Question

define mutarotation and conjugated proteins

Answer 1

Conjugated protein given above
Mutarotation : Mutarotation is the change in the optical rotation because of the change in the equilibrium between two anomers, when the corresponding stereocenters interconvert. Cyclic sugars show mutarotation as α and β anomeric forms interconvert.
Conjugated proteins : A conjugated protein is a protein that functions in interaction with other chemical groups attached by covalent bonding or weak interactions. ... The non-amino part of a conjugated protein is usually called its prosthetic group. Most prosthetic groups are formed from vitamins

Answer 2

Answer:

Conjugated proteins are formed by the

binding of a simple protein with a non-

protein called the Prosthetic Group,

(nucleoproteins have nucleic acid as

prosthetic group).

Many highly complex proteins consist of

an aggregation of polypeptide chains held

together by hydrophobic interactions and

hydrogen and ionic bonds. Their precise

arrangement constitutes the quaternary

structure.

The conjugated proteins are of following

types:

(a) Nucleoproteins (prosthetic group

– nucleic acid) e.g., Protamines

(b) Metalloproteins (prosthetic group

- metal) e.g., Ferritin

(c) Chromoproteins (prosthetic group

– pigment) e.g., Cytochromes

(d) Phosphoproteins (prosthetic

group – phosphoric acid) e.g., Casein of

milk.

(e) Lipoproteins (prosthetic group -

lipids) e.g., chylomicron.

(f) Glycoproteins (prosthetic group -

carbohydrates) e.g., Mucin
