Androsterone is a DHEA metabolite via the 5-alpha-reductase pathway. The 5-alpha pathway is more androgenic.

Androsterone and Etiocholanolone are DHEA metabolites via Androstenedione and the 5α- and 5β-reductase pathways.

The ratio of Androsterone (5a) to Etiocholanolone (5b) in a Human Urinary Metabolic Profile (HUMAP) panel is a critical marker for assessing the balance of androgen metabolism in the body. Androsterone and Etiocholanolone are both metabolites of testosterone and other androgens, but they differ in their origins and physiological impacts. Androsterone, derived predominantly from the metabolism of testosterone, is associated with androgenic properties, playing a role in male characteristics and anabolic functions. In contrast, Etiocholanolone, though also a testosterone metabolite, does not possess androgenic activity and is a product of the 5β-reductase pathway.

Androsterone is the product of androgens metabolized by 5-alpha reductase. It acts as a neurosteroid and a weak potentiator of GABA-A receptor activity.

Angiotensin-converting enzyme (ACE) is an enzyme that helps regulate blood pressure.

An increased blood level of ACE is sometimes found in sarcoidosis, a systemic disorder of unknown cause that often affects the lungs but may also affect many other body organs, including the eyes, skin, nerves, liver, and heart.

The anion gap is a calculated value on a standard anion gap blood test that helps detect acid–base imbalances in the body. It is derived from electrolytes measured in a basic or comprehensive metabolic panel and is most commonly used to identify metabolic acidosis. A high anion gap may indicate acid buildup from conditions like kidney disease, diabetes, or lactic acidosis, while a low value is usually associated with low albumin levels. This marker is most useful when interpreted alongside other lab results such as bicarbonate, creatinine, and glucose.

Anserine (beta-alanyl-3-methyl-histidine) is a urinary biomarker from the consumption of poultry and fish. It is a dipeptide consisting of the amino acids 1-methylhistidine and beta-alanine. The enzyme carnosineN-methyl transferase catalyzes the transfer of a methyl group of S-adenosylmethionine (SAM) on carnosine to form anserine. Anserine acts as an antioxidant, free radical scavenger, and pH buffer. It can reduce blood sugar and affect renal sympathetic nerve activity and blood pressure. Anserine is measured in FMV urine only.
