Question

Question 2 and question 3 Question 2 (1 point) Amino acids are all water soluble. are identical in one part of their structure: the R-group. come in 20 different kinds. all have an amino group on one end, a carboxyl group on the other end, and an alpha-carbon in the middle Save Question 3 (1 point) We can tell how an amino acid will be classified (as polar or non-polar) by looking at it to see whether it has a charge (-or +) in its amino group; this will make it non-polar. it has a charge (-or + ) in its R-group: this will make it polar. it has an electronegative atom (like oxygen) in its carboxyl group: this will classify it as polar, ithas a chain or ring in its R-group; this will make it insoluble in water (and thus non-polar).
