Protein Types

Thermal energy

________ disrupts hydrogen bond and causes protein to unfold.

Hormones

________ and antibodies are also globular.

Denature

________- Protein loosing it's shape due to changes in conditions there are 2 types.

tertiary structure

Structure is long and coiled with little to no ________, have occasional crosslinks between chains which form fibers.

Iron

Haemoglobin -___ prosthetic group

Magnesium

Chlorophyll - ________ prosthetic group

Denature

Protein loosing it's shape due to changes in conditions

2 protein types

Fibrous and globular

Fibrous proteins

___________ are insolvable and denaturing resistant

Conjugated proteins

Proteins with another molecule attached called a prosthetic group

Permanent denaturing

Heat, heavy metals

Temporary denaturing

pH

How do Heavy metals disrupt proteins

Prevent formation of disulphide bonds needed for the protein to form the correct shape

What heavy metals disrupt proteins

Ag,Hg and Pb

Temporary denaturing

pH

How is pH temporary

Change in ph changes amino acid from a zwitterion and makes it charged this alters solubility and shape while pH is changed
