glutathione metabolism pentose pathway Glucose begins with its transport into cells via GLUT transporters, where it is phosphorylated to glucose-6-phosphate (Glucose-6-P). This molecule can enter various pathways, including the phosphate or hexosamine biosynthesis The return of metabolism: biochemistry

Mitochondrial biogenesis and clearance: a balancing act

This mitochondrial GSH reservoir is regulated by specific transport proteins, such as SLC25A39, which are vital for preserving mitochondrial redox balance and shielding the organelle from oxidative injury [41]

Because plant foods do not contain vitamin B12, vegans and vegetarians are at risk of developing deficiency and need to incorporate other sources of vitamin B12 into their diets, such as supplements, fortified breakfast cereals and plant milks, nutritional yeast, and fermented soybeans (tempeh).6 In addition to inadequate dietary intakes, vitamin B12 deficiency is caused by diminished or absent production in the gut of hydrochloric acid and intrinsic factor, both of which promote the absorption, transport, and uptake of vitamin B12 by cells
