Lysosomes Functions | Definition | Structure | Diagram

By | November 21, 2019

Lysosomes Definition Definition: Lysosomes are single-membrane vesicles, having an intermediate size between microsomes and mitochondria. These are surrounded by a lipoprotein membrane. Lysosomes contain hydrolytic enzymes like phosphatase and ribonuclease. Due to this, they are named as lysosomes (Lyso means lytic action). Lysosomes Functions are Described below: Lysosomes Location: Lysosomes are abundantly found in Eukaryotic Animal cells. They are present… Read More »

Proteins Functions | Definition | Types | Structure & Examples

By | November 21, 2019

Protein Definition: Proteins are basically biomolecules that high molecular weight polymers, polymers unruffled of α Amino acids.  α-Amino acids are joined to one another by Peptide linkage.  Peptide Linkage is represented as (-CO-NH-). Proteins are the most important elements of all living organisms. Proteins comprised of Carbon (C), Hydrogen (H), Nitrogen (N), Oxygen (O) and Sulphur (S). Proteins… Read More »
