Out of 20 amino acids our body can easily synthesize a few on its own and are called non-essential amino acids. A The products of protein digestion may be absorbed as free amino acids or as di- or tripeptides b Gastric digestion of all proteins is equally efficient because of the grinding action of the antrum.

D Saturated fats tend to be liquid at room temperature due to hydrogen bonding. B The empirical formula for lipids is typically C 1 H 2 O 1.
C Amino acids are often linked together to form branched polymers. Positively charged basic amino acids are. A Lipids are synthesized by ribosomes.
Correct option is A a R group on the side chain on the amino acid provides variation. Which of the following statements regarding lipids is most accurate. Glycine is a diprotic amino acid which means that it has two dissociable Protons one on the α amino group and the other on the carboxyl group.
All twenty amino acids were quantified using commercially available isotope labeled internal standards within a linear range of four orders of magnitude that accurately accounts for losses in signal intensities interference from the biological matrix and degradation that otherwise are problematic 25 40. The statement is false. The isoelectric point pI is the pH at which a particular molecule carries no net electrical charge.
