| | Protein & Amino Acids- Ask the Dietitian |
 | | Protein once absorbed into the blood is filtered by the kidneys and if not used to build and repair muscle tissue, is converted to energy or stored as fat. | | | The RDA for protein is 63 gm for males and 50 gm for females. | | | Most of the amino acids (protein) in an egg are found in the white. |

| | Protein |
| | During the time it reigned supreme, there was very little human research being done on individual protein sources. | | | On the negative side, allergies are still possible with their use and depending on the type and quality of the protein concentrate, it may have high levels of fat or sugar and an absence of important individual amino acids such as glutamine. | | | Protein is made up of all L. However, there appears to be some therapeutic value to some of the D molecules such as DL-Phenylalanine for pain. |

| | You may think this is a trivial matter; however, incorrect information on our protein needs can have grave consequences on your health and your family’s health. | | | Consider the protein content of the foods we consume after weaning – these are even higher in protein – rice is 9%, potatoes are 8%, corn is 11% and oatmeal is 15% protein. | | | Following these studies, Chittenden in 1904 concluded that 35–50 g of protein a day was adequate for adults, and individuals could maintain their health and fitness on this amount. |

| | Thus, contrary to the widely held belief, the energetically preferred conformation of the main protein of bone and skin in physiological solution is a random coil rather than a triple helix. | | | Several proteins with antimicrobial activity, such as immunoglobulins, kappa-casein, lysozyme, lactoferrin, haptocorrin, alpha-lactalbumin, and lactoperoxidase, are relatively resistant against proteolysis in the gastrointestinal tract and may, in intact or partially digested form, contribute to the defense of breastfed infants against pathogenic bacteria and viruses. | | | For the group as a whole protein synthesis on 1.7 g protein/kg/d was 0.74, 0.75 and 0.87 g N/kg/d on 100, 90 and 80 kcal/kg/d respectively; whereas on 0.7 g protein/kg/d it was 0.37, 0.38 and 0.40 g N/kg/d. |

| | Contrary to popular belief, people who exercise vigorously or are trying to put on muscle mass don't need to consume extra protein. | | | This isn't true - it is stimulation of muscle tissue through exercise, not extra dietary protein that leads to muscle growth. | | | For elderly people, it is likely that protein intake at the upper end of the RDA range is desirable to maintain muscle mass and strength, which is a crucial component of walking ability. |

| | Protein phosphatases |
| | This somewhat paradoxical finding was intriguing since phosphatases were largely considered to be negative regulators of growth-promoting pathways characterized by extensive protein tyrosine phosphorylation. | | | The TCR is actually a complex of proteins that mediate antigen binding (i.e., such as small peptide sequences from viruses or bacteria) and transduction of a signal telling the T cell to divide, release soluble factors (lymphokines, interleukins, etc.), kill a virus-infected cell, etc. | | | The purpose behind creating a substrate trapping mutant phosphatase is to use such a reagent to trap or capture phosphoproteins that may serve as physiologic substrates for these enzymes in vivo. |
