ACID HEMATIN Meaning and Definition

  1. Acid hematin is a chemical compound that forms as a result of the breakdown of hemoglobin, the iron-containing protein molecule found in red blood cells. When hemoglobin is exposed to certain acids, such as hydrochloric acid, it undergoes a chemical reaction that leads to the formation of acid hematin. Acid hematin is characterized by its dark brown to black color.

    The formation of acid hematin is commonly used as a biochemical test to identify the presence of blood in forensic analysis, as it provides a reliable indication of the presence of hemoglobin. This test is often used in criminal investigations to identify blood stains at crime scenes, as well as to distinguish between human and animal blood.

    In addition to its forensic applications, acid hematin also has medical significance. It serves as an indicator of the presence of blood in diagnostic tests, such as fecal occult blood tests, which are used to screen for diseases like colorectal cancer. Acid hematin can be detected in body fluids, such as urine and vomit, in cases of gastrointestinal bleeding or other medical conditions.

    Overall, acid hematin is a chemical compound formed from the breakdown of hemoglobin, used in various fields including forensics and medicine to identify the presence of blood and detect certain medical conditions.

Etymology of ACID HEMATIN

The word "acid hematin" is derived from two distinct sources.

1. Acid: The term "acid" derives from the Latin word "acidus", meaning sour. "Acid" is used to describe substances that have a pH value less than 7 and typically taste sour. It was first utilized in the late 16th century in English.

2. Hematin: Hematin is the reddish-brown pigment found in blood. The word "hematin" originates from the Greek word "haima", meaning blood, combined with the suffix "-in", denoting a substance. The term "hematin" was coined in the 19th century.

When combined, "acid hematin" refers to a compound formed when hemoglobin reacts with acid, resulting in the formation of acid hematin.
