Front (Question)

What functional groups does an amino acid contain?

Back (Answer)

Amino group and carboxylic acid group

Front (Question)

Amino acids can combine in what type of reaction?

Back (Answer)

A condensationreaction

Front (Question)

If 2 amino acids combine what is produced?

Back (Answer)

A dipeptide

Front (Question)

If 2 different types of amino acids combine what will be produced?

Back (Answer)

2 different types of dipeptide

Front (Question)

What is produced when more than 2 amino acids combine?

Back (Answer)

A polypeptide which leads to protein formation

Front (Question)

What does R represent in… Glycine (2-aminoethanoicacid) Alanine (2-aminopropanoicacid) Serine (2-amino-3-hydroxypropanoicacid)

Back (Answer)

Glycine- H Alanine- CH3 Serine- CH2OH

Front (Question)

What is a primary protein structure?

Back (Answer)

The precise sequence of amino acids in the protein chain - many sequences with different amino acids

Front (Question)

What is. Secondary protein structure

Back (Answer)

How parts of the protein fold up to form an alpha helix (held in shape by hydrogen bonds involving peptide link) or a beta pleated sheet (paper shape stabilised by hydrogen bonds between amino acids in different polypeptide chains) Results in hydrogen bonding Occurs between N-H and C=O groups of polypeptide chains

Front (Question)

What is a tertiary protein structure

Back (Answer)

Proteins as a whole and the way in which alpha helices and beta pleated sheets of protein fold with respect to eachother This structure is held together by interactions eg Intramolecular- covalent and ionic bonds Intermolecular - VDW and H bonds

Back (Answer)

#11

Front (Question)

Draw alkaline hydrolysis of peptide/amide link

Back (Answer)

#12

Front (Question)

What do amino acids predominantly exist as and what are these?

Back (Answer)

Zwitterions: these are internal sales and neutral molecules

#13

Front (Question)

Draw a zwitterion

Back (Answer)

#14

Front (Question)

Draw the zwitterionic nature of amino acids in acidic conditions

Back (Answer)

#15

Front (Question)

Draw the zwitterionic nature of amino acids in alkaline conditions

Back (Answer)

#16

Front (Question)

What are the properties of amino acids?

Back (Answer)

High melting points- have strong ionic bonding (IMF) lots of energy to overcome bonding and melt Soluble in water due to ionic properties

#17

Front (Question)

In acid hydrolysis of the amide peptide link what do u add

Back (Answer)

H3O+ H2 to N OH to c

#18

Front (Question)

Alkaline hydrolysis of amide peptide link what is added

Back (Answer)

NaOH H to N Na+O- to C
