Proteins

1

Proteins are complex bio-chemicals containing?...

1

Proteins are made up of amino acids

1

Proteins are p__________________

1

If proteins are polymers ,and are made up of amino acids, then amino acids must be monosaccharides.

1

Some amino acids form Benzine ring structures

1

Carbohydrates form glycosidic bonds
Lipids peptide bonds
and Proteins form ester bonds during condensation reaction

1

A peptide bond can be reversed by hydrolisis

1

Roughly how many amino acids make 1 protein?

1

In a protein on which side is the amino acid group found? And what is it called in terms of 'terminus'?

1

In a protein on which side is the carboxyl group found? And what is it called in terms of terminus?

1

How many different amino acids are found in nature?

1

How many amino acids are in a dipeptide?

1

Water is released during a hydrolysis reaction.

1

What's the only difference between different amino acids?

1

What is the name of the test for proteins?

1

Biuret test: to test the sample it first has to be so you add a few drops of ___________________.

1

Then you add copper (II) sulfate so the solution changes colour

1

If the result is positive the solutions turns...?

1

The primary structure of proteins is made up of monomers called amine acids

1

Depending on the sequence of amino acids in the primary structure the secondary structure will be in the shape of a a-helix or b-pleated sheet...this is due to what type of bonding?

1

The tertiary structure is even more coiled/folded... what causes this?

1

Sometimes the tertiary structure is the last structure of a protein

1

Disulfide bridges occur between two cysteine amino acids in the polypeptide chain(s).

1

Between the two cystein amino acids bond by the sulphur atoms...this is ionic bonding.

1

the quaternary structure is how different polypeptide chains are held together by bonds.

Which do not use proteins
