Try this. I embedded the test data to simplify testing:

data = """48 ALA H = 8.33 N = 120.77 CA = 55.18 HA = 4.12 C = 181.50
104 ALA H = 7.70 N = 121.21 CA = 54.32 HA = 4.21 C =
85 ALA H = 8.60 N =  CA =  HA = 4.65 C =""".split('\n')
for line in data:
    line2 = line.split('=')
    if not line2[5]: # C value missing
      if len(line2[2]) <= 5 and len(line2[3]) <= 5: # N and CA values 
missing
        print "all missing", line
      else:
        print "C missing", line
