Why are there so many kinds of protein?

Answer 1

Proteins are made up of 20 different amino acids, which can be arranged in countless sequences. This diversity in amino acid sequences allows for a wide variety of protein structures and functions. Additionally, proteins can undergo post-translational modifications, further increasing the number of possible protein variations. The vast array of proteins in living organisms is essential for carrying out the multitude of biological processes necessary for life.

Answer 2

We should note that enzymes are proteineous but not all enzymes are protein,actually it depends in the sequence of the amino acid polymerization,for instance in the change of valine of normal haemoglobin to glutamine of sickle haemoglobine and some protein constitute its monomers alone while others constitute another chemical component apart from their monomers.

Answer 3

there are 20 types of amino acids and a protein might be up to say 1000 amino acids long, that gives 201000 different possible protein combinations of that length. Far more than the number of subatomic particles in the entire universe. You also have to consider that proteins come in different lengths.

Answer 4

First there are 20 different amino acids that make up proteins.

With an average protein containing between 50 and 100 amino acids:

• a protein of 50 amino acids can have 20^50 different kinds, 112.59E63
• a protein of 100 amino acids can have 20^100 different kinds, or 12.677E129
• considering that proteins have different lengths, to find the total number of kinds of average proteins you need to compute the sum of the number of kinds of proteins with 50 amino acids, 51 amino acids, 52 amino acids, 53 amino acids, ..., 98 amino acids, 99 amino acids, and 100 amino acids
• considering that proteins come in lengths both shorter and longer than average, the number of kinds of those must also be included in this sum to get a final answer for the number of possible kinds of protein

A protein of 80 amino acids can have 120.89E102 different kinds, this number is already much larger than the number of subatomic particles in the known universe!

Answer 5

Proteins are made up of different sequences of amino acids, which can be combined in countless ways. This variety allows for the creation of different protein structures and functions, leading to the vast array of proteins found in living organisms. Each type of protein plays a specific role in the body, contributing to functions such as muscle contraction, immune response, and enzyme activity.

Answer 6

there are so many different kinds of proteins to carry out the various metabolisms there are so many different kinds of proteins to carry out the various metabolisms

Answer 7

For different functions in cells

Answer 8

Because that's what we were told
