Solution:
Because amino acids can be arranged in many different combinations, it's possible for our body to make thousands of different kinds of proteins from just the same 21amino acids. There are only 20 amino acids.
The 20 Amino acids which make proteins are:
• alanine - ala - A (gif, interactive)
• arginine - arg - R (gif, interactive)
• asparagine - asn - N (gif, interactive)
• aspartic acid - asp - D (gif, interactive)
• cysteine - cys - C (gif, interactive)
• glutamine - gln - Q (gif, interactive)
• glutamic acid - glu - E (gif, interactive)
• glycine - gly
Thus this is the required answer.
