PROTEINS - Coggle Diagram
PROTEINS
Have four structures
Primary
Formed by covalent peptide bonds of amino acids
Secondary
Alpha helix
beta pleated
Tertiary
Disulphide bridge between sulfur containing amino acids
ionic bond
hydrophobic bonds
hydrophilic bonds
Quarternery
Made of more than one polypeptide
Amino acids are joined together to form proteins or a polypeptide
Carbon, Hydrogen, Oxygen and Nitrogen
Twenty Amino acids are present
Many proteins can be made
Proteins are linked together by peptide bonds
Peptide bonds are formed by protein synthesis
All proteins have a definite shape and size
Hydroxyproline is an example of a polypeptide
DNA is copied onto an RNA by transcription
RNA is made into polypeptide by translation
from cytoplasm
from nucleus
