19. Glycine is an amino acid that can be abbreviated HGly. If 27.50 mL of 0.120 M NaOH neutralizes 0.248 g of HGly, what is the molar mass of the amino acid? HGly(aq) + NaOH(aq) ï® NaGly(aq) + H 2 O(l) MV = moles (0.120 M) (0.02750L) = 0.033 mole NaOH = 0.0033 mole HGly 0.248 g / 0.0033 mole HGly = 75.12 g/mol HGly 20.
Spirulina is a type of blue-green algae that is rich in protein, vitamins, minerals, carotenoids, and antioxidants that can help protect cells from damage.
Because it contains all of the essential amino acids, spirulina is considered a complete protein source. It also contains several vitamins, with about 1 milligram each of vitamin C and thiamine, and small amounts of several other B-vitamins in each 100-gram serving.
