Difference Between Chlorophyll A and B

Thekey difference在叶绿素A和B之间是叶绿素A是植物中的主要光合色素，algaewhile the chlorophyll B is an accessory pigment that collects energy and passes to chlorophyll A.

Chlorophyll is a family of natural pigments that are present in plants and algae and is responsible for their green colour. Chlorophyll absorbs energy from sunlight and makes use of this energy to synthesize carbohydrates from water and carbon dioxide. It is the process calledphotosynthesisthat sustains life processes in all plants as their energy requirements are met through this process. Furthermore, photosynthesis is the prime process that sustains all living organisms since plants are the primary producers of all food chains. Animals and humans consume products of plants. In the chlorophyll pigment family, there are several types of chlorophyll pigments. Among them, chlorophyll A and chlorophyll B are two types of chlorophylls. They have a similar structure with a slight difference in the porphyrin ring. Chlorophyll A has CH₃卟啉环中的基团在卟啉环中具有CHO（醛组）。

什么是叶绿素a?

Chlorophyll A is the primary photosynthetic pigment present in plants and algae. It is the most widely distributing type of chlorophylls. It is a greenish colour pigment, which is able to capture energy from sunlight and produce foods in光自人营养。有两种类型的光系统涉及光反应。

在两个光系统中，反应中心由叶绿素A分子组成。它们吸收红色，蓝色和紫罗兰色波长，并反射绿色。在考虑结构时，它的卟啉环类似于叶绿素B。然而，叶绿素A的卟啉环具有CH₃侧组。

什么是叶绿素B?

叶绿素B是植物和绿藻中存在的辅助光合色素。它通过收集能量并传递给它来帮助叶绿素a。与叶绿素A类似，它是一种绿色色素。此外，它具有与叶绿素A的结构相似的结构。

但是，其卟啉环包含一个CHO组，该基团在叶绿素A中不存在。光系统i。Compared to chlorophyll A, chlorophyll B is less abundant. Furthermore, chlorophyll B is more soluble in polar solvents than the chlorophyll A. It primarily absorbs blue light.

What are the Similarities Between Chlorophyll A and B?

• Chlorophyll A and B are two types of chlorophylls which are green colour pigments.
• Both involve in photosynthesis.
• Also, both are able to absorb energy from sunlight.
• Furthermore, both are present in photosynthetic organisms, especially in green plants and algae.
• 此外，它们的两个结构都由卟啉环组成。
• 而且，它们都是感光体，因为它们可以利用阳光为植物制作食物。

叶绿素A和B之间有什么区别？

Chlorophyll A is the most abundant universal type of greenish colour chlorophyll pigment present in plants, algae and cyanobacteria. Thus, it is the primary photosynthetic pigment which absorbs light from red, blue and violet wavelengths and reflects green. Likewise, chlorophyll A is present within the reaction centres of both photosystems. On the other hand, chlorophyll B is an accessory pigment which collects energy and hand over to chlorophyll A. Therefore, this is the key difference between chlorophyll A and B.

Also, there is a difference between chlorophyll A and B in their structure. Chlorophyll A contains CH₃side groups attached to porphyrin ring while chlorophyll B has a CHO group attached to the porphyrin ring. More description about the difference between chlorophyll A and B is given in the below infographic.

概括– Chlorophyll A vs B

In brief, Chlorophyll A and B are two types of green colour pigments of chlorophyll family. Chlorophyll A is the primary photosynthetic pigment while the chlorophyll B is an accessory pigment. On the other hand, Chlorophyll B collects energy and passes to chlorophyll A for exciting. Thus, this is the key difference between chlorophyll A and B. Furthermore, they have a small difference in their structures such as chlorophyll B has an aldehyde group attached to porphyrin ring unlike in chlorophyll A.
