Myoglobin (symbol Mb or MB) is an iron- and oxygen-binding protein found in the cardiac and skeletal muscle tissue of vertebrates in general and in almost all mammals. [5] [6] [7] [8] [9] Myoglobin is distantly related to hemoglobin.

2025年3月21日 · Myoglobin is a protein in your skeletal muscles and your heart. It transports oxygen from your bloodstream to your muscles. Your muscles need oxygen to work properly. Myoglobin is like a tiny delivery vehicle. It’s made of amino acids, iron and other molecules that work together to hold onto oxygen.

2023年6月29日 · Myoglobin is a protein that helps store oxygen in your muscle tissues. Learn about normal levels of myoglobin and what it means to have high amounts in your blood.

2023年7月17日 · Myoglobin is a protein located primarily in the striated muscles of vertebrates. MB is the gene encoding myoglobin in humans. It encodes a single polypeptide chain with one oxygen binding site.

Myoglobin (Mb) is an iron-containing heme protein that is present predominantly in the sarcoplasm of skeletal and cardiac muscles. Due to the presence of heme moiety, myoglobin serves as a carrier and store for oxygen in muscle cells of the body.

2023年4月13日 · Myoglobin is a small, globular protein consisting of a single polypeptide chain of 154 amino acids and an iron-containing heme prosthetic group, which is identical to that found in hemoglobin. Myoglobin can reversibly bind oxygen molecules and speed up the diffusion of oxygen into skeletal and cardiac muscle cells, where it is present.

Myoglobin is a protein found in the muscle cells of animals, where it functions as an oxygen-storage unit, providing oxygen to the working muscles.

This test measures the amount of a protein called myoglobin in your blood. It's done to help diagnose conditions caused by muscle damage. Myoglobin is found in your heart and skeletal muscles. There it captures oxygen that muscle cells use for energy. When you have a heart attack or severe muscle damage, myoglobin is released into your blood.

2022年4月28日 · Myoglobin is a protein found in the muscles and helps store oxygen and release it to the muscles during aerobic respiration. Myoglobin also functions as an oxygen carrier in the kidneys, and Myoglobin helps regulate renal blood flow and urine production in the kidneys.

2023年7月17日 · Myoglobin is a protein located primarily in the striated muscles of vertebrates. MB is the gene encoding myoglobin in humans. It encodes a single polypeptide chain with one oxygen binding site.
