Proline Unit Converter
Proline (Pro) is a non-essential amino acid (specifically, an imino acid) that is a primary component of collagen, the most abundant protein in the body. It is vital for the structure of skin, tendons, and connective tissues.
Clinically, serum or plasma Proline levels are measured during **Amino Acid Analysis** to diagnose metabolic disorders such as **Hyperprolinemia** (Type I and II) or nutritional deficiencies. This converter facilitates switching between the standard SI molar units (µmol/L) and mass units (mg/dL, µg/mL).
SI Units / Standard
RecommendedMicromoles per liter (Standard for amino acid analysis).

Clinical Context
Reference Ranges (Plasma/Serum):
• Adults: 110 – 360 µmol/L (1.3 – 4.1 mg/dL).
• Infants: 85 – 290 µmol/L.
Clinical Significance: Markedly elevated levels (> 1000 µmol/L) may indicate **Hyperprolinemia Type I or II**, rare genetic disorders of proline metabolism.
Conversion Logic:
Molecular Weight of Proline: 115.13 g/mol.
1 mg/dL ≈ 86.86 µmol/L.
1 µmol/L ≈ 0.0115 mg/dL.

Frequently Asked Questions
It is considered “conditionally essential,” meaning the body can usually make enough, but supplementation may be needed during illness or stress.
It is measured as part of a Plasma Amino Acid profile to screen for inborn errors of metabolism.
