Proteins Flashcards
How do proteins help in a structural way ?
They are the main component of body tissue sucb as muscle , skin , ligament and hair
How do proteins help as catalysts ?
All enzymes are made up of protein . Enzymes speed up reactions
How do proteins help with signalling ?
Many hormones and receptorsbare proteins
How do proteins help in an imunological way ?
All antibiotics that help fight illness are proteins
What are the two types of globular proteins ?
Insulin and hemoglobin
What are the two types of conjugated proteins ?
Hemoglobin and catalase
What are the three types of fibrous proteins ?
Keratin, elastase and collagen
Describe globular proteins
Spherical , one of the most commons types with multiple fold classes
Are globular proteins water soluble ?
Yes
Where is insulin produced ?
By beta cells in the pancreas
What does insulin do ?
It regulates metabolism or carbohydrates and fast by promoting glucose to be stored rather than used for energy
Describe conjugated proteins
A protein that must function in a pair with a non protein component (prosthetic group)
What are lipoproteins ?
When lipids combine with proteins
What are glycoproteins ?
When carbohydrates combine with proteins
What are metalions and vitamins ?
They form prosthetic groups called cofactors
Describe fibrous proteins
Elongated shape
What do fibrous proteins do ?
They provide structural support for cells and tissues
What is keratin found in ?
It is the main structural material in the outer layer of skin. It is the key component in hair and nails . Also provides necessary strength and toughness for the tongue and hard plate
What do fibrous proteins do ?
They are the main protein in extra cellular space in connective tissues in animals . Most abundant protein in animals
Are conjugated proteins soluble in water ?
Yes
Are fibrous proteins soluble in water ?
No
What does a long chain of amino acids make ?
a polypeptide chain
what is the primary structure of a protein ?
a polypeptide chain of amino acids joined together by peptide bonds
What causes the secondary structure of proteins to form their shape ?
the hydrogen bonds
