How many different kinds of monomers are there in starch?

Also, what compound composes most of the cell membrane.

Since this is not my area of expertise, I searched Google under the key words "monomers starch" to get these possible sources:

You can do a similar search for your second question. In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps. Thanks for asking.

To determine how many different kinds of monomers are present in starch, you can break down the chemical structure of starch and identify the monomeric units.

Starch is a complex carbohydrate composed of glucose monomers. Specifically, it is made up of two types of glucose monomers: amylose and amylopectin.

1. Amylose: Amylose is a linear polymer of glucose units connected by α-1,4 glycosidic bonds. It consists of hundreds to thousands of glucose monomers linked in a linear chain.

2. Amylopectin: Amylopectin is a branched polymer of glucose units connected by α-1,4 and α-1,6 glycosidic bonds. It has a highly branched structure, with branch points occurring approximately every 20 to 30 glucose units.

To answer the question, there are technically two different kinds of monomers in starch: glucose monomers that are part of the linear amylose chains and glucose monomers that are part of the branched amylopectin chains.
