| 单词 | proline |
| 例句 | Gelatin is made almost entirely of protein — 98 to 99% to be exact, per Healthline — and contains several amino acids, including proline and glycine, which both help rebuild tissue that lines the digestive tract. No, those TikTok-famous collagen gummies aren't a healthy meal replacement 2023-02-26T05:00:00Z I have been taking niacin for years along with vitamin C and the amino acids lysine and proline. Lowering a little-known cardiac risk factor 2023-06-14T04:00:00Z They devised tRNAs that actively ruin viral proteins by delivering the wrong amino acids—including proline and alanine—in response to outsiders’ serine codons. Rewritten genetic code allows bacteria to fend off viral attacks 2022-10-19T04:00:00Z He tested whether proline could catalyze an aldol reaction, in which carbon atoms from two different molecules bond together. Nobel Prize in Chemistry Awarded to Scientists for Tool That Builds Better Catalysts 2021-10-06T04:00:00Z If scientists want a kink in their Slinky, they can add a proline, which does not form a bond and allows the rest of the helix to bend away from it. Artificial Proteins Never Seen in the Natural World Are Becoming New COVID Vaccines and Medicines 2021-06-22T04:00:00Z All they had to do was change two of more than 1,000 building blocks in the protein into a compound called proline. Researchers Are Hatching a Low-Cost Coronavirus Vaccine 2021-04-05T04:00:00Z Mutations in crucial proline residues within this domain abrogated the effects of RANK–RANKL reverse signalling. Receptor becomes a ligand to control bone remodelling 2018-09-04T04:00:00Z This mutation, in which the usual amino-acid residue proline is replaced by leucine, is identical to a change that causes diabetes and health problems in humans5,6. The healthy diabetic cavefish conundrum 2018-03-20T04:00:00Z The reaction worked, proving that proline was an excellent catalyst and that an amino acid can drive what is known as asymmetric catalysis. Nobel Prize in Chemistry Awarded to Scientists for Tool That Builds Better Catalysts 2021-10-06T04:00:00Z Altered intracellular processing and release of neuropeptide Y due to leucine 7 to proline 7 polymorphism in the signal peptide of preproneuropeptide Y in humans. Genetic variation in glia–neuron signalling modulates ageing rate 2017-11-07T05:00:00Z The resulting spike — called 2P, for the two new proline molecules it contained — was far more likely to assume the desired tulip shape. Researchers Are Hatching a Low-Cost Coronavirus Vaccine 2021-04-05T04:00:00Z The gene that enables CCC to be translated into proline could then be deleted entirely. Biologists are close to reinventing the genetic code of life 2016-08-18T04:00:00Z The Harvard researchers also experimented with a drug, halofuginone, that mimics deprivation of proline, an amino acid essential during times of illness or stress. Dietary restriction before surgery may help prevent some complications 2012-01-26T02:44:00Z Nothing is known, however, of the process by which the more complicated closed-ring amino-acid compounds, such as proline, histidine, or tryptophane, are synthetized. The Chemistry of Plant Life As a result, the genetic code has multiple codons for the same amino acid: the codons CCC and CCG both encode the amino acid proline, for example. Biologists are close to reinventing the genetic code of life 2016-08-18T04:00:00Z |
