Proteins

Polymer

________- long repeating chain of smaller molecule joined together.

nitrogen

The elements that make up a protein- Carbon, hydrogen, oxygen, ________ and often sulphur.

Proteins

________ are polymers made from amino acids.

hydrogen bonds

The ________ form between the negative carboxyl group and the positive amino group.

Dipeptide

2 amino acids joined together is called a ___________.

Quaternary structure

________ occurs when a protein has several different polypeptide chains and then they fold up to fit together, this is a(n) ________.

amino acids

There are 20 ________ in the human body.

peptide bonds

The bonds between amino acids are called ________

polymer

long repeating chain of smaller molecule joined together

Polypeptide

Many amino acids joined together is called a _________

Structure of amino acid

Where does the bond between 2 amino acids form

between the amino group of one amino acid and the carboxyl group of another

What process does the bond between 2 amino acids form

Condensation

Primary structure

The chain of amino acids coded for by the DNA

Secondary structure

The simple structures formed when the ammino acid chain's fold and twist

2 shapes of secondary structure

They form alpha helix and beta pleated sheet shapes,

What holds secondary structures together

Hydrogen bonds between negative carboxyl group and the positive amino group

Tertiary structure

The proteins fold the 2 secondary shapes into complex 3d shapes

Held together by

Ionic bonds, disulphide bridges and hydrogen bonds

In tertiary structure where are the hydrogen bonds

Almost everywhere between R groups

Tertiary structure

The _________ is important to the function as in enzymes if the shape alters then the active site will alter causing the enzyme to no longer be complementary and thus not function

What could disrupt a proteins bonding

too hot, wrong pH, too saline or too many heavy metals
