Proteins are ______________ built from amino acids, which each have an amino group and a _____________ group attached to the central _______________. There are twenty possible _______________ that differ in structure and are generally referred to as “R.” In solutions of neutral pH, amino acids are _______________, carrying both a positive and negative charge. When a protein is made, amino acids are linked together through _______________, which are formed by condensation reactions between the carboxyl end of the last amino acid and the ___________________ end of the next amino acid to be added to the growing chain.
a: amino | b: ionized | c: polypeptides |
d: alpha-carbon | e: length | f: protein |
g: carbon | h: noncovalent | i: R group |
j: carboxyl | k: peptide bonds | l: side chains |
m: hydroxide
. Proteins are polypertides built from amino acids, which each have an amino group and a carboxyl group attached to the central alpha-carbon. There are twenty possible R group that differ in structure and are generally referred to as “R.” In solutions of neutral pH, amino acids are ionized, carrying both a positive and negative charge. When a protein is made, amino acids are linked together through peptide bonds, which are formed by condensation reactions between the carboxyl end of the last amino acid and the amino end of the next amino acid to be added to the growing chain.
