types of proteins

Question 1

globular proteins properties?

Answer 1

Compact, water soluble, spherical

Question 2

When do globular protein they form?

Answer 2

When proteins fold into their tertiary structures so that the hydrophobic R-groups on the amino acids are kept away AQ environment.

Question 3

example of a globular protein?

Answer 3

insulin

Question 4

what is insulin?

Answer 4

it is a hormone that regulates blood glucose concentrations

Question 5

what is the difference between conjugated proteins and globular proteins proteins ?

Answer 5

conjugated proteins contain contain a prosthetic group

Question 6

example of conjugated proteins

Answer 6

Haemoglobin

Question 7

What prosthetic group does haemoglobin contain?

Answer 7

Contains haem group, these contain iron

Question 8

What is a fibrous protein?

Answer 8

Fibrous proteins is a protein with an elongated shape. Fibrous proteins provide structural support for cells and tissues. Keratin, elastin and collagen are all examples of fibrous proteins

Question 9

What is karatin?

Answer 9

Fibrous proteins containing sulfur-containing amino acid, cyateine. This results in many strong disulphide bonds forming strong, inflexible and soluble materials.

Question 10

Where in the body is keratin found?

Answer 10

Hair, skin and nails.

Question 11

What is elastin?

Answer 11

Elastin is a quaternary protein made from many stretchy molecules. It is is found in elastic fibres. This allows structures to flexibility to expand when needed, but also recoil into the its original size.

Question 12

What is collagen?

Answer 12

Collagen is an connective tissue. There are a number of different forms but all are made up of three polypeptides wound together in a long and strong rope-like structure. Collagen does have some level of flexibility

Question 13

Where is collagen present in the body?

Answer 13

Skin, tendons, ligaments and the nervous system.
