Galactose Metabolism – Steps, Importance, Leloir Pathway

Galactose Metabolism - Steps, Importance, Leloir Pathway

What is Galactose? Galactose is a monosaccharide sugar that is an aldohexose. It is a C-4 epimer of glucose having the same structure as glucose, except that the atoms around carbon no. 4 are arranged differently. This sugar is around 65% of the sweetness of sucrose and is less sweet. It is paired with glucose … Read more

Glycogenesis – Enzymes, Steps, Regulation, Importance

Glycogenesis Steps

What is Glycogenesis? Definition of Glycogenesis Glycogenesis is the biological process of synthesizing glycogen from glucose molecules, primarily in the liver and muscles, for energy storage and glucose homeostasis. Key Enzymes in Glycogenesis Glycogenesis is the biochemical process that converts glucose into glycogen for storage in the liver and muscle tissues. This process relies on … Read more

Glycogenolysis – Enzymes, Steps, Regulation, Functions

Glycogenolysis - Enzymes, Steps, Regulation, Functions

What is Glycogenolysis? Glycogenolysis Definition Glycogenolysis is the enzymatic process of breaking down glycogen, a stored polysaccharide, into glucose-1-phosphate and glucose to provide energy or maintain blood sugar levels during fasting or increased energy demand. Glycogenolysis Location Glycogenolysis occurs in the cytoplasm of cells, primarily in the liver and skeletal muscles, with minimal activity in … Read more

Glycogen – Structure, Functions, Examples

Glycogen - Defintion, Structure, Functions, Examples

What is Glycogen? Definition of Glycogen Glycogen is a branched polysaccharide made of glucose units that serves as the primary form of glucose storage in animals, fungi, and bacteria. It is primarily stored in the liver and muscles and acts as a readily mobilized energy source when the body needs glucose. Characteristics of Glycogen Glycogen … Read more

Glycolysis – Definition, Steps, Enzymes, Regulation, Result

Glycolysis and Glycolytic Enzymes

What is glycolysis? Definition of glycolysis Glycolysis is a metabolic process in which glucose, a six-carbon sugar, is broken down into two three-carbon pyruvate molecules, producing a net gain of two ATP and two NADH molecules. This anaerobic pathway occurs in the cytosol and is a key step in cellular energy production. Major Features of … Read more
