Biochemistry : Amino Acids Quiz
Amino Acids are organic molecules that have both an amino group (-NH2) and a carboxyl group (-COOH). There are 20 different amino acids commonly found in living things, and humans can produce 10 of them. The other ten must come from food. Amino acids combine to form amides that release water via condensation.
Peptides are amino acid combinations in which the amino groups on one are united with a carboxyl group of another. The amide bond that joins two amino acids is called a peptide bond. A chain of 10 or more peptides is called a polypeptide, and a chain of 50 or more peptides is called a protein.
Below is the list of the 20 amino acids and their abbreviations.
Asparagine—Asn Aspartic acid—Asp
Cysteine—Cys Glutamic acid—Glu
