Abstract:
The cryopreservation of sperm is a well established technique that plays an essential role in dissemination of elite germplasm of livestock. Despite having numerous advantages, the cryopreservation induces certain stresses on sperm including structural and functional damages leading to impaired sperm quality and fertility, which might be associated with production of reactive oxygen species (ROS). In addition, the ROS upon reacting with sperm lipids, DNA and proteins may lead to a cascade of sperm damages. The sperm membrane contains a rich amount of polyunsaturated fatty acids, which increases their susceptibility to oxidative stress induced damages, leading to formation of secondary products. These secondary products result in oxidation of sperm proteins via carbonylation. The carbonylation could lead to disturbances in specific proteins that are involved in capacitation. The present review deals with sperm protein carbonylation.

Nucleophilic Addition to the Carbonyl Group: General Mechanism
A stronger nucleophile can directly attack the electrophilic center, the carbonyl carbon. The HOMO orbital of the nucleophile interacts with the LUMO (π* antibonding) orbital present on the carbonyl carbon. This interaction breaks the π bond and shifts the π...
Alcohols from Carbonyl Compounds: Reduction
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...
