What is the Difference Between Bile Salts and Bile Pigments

Thekey differencebetween bile salts and bile pigmentsis that bile salts are a primary component of bile made from the conjugation of bile acids with potassium ion or sodium ion, while bile pigments are a primary component of bile made by the decomposition of theporphyrinring.

Bile is a fluid made and released by the liver and stored in thegallbladder. It normally helps with digestion. Bile breaks down the fats into fatty acids. These fatty acids can be taken into the body by the digestive tract. The bile contains 98 % of water, 0.7 % of bile salts, 0.2 % of bilirubin (bile pigments), 0.51 % fats, and 200 meq/l of inorganic salts. Therefore, bile salts and bile pigments are two primary components of bile.

What are Bile Salts?

胆汁盐是由胆汁酸与钾离子和钠离子结合制成的胆汁的核心组成部分。胆汁酸是由肝细胞细胞in the liver. These bile acids are derived fromcholesterol. Bile salts are similar to bile acids. Bile salts are formed when bile acids bond to molecules of potassium or sodium. All bile salts consist of cholesterol-derived bile acid bound to potassium or sodium ions. Some primary bile salts are changed by intestinal bacteria by removing atoms. This creates what is known as secondary bile salts. Moreover, other bile salts conjugate with amino acids such as taurine and glycine to create conjugated bile salts.

胆汁和胆汁盐在体内的主要作用是通过分解脂肪，帮助吸收脂溶性维生素并消除废物产物来帮助消化。此外，如果由于胆囊清除等条件，人体没有产生足够的胆汁盐，则可能会经历并发症，例如腹泻，被困的气体，气味不良，胃痉挛，不稳定的肠运动，体重减轻和苍白的凳子。

What are Bile Pigments?

Bile pigments are a primary component of bile made by the decomposition of the porphyrin ring. They are also known as bilins or biplanes. Bile pigments are biological pigments in many organisms. They are metabolic by-products of certain porphyrins. Normally, bile pigments are found in many organisms, including mammals, vertebrates, invertebrates, red algae, green plants, and cyanobacteria.

In humans, they are coloured compounds and break down products of the blood pigment haemoglobin that are excreted in the bile. The two most important bile pigments are bilirubin, which is orange or yellow in colour, and biliverdin (oxidized form), which is green in colour. Furthermore, mixed with the intestinal contents, bile pigments give a brown colour to faeces (urobilinogen).

What are the Similarities Between Bile Salts and Bile Pigments?

• 胆汁和胆汁颜料是胆汁的两个主要成分。
• 这两个成分均由肝脏分泌，并传递给胆囊。
• They play important roles in the human body.

胆汁和胆汁颜料有什么区别？

Bile salts are a primary component of bile made from the conjugation of bile acids with potassium ion or sodium ion, while bile pigments are a primary component of bile made by the decomposition of the porphyrin ring. Thus, this is the key difference between bile salts and bile pigments. Furthermore, bile contains 0.7% of bile salts and 0.2% of bile pigments.

The below infographic presents the differences between bile salts and bile pigments in tabular form for side-by-side comparison.

Summary – Bile Salts vs Bile Pigments

Bile facilitates digestion and contains water, bile salts, bilirubin (bile pigments), fats, and inorganic salts. Bile salts are a primary component of bile made from the conjugation of bile acids with potassium ion or sodium ion, while bile pigments are a primary component of bile made by the decomposition of the porphyrin ring. So, this is the key difference between bile salts and bile pigments.
