What are the functions of a protein?
EVEN SILLY DOGS CHASE TURTLES SHEEPS + SKUNKS E-Enzyme S-Storage D-Defense C-Contracile T-Transport S-Signal S-Structural
What does an enzyme do?
Changes the rate of chemical reactions w/o being changed itself
What does a storage protein do?
Source of amino acids for embryos
What does a defense protein do?
fights infections (antibodies)
What does a contractile protein do?
provides muscular movement
What does a Transport protein do?
Brings oxygen to other parts of the body (Hemoglobin)
What does a Signal protein do?
Messages from one cell to another (Hormones)
What does a structural protein do?
Fibers, like hair (Spider webs)
What are the four layers of protein folding? (Structures of a protein)
Primary, Secondary, Tertiary, Quaternary
What is the Primary structure?
smallest, amino acid sequence
What is the Secondary structure?
Coil and patterns: Alpha Helix (coiling, spiral) Or Pleated Sheet (Folded arrangement)
What is Tertiary Structure?
The overall 3D shape, Globular (pleated and helical) or Fibrous (helical)
