Carbohydrates- Structure, Properties, Classification and Functions

Classification of Carbohydrates

Carbohydrates- Structure, Properties, Classification and Functions The carbohydrates are a group of naturally occurring carbonyl compounds (aldehydes or ketones) that also contain several hydroxyl groups. It may also include their derivatives which produce such compounds on hydrolysis. They are the most abundant organic molecules in nature and also referred to as “saccharides”. The carbohydrates which … Read moreCarbohydrates- Structure, Properties, Classification and Functions

Glycolysis- Steps, ATP generation and Significance

Glycolysis- Steps, ATP generation and Significance

Glycolysis- Steps, ATP generation and Significance Fermentation and respiration are two major strategies for energy conservation in chemoorganotrophs. The glycolytic pathway is a major metabolic pathway for microbial fermentation which involves the catabolism of glucose into pyruvate. It is also called the Embden–Meyerhof–Parnas pathway for its major discoverers. Regardless of whether glucose is fermented or … Read moreGlycolysis- Steps, ATP generation and Significance

Differences between Exotoxins and Endotoxins

Differences between Exotoxins and Endotoxins

Differences between Exotoxins and Endotoxins Toxins are small molecules, peptides, or proteins produced by living cells that are capable of causing diseases or structural damage when they come in contact or are absorbed by tissues. Toxins and enzymes play an important role in the pathogenicity of pathogenic bacteria. Toxins may aid in invasiveness, damage cells, inhibit … Read moreDifferences between Exotoxins and Endotoxins

Protein Structure- Primary, Secondary, Tertiary and Quaternary

Protein Structure- Primary, Secondary, Tertiary and Quaternary

Four levels of hierarchy in protein conformation can be described. A. PRIMARY STRUCTURE PRIMARY STRUCTURE refers to the order of the amino acids in the peptide chain. 1. The free α-amino group, written to the left, is called the amino-terminal or N-terminal end. 2. The free α-carboxyl group, written to the right, is called the … Read moreProtein Structure- Primary, Secondary, Tertiary and Quaternary
