Lesson Outline Introduction to Pentose Phosphate Pathway Location: Cytosol of mammary glands, liver, adrenal cortex, adipose tissue, and red blood cells Connection to nucleotide synthesis and NADPH production Oxidative Phase Irreversible reactions Glucose-6-phosphate (G6P) conversion to 6-phosphogluconolactone and eventually to ribulose-5-phosphate G6P dehydrogenase: rate-limiting step Production of first NADPH 6-phosphogluconate dehydrogenase: conversion to ribulose-5-phosphate Production of second NADPH and carbon dioxide Non-oxidative Phase Reversible reactions Phosphopentose isomerase: conversion of ribulose-5-phosphate to ribose-5-phosphate Transketolase: conversion of ribose-5-phosphate to glyceraldehyde-3-phosphate and fructose-6-phosphate Both intermediates enter glycolysis G6PD Deficiency X-linked recessive metabolic disease Hemolytic anemia during periods of oxidative stress Decrease in NADPH and low availability of active glutathione Triggers: infections, inflammatory conditions, fava beans, and certain drugs Peripheral blood smear findings: Heinz bodies and bite cells Hemoglobinuria Prevalence in people of African, Middle Eastern, or Mediterranean descent Protection against malaria Don't stop here

However, reduced dietary intake due to appetite suppression and gastrointestinal side effects may indirectly increase deficiency risk, particularly if consumption of B12-rich animal products decreases significantly

A great way to start is by using a lower concentration, around 1% , and just paying attention to how your skin responds as you introduce this powerhouse peptide into your routine
