucose 
- Fructose 
- Galactose

- Form by consisting of two monosaccharides (or can be call "double sugar ") joining together by undergoing dehydration reaction
- Link bond was glycosidic bond or can be call as glycosidic linkage too

- Function
- Normally people used it as sweetener
- When it is being digested , it will be broken down into simple sugars and providing energy
- help transporting monosaccharides such as glucose , fructose and galactose between cells
 
Examples
- Sucrose 
- Maltose 
- Lactose ]]> 2019-02-08 10:57:16 UTC https://padlet.com/limshumei/caul48e1roc7/wish/329136175 Carbohydrates limshumei https://padlet.com/limshumei/caul48e1roc7/wish/329142196 Polysaccharides
- Form by consisting of long chain of monosacharides linking together by glycosidic bond

-Function
-Serve as building material the cell or whole organism
- Energy storage that is hydrolyzed when it is needed
- Used to provide protective walls or lubricative caoating to cells

Examples
- Starch 
- Glycogen 
- Cellulose 
- Chitin

-triglycerides are lipids 
-Fats and oils are lipids 
-Low solubility in water 

Saturated fats 
- Fats that contain single bonds 
-Tend to be solid at room temperature 
Ex butter and lard 

Unsaturated fats 
- Fats that contains double bonds in one or more tails of the compound 
- Tend to be liquid at room temperature 
Ex vegetable oil

Functions 
-Being used as an energy source to provide energy 
- Structural component of of cell membranes 
- Store energy to insulates the body and cushion organs 

Examples 
-Phospolipids  
- Cholesterol 
- Vitamin D

- Has 4 structures
  • primary structure 
-linear sequence 
  • Secondary structure 
-Alpha helix 
-Beta plated sheets
  • Tertiary structure 
- Alpha helix and beta plated sheets collide with each other and form a 3D shape 
  • Quaternary  structure 
-When 2 or more tertiary structure polypeptide chains are arranged to form into a complex protein
- Amino acids are linked by peptide bonds

Functions
- Maintenance of body tissue , including repairing body tissue
- Source of energy
- Produces enzymes that increase the chemical rate of body

Examples
- Keratin 
- Hemoglobin
- Albumin

- Made up of molecules called necleotides
- Necleotides consist of a phosphate, sugar group and a nitrogen base
- Contains 4 nitrogen bases of A , T , G and C

Functions 
- Contains genetic information for the function of living things 
- Long - term storage of information ]]> 2019-02-08 12:22:15 UTC https://padlet.com/limshumei/caul48e1roc7/wish/329156186 RNA limshumei https://padlet.com/limshumei/caul48e1roc7/wish/329166653 - Single helix
- Nitrogenous bases include adenine (A), Guanine (G) , Cytosine (C) and Thymine (T)
- Polymers of nucleotide joined to one another by covalent bonds between phosphate of one necleotide  and another sugar
 
Functions
- Deliver amino acids to the ribosomes 
- mRna messenger for instruction protein 
- tRna carries the match of amino acids to condoms during translation ]]> 2019-02-08 13:01:55 UTC https://padlet.com/limshumei/caul48e1roc7/wish/329166653
