After gastrectomy, malabsorption is a common condition

That may occur due to the reduced capacity of the digestive system to properly absorb nutrients.

Impaired digestion and nutrient absorption occur without the stomach, leading to malabsorption syndromes.

• Erythrocytes produce energy through glycolysis, which yields lactate as an end product.
• This lactate is normally transported out of the cell and into the bloodstream, but under certain conditions, it can accumulate in the cell.
• Microorganisms like bacteria and yeast, when growing under anaerobic conditions, also produce lactate as a byproduct of their metabolic processes, such as fermentation.

• It is composed of a backbone of alternating GlcNAc and MurNAc residues, cross-linked by short peptides.

Explanation
